2 Object/Parameter descriptionThis section gives the description of customer available objects and parameters.

Introduction

Parameters belong to a containing object. Object descriptions can be found in the first volume.

In the volumes 2 to 9, the parameters are grouped by Network Element: CNode, INode, NodeB,OAM, POC7K, POC15K (each volume is dedicated to 1 Network Element) and by containing object(those objects being alphabetically sorted for each Network Element).

For further information on the parameters network engineering, please contact your AccountManager who will support you into getting the UTRAN Parameters User Guide (UPUG) issued byAlcatel-Lucent Wireless Network Engineering group.

Object description

Each object is presented as follows: Unique Name (Name).

RNC objects have a unique name different from their name.

NodeB and OAM objects have a unique name equal to their name.

In each volume (from volume 2 to 9), the objects are sorted by alphabetical order according to theirUnique Name.

For each object, the following general information are presented:

• presence: the value of this field can be "optional" or "required"

• onlineCreation: the value of this field can be "AllowedWithParent" or "Allowed" or "NotAllowed".

• onlineDeletion: the value of this field can be "AllowedWithParent" or "Allowed" or "NotAllowed".

• verbs: the value of this field can be "add" or/and "delete", and it is used for Passportprovisioning.

• parents: this field gives the list of the containing objects

• children: this field gives the list of the contained objects

• identifiers: this field gives the list of the identifiers, and for each one, the correspondingIDcategory, IDqualifier, IDscope, Mininstances, Maxinstances as follows:

Name IDcategory IDqualifier IDscope Mininstances Maxinstances

Parameter description

For each parameter, the following fields are presented:

• parameter name

4


• domain: the three kinds of domains are:

— RNC: parameters are part of the RNC MIB definition and are hosted by WMS OAM andNetwork Element RNC

— BTS: parameters are part of the BTS MIB definition and are hosted by WMS OAM andNetwork Element BTS

— IN: parameters are part of the Inode MIB definition and are hosted by WMS OAM andNetwork Element Inode

— AN: parameters are part of the Anode MIB definition and are hosted by WMS OAM andNetwork Element Anode

— OAM: parameters are part of the WMS OAM MIB definition and are hosted by WMS OAMonly. Its are not declared in any Network Element MIB, so its are not mediated by buildfunction and not checked by audit function.

• description: the parameter definition

• class: the five kinds of class are:

— 0: The parameter cannot be modified and a new object instance must be created with therequested parameter value thanks to build process or on line command.

— 1: The object instance does not need to be locked to modify the parameter and themodification will be taken into account after the NE has restarted.

— 2: The object instance (or one of the parent object instance) must be locked to modify theparameter and the modification will be taken into account after the object instance (or theparent object instance) has been unlocked.

— 3: So called "on-line parameter definition". The object instance does not need to be locked tomodify the parameter and the modification will immediately be taken into account with noimpact on the service availability.

— READ ONLY: The "read only" parameters can only be displayed.

• presence: indicates if the configuration of the parameter is optional.

• visibility

Customer parameter accessible for the customer (read/write or read only)

Manufacturer Alcatel-Lucent defines these parameters and they are not accessible forcustomer

Customer Re-stricted

parameters that can be modified by the customer, but it is strongly recom-mended to set them according to Alcatel-Lucent specification as their modi-fications can have performance impacts on WMS

• data type: decimal, integer, float, boolean, etc.

• unit: the measurement unit of the value range, when applicable.

• range: the parameter value range. For example:

— Float: min = -35, max = 15, step = 0.1

— Enum (AdministrativeState): locked (0), unlocked (1), shuttingdown (2)

— String: length = 40 (Hex)

— Integer: min = 0, max = nRouteSet-1

• initial value: the value of a new parameter is [#false#] or [#null#] or [x]. This value is used:

— either when a customer wants to ensure the same performances before a UTRAN releaseupgrade

— or when a customer wants to deactivate a function

• def value comments

• recommended value: this value is recommended by Alcatel-Lucent for new networks roll outbefore the optimization. The recommended values take benefit of the performance ofAlcatel-Lucent UTRAN feature. For installed networks, the value to set depends on the chosenoptions or rules defined by the customer.

• rec val comments

Index description

At the end of each volume (from volume 2 to volume 9), two indexes are available summarizing allthe parameters presented in the concerned volume:

6


• an index for the customer parameters

• an index for the manufacturer parameters

These two indexes list the parameters by category (standard, inventory, states and status, dynamicdata, I&C) and by object sorted by alphabetical order, as follows:

• standard parameters

— Object A

– Parameter AA

– Parameter AB

– Parameter AC

— Object B

– Parameter BA

– Parameter BB

• inventory parameters

If a component has acid attribute, the component's CID is the provi-sioned value of that attribute; otherwise the com-ponent inherits the CID of its parent. The top- levelcomponent has a CID of 0. Every operator sessionalso has a CID, which is the CID provisioned for theoperator's user ID. An operator will see only thestream data for components having a matchingCID. Also, the operator will be allowed to issuecommands for only those components which have amatching CID. An operator CID of 0 is used toidentify the Network Manager (referred to as "Net-Man" in DPN). This CID matches the CID of anycomponent. Values 1 to 8191 inclusive (equivalentto "basic CIDs" in DPN) may be assigned to specificcustomers.

A class buffer pool limit isdesigned to prevent one emission priority from con-suming all the available buffer space. The eight buf-ferLimitPerEP values represent maximum buffersize per emission priority, in number of cells. Toguarantee proper buffer isolation among emissionpriorities, the sum of bufferLimitPerEP values for allemission priorities must not exceed the total bufferspace available, which is 261118 cells. The defaultvalues are approximately 15%, 0%, 15%, 50%,15%, 0%, 0%, and 5% of total available bufferspace for emission priorities 0 through 7 respect-ively. Note: For APC based cards, the minimum

Description This attribute specifies the high priority Early PacketDiscard (EPD) offset for connection queues. OnATM IP FPs a given connection queue is associ-ated with one of eight emission priorities (EP).These include six unshaped EPs, one exclusiveVBR shaper EP and one ABR/VBR shaper EP. Thisattribute specifies the EPD offset for the exclusiveVBR shaper EP and the first four (higher priority)unshaped EPs. This offset is used to derive a con-nection EPD threshold for a given Congestion Con-trol (CC) level by subtracting the offset from the AllPacket Discard (APD) threshold at the same CClevel. The APD thresholds are themselves derivedfrom the transmit queue limit. The EPD thresholdonly applies to a connection if the Packet-Wise Dis-card feature is requested. The Packet-Wise Discardfeature can be enabled only if the transmit queuelimit is at least 5.71 times the EPD offset. This en-sures that the derived EPD threshold will never beless than 17.5% of the transmit queue limit. If thiscondition is not satisfied, the Packet-Wise Discardfeature for the connection is automatically disabled.Due to the above constraint, if the operator wishesto decrease the transmit queue limit and still havethe Packet-Wise Discard feature enabled on theconnection then this offset must be set to a lowervalue that meets the above requirement. Due tohardware granularity the actual value of the EPDoffset may not match exactly the value provisioned.The actual value is displayed under the ATM Con-nection Administrator service category subcompon-ents on ATM IP FPs.

portCongestionPolicy

Parameter name portCongestionPolicy

Domain

Description This attribute specifies the congestion behavior ofall ports on this FP. It applies only to transmit trafficand does not apply to the CBR service category.When the value is aggregate, the enqueue decisionof cells or frames to a queue is based upon the con-gestion state of the entire port to which the queue

25


belongs. A port is defined to be as congested as themost congested queue amongst all its queues.Thus, for example, if an nrt-VBR queue is conges-ted, the rt-VBR queue also experiences discardseven though the rt-VBR queue may itself not becongested. Setting this attribute to aggregate as-sures that the low priority queues are also servicedin the event of congestion. If this attribute is set toaggregate then rt-VBR must not be configured to docommon queuing and its emission priority should beset to a number numerically smaller than or equal to3. Another impact of setting this attribute to aggreg-ate is that the per connection queue limits for nrt-VBR and UBR connections will be increased to thelink pool size and their discard thresholds will bemodified to be aligned with the free list discardthresholds. When the value of this attribute is set toindividualQueue, the enqueue decision of cells orframes to a queue is based solely upon the conges-tion state of that queue, not the port. This settingassures that the absolute priority of the traffic istaken into account, regardless of whether the lowerpriority queues are being served. On3pOC3SmAtm2 and 3pOC3MmAtm2 cards, if morethan one override component exists, they musthave the same setting for this attribute. Otherwise,setting the attribute under one override componentapplies to the entire card.

Description Lp/n Eng Arc Aqm/n The Aqm component de-scribes the usage of ATM-specific resources on aLogical Processor running ATM services for a spe-cific ATM Queue Manager. This component is al-ways dynamically created under any LP Eng whichsupports an ATM IP FP. The number of instancesdepends upon the type of card. For the 4-port OC3cards, in unprotected mode one AQM instance isused per Sonet or SDH port, where the AQM in-stance is the same as the Sonet or SDH port in-

34


stance. For example, Sonet/0 uses AQM/0. In pro-tected mode, ports 0 and 1 work together and ports2 and 3 work together. If ports 0 and 1 are a protec-tion pair, then AQM/0 is used. AQM/1 is dormant. Ifports 2 and 3 are a protection pair, then AQM/2 isused. AQM/3 is dormant. For the 32pE1MsaMtp,32pE1MsaMt, 32pDS1MsaMtp, 32pDS1MsaMt,32pE1MsaStp, 32pE1MsaSt, 32pDS1MsaStp and32pDS1MsaSt cards, AQM/0 exists for the E1 orDS1 electrical ports and AQM/1 exists for the Sonetor SDH optical ports. Optical ports 0 and 1 can onlyboth exist, as a protected pair. For the 32pE1Msaand 32pDS1Msa cards, only AQM/0 exists for theE1 or DS1 electrical ports. For the1pOC12SmLrAtm card, only AQM/0 exists. Twophysical ports exist, but if both ports are provisionedthe second may be used for protection only. For12pDS3Atm and 12pE3Atm cards, an AQM in-stance exists for each set of three ports. As clarific-ation, DS3/0, DS3/1, and DS3/2 use AQM/0. DS3/3,DS3/4, and DS3/5 use AQM/1. DS3/6, DS3/7, andDS3/8 use AQM/2. DS3/9, DS3/10, and DS3/11 useAQM/3.

If theLogical Processor is associated with a card of oneof the following card types: 16pOC3SmIrAtm,4pOC12SmIrAtm, 4pOC12SmLrAtm,1pOC48ChSmIrAtm, the maximum value for opera-tional attribute protectedConnectionPoolAvailable is56000. To achieve the maximum protectedConnec-tionPoolAvailable, the Lp Eng Fcrc Pqc OvipRoutesPoolCapacity must be provisioned to 0.This requires there to be no IP features in the relev-ant sw lpt featurelist. If the total number of connec-tions defined by adding the values of the protected-ConnectionPoolCapacity and the connectionPool-Capacity attributes can not be satisfied, then theprotectedConnectionPoolCapacity requirements aresatisfied before the requirements of the connection-PoolCapacity.

Description This attribute specifies the peak-to-peak cell delayvariation (CDV) which is contributed to the entireATM Interface for CBR traffic (excluding connec-tions managed by a Vpt CA). The CDV is a meas-ure of the delay jitter introduced mostly by trafficbuffering and cell scheduling.

This attribute isused by the Connection Admission Control (CAC)algorithm to compute the equivalent cell rate (ECR)required by a given CBR connection. The larger thevalue of CDVT, the larger is its ECR. If Usage Para-meter Control (UPC) is enabled for a connection,

cellLossRatio

Parameter name cellLossRatio

Domain

Description This attribute specifies the tolerable cell loss ratio(CLR) for CBR traffic (excluding connections man-aged by a Vpt CA). The value specified is the neg-ative base 10 logarithm of the CLR. For example, ifthe target CLR = 1E-10 then the value of thecellLossRatio attribute is 10. The value of this attrib-ute must be the same as the value of the RtVbrcellLossRatio attribute since CBR and rt-VBR traffichave the same discard priority. This attribute isused by the Connection Admission Control (CAC)algorithm to compute the equivalent cell rate (ECR)required for CBR connections. There is a trade-offbetween the service category CLR and the achiev-able link utilization. To guarantee an excellent ser-vice category, the CLR should be as small as pos-sible (for example, 1E- 10). However, a smallerCLR results in a larger equivalent cell rate for a giv-en connection and hence a lower link utilization. Avalue of anyClrValue means that no bandwidth isreserved for CBR connections, and CAC is effect-ively turned off. All CBR connections are admitted.

Description This attribute specifies the emission priority (EP)which is used to transmit traffic of the CBR servicecategory. A lower numerical value for this attributespecifies a higher emission priority. 0 is the highestEP and 7 is the lowest. Cells at a higher emissionpriority receive higher preference for link bandwidth.EP 0 and EP 1 are in the absolute priority rangeand are unaffected by any minimum bandwidthguarantees. EP 2 through EP 7 are in the guaran-teed bandwidth range and may achieve a prioritywhich is different from the strict hierarchical priority,if a minimum bandwidth guarantee is provisioned. Aminimum bandwidth guarantee is specified in theAtmIf/n Ep/m component. This attribute does notapply to basic VPTs, or standard Vpt VCCs.

The queue limit of aper-VC queue is obtained by scaling down thetxQueueLimit attribute based on the shaping rate ofthat queue (shaping rate for the connection and forstandard Vpt VCCs, the shaping rate of the Vptcomponent). This produces a constant delay forvarious queue lengths. The value of thetxQueueLimit attribute provides an upper boundwhile the value of the minPerVcQueueLimit attributeprovides the lower bound. The value of this attributemust not be greater than the value of thetxQueueLimit attribute. If this service category isused by Trunks, the value of the minPerVc-QueueLimit attribute must be at least 88. For VPTs,this attribute does not apply. Regardless of theVpt's service category, standard VPTs always usethe AtmIf CA NrtVbr minPerVcQueueLimit value astheir default.

shapeRecoupPolicy

Parameter name shapeRecoupPolicy

Domain

Description This attribute specifies the shaping recoup policy forthe CBR service category. This is the policy whichis used to recoup shaping opportunities which arelost when more than one connection schedules acell for the same transmit opportunity. In this case,one connection is scheduled and the cell from theother connection is delayed by one cell time. Thisattribute affects how the transmit time is calculatedfor the next cell on the delayed connection. This at-tribute is ignored if this service category is notshaped. This attribute does not apply to basicVPTs, or standard Vpt VCCs. This attribute is notapplicable and is ignored for 4pOC12SmIrAtm,4pOC12SmLrAtm, and 16pOC3SmIrAtm cards.When the connection which was delayed schedulesthe next cell to transmit, it may calculate the time asa difference from either the previous actual celltransmit time, or the time when the previous cellshould have been transmitted. A value of maxim-umEfficiency results in each connection trying to re-coup or regain any delays in scheduling. The trans-mit time for the next cell is calculated from the timewhen the previous cell should originally have beensent. Cell delay variation (CDV) occurs in this casesince the cells are sent with less than the shapingdelay between them. However, in general theshaper recovers (recoups) lost opportunities andimproves efficiency. A value of minimumCdv resultsin connections not trying to recoup or regain anydelays in scheduling. The transmit time for the nextcell is calculated from the time when the previouscell was actually transmitted. This minimizes CDV,but results in missed cell opportunities.

Description This attribute specifies the default holding prioritywhich applies to SVC CBR point-to-multipoint con-nections. It takes a value from 0 (highest priority) to4 (lowest priority). In a situation where the linkbandwidth fluctuates, such as over an IMA link,holding priority is used to determine which connec-tions are held and which are released. Holding pri-ority 4 connections are the first to be released.Holding priority 0 connections are the last to be re-leased. This attribute does not apply to Vpt VCCs.When bandwidth fluctuates, the entire Vpt compon-ent, along with all Vpt VCCs is released as a unit,according to the Vpt's holdingPriority.

Description This attribute specifies the default traffic shapingoption for connections of the CBR service category.An override to this default may be specified for aprovisioned connection under the Vcd Tm or VpdTm component. This attribute does not apply to ba-sic VPTs, or standard Vpt VCCs. A value of dis-abled means traffic shaping cannot be enabled forany CBR connections. For 3pOC3MmAtm,3pOC3SmAtm, 3pE3Atm, 3pDS3Atm, 3pE1Atm,3pDS1Atm, 8pE1Atm, 8pDS1Atm, 2pJ6MAtm,1pOC12SmLrAtm, and 1pOC48ChSmIrAtm cards,the value of this attribute must be disabled sincetraffic shaping is not supported for CBR connec-tions on these cards. If the Vcc Tm, Vpc Tm, or VptTm, txTrafficDescType attribute indicates type 1 or

2, this attribute is ignored and traffic shaping is notapplicable for that connection. A value of in-verseUpc means traffic shaping for a connection isenabled according to the value of the Vcc Tm, VpcTm, or Vpt Tm txTrafficDescType attribute. A valueof inverseUpc when the txTrafficDescType is 3, 4,or 5, means linear traffic shaping is enabled. Lineartraffic shaping uses a single static traffic shapingrate. A value of inverseUpc when the txTrafficDesc-Type is 6, 7, or 8, means inverse-UPC (also re-ferred to as VBR or dual leaky bucket) traffic shap-ing is enabled. Inverse-UPC traffic shaping canburst above the sustained cell rate to the peak cellrate for the duration defined by the maximum burstsize. Inverse-UPC traffic shaping exactly conformsto the requirements of a dual leaky bucket UPC en-forcer. For 4pOC12SmIrAtm, 4pOC12SmLrAtm,and 16pOC3SmIrAtm cards, the value inverseUpcis not available. A value of enabled when the txTraf-ficDescType is 3, 4, 5, 6, 7, or 8, means lineartraffic shaping is enabled.

txQueueLimit

Parameter name txQueueLimit

Domain

Description This attribute specifies the default maximum queuelength for the emission queues used to buffer thetraffic of the CBR service category. It is used as thebasis for setting both the queue length and the dis-card thresholds on both common and per-VCqueues. For the common queue, the discardthresholds are set at approximately 35, 75, and 90percent of the value of this attribute for traffic at dis-card priority 3 (DP=3), DP=2 and DP=1 respect-ively. For 4pOC12SmIrAtm, 4pOC12SmLrAtm, and16pOC3SmIrAtm cards, common queuing is notavailable for the CBR service category. For a per-VC queue, the actual queue length may be reduceddepending on the shaping rate of the connection(for standard Vpt VCCs, this is the shaping rate ofthe Vpt component). The discard thresholds are setat approximately 35, 75 and 90 percent of thescaled queue limit for traffic at discard priority 3(DP=3), DP=2 and DP=1 respectively. However, areduction will never result in a value that is lessthan the value of the minPerVcQueueLimit attribute.The per-VC queue limit may be overridden for aprovisioned connection by specifying a value in theVcd Tm or Vpd Tm txQueueLimit attribute. For3pOC3MmAtm, 3pOC3SmAtm, 3pE3Atm,3pDS3Atm, 3pE1Atm, 3pDS1Atm, 8pE1Atm,8pDS1Atm, 2pJ6MAtm, 1pOC12SmLrAtm, and1pOC48ChSmIrAtm cards, per-VC queues are notavailable for the CBR service category. For1pOC48ChSmIrAtm cards, this attribute is used toset the maximum size of the link-class queue forbuffering the egress traffic of the CBR service cat-egory. This is similar to common queuing, exceptthat each CBR connection maintains a per-VC util-ization limit of the common queue specified for aprovisioned connection by the Vcd Tm or Vpd TmtxQueueLimit attribute. A value of autoConfiguremeans an appropriate value is selected based onthe card type. For 3pOC3MmAtm, 3pOC3SmAtm,3pE3Atm, 3pDS3Atm, 3pE1Atm, 3pDS1Atm,8pE1Atm, 8pDS1Atm, 2pJ6MAtm, 2pOC3MmAtm2,

weightPolicy

Parameter name weightPolicy

Domain

Description This attribute specifies the policy which is appliedwhen calculating the fairness weight for unshapedconnections of the CBR service category. The fair-ness weight for a connection determines the relat-ive amount of bandwidth which that connection ob-tains, compared to other connections in the sameservice category. Connections with equal weight getequal transmit opportunities. Connections with high-er weights get more transmit opportunities com-pared with connections that have lower weights. Anoverride to this default may be specified for a provi-sioned connection under the Vcd Tm or Vpd Tmcomponent. The fairness weight for a connection isdirectly proportional to the value of one of the trafficdescriptor parameters for that connection. This at-tribute specifies which traffic descriptor parameter isused for connections of the CBR service category.A value of scr means the fairness weight is propor-tional to the transmit sustained cell rate (SCR) of a

100


connection. Connections with a higher SCR have ahigher fairness weight. For connections with txTraf-ficDescType 3, which have no SCR, the sustainedcell rate is assumed to be equal to the peak cellrate. A value of pcr means the fairness weight isproportional to the transmit peak cell rate (PCR) ofa connection. Connections with a higher PCR havea higher fairness weight. Connections with txTraffic-DescType 1 or 2 get a minimum weight, which is 1.A value of ecr means the fairness weight is propor-tional to the equivalent cell rate (ECR) of a connec-tion as calculated by connection admission control(CAC). Connections with a higher ECR have a high-er fairness weight. Connections with an ECR of 0get a minimum weight, which is 1. The weight of aconnection is visible in the Vcc Tm, Vpc Tm, or VptTm weight attribute. This attribute does not apply tobasic VPTs and standard Vpt VCCs. This attributeis ignored if the value of the unshapedTrans-mitQueueing attribute is common.

atmServiceCategory

Parameter name atmServiceCategory

Domain

Description This attribute specifies the ATM service category forboth directions of the connection. The constant-BitRate service category is intended for real timeapplications, that is those requiring tightly con-strained delay and delay variation, as would be ap-propriate for voice and video applications. The con-sistent availability of a fixed quantity of bandwidth isconsidered appropriate for CBR service. Cellswhich are delayed beyond the value specified byCellTransfer Delay are assumed to be of signific-

102


antly reduce value to the application. The rtVari-ableBitRate service category is intended for realtime applications, that is those requiring tightly con-strained delay and delay variation, as would be ap-propriate for voice and video applications. Sourcesare expected to transmit at a rate which varies withtime. Equivalently, the source can be described as"bursty". Cells which are delayed beyond the valuespecified by CTD are assumed to be of significantlyreduced value to the application. Real time VBRservice may support statistical multiplexing of realtime sources. The nrtVariableBitRate service cat-egory is intended for non-real time applicationswhich have bursty traffic characteristics and whichcan be characterized in terms of a PCR, SCR, andMBS. For those cells which are transferred withinthe traffic contract, the application expects a lowcell loss ratio. For all connections, it expects abound on the mean cell transfer delay. Non-realtime VBR service may support statistical multiplex-ing of connections. The unspecifiedBitRate serviceis intended for non-real time applications; that is,those not requiring tightly constrained delay anddelay variation. UBR sources are expected to bebursty. UBR service supports a high degree of stat-istical multiplexing among sources. UBR servicedoes not specify traffic related service guarantees.No numerical commitments are made with respectto the cell loss ratio experienced by a UBR connec-tion, or as to the cell transfer delay experienced bycells on the connection.

Description This attribute is a vector of five traffic parameterswhose meanings are defined by the trafficDescTypeattribute. The values of peak cell rate (PCR), sus-tained cell rate (SCR) and requested shaping rateare expressed in cell/s. Maximum burst size (MBS)is expressed in cells. CDVT is expressed in micro-seconds. The values of PCR, SCR, MBS and CDVTare used for connection admission control (CAC).The value of CDVT is only used for connectionswhere the atmServiceCategory is constantBitRate.For all other values of atmServiceCategory, CDVTis ignored. The values of PCR, SCR and requestedshaping rate are used to determine the actual shap-ing rate where traffic shaping is enabled. When traf-ficDescType is 3, parameter 1 represents the PCRfor CLP equal to 0 and 1 traffic; parameter 4 repres-ents the CDVT; and parameter 5 represents the re-quested shaping rate. A non-zero value in paramet-er 5 overrides any value in parameter 1. This resultis used as the PCR. Parameter 1 must be non-zero.Parameters 2 and 3 must be zero. When traffic-DescType is 6, parameter 1 represents the PCR forCLP equal to 0 and 1 traffic; parameter 2 repres-ents the SCR for CLP equal to 0 and 1 traffic; para-meter 3 represents the MBS for CLP equal to 0 and1 traffic; parameter 4 represents the CDVT; and

104


parameter 5 represents the requested shaping rate.A non-zero value in parameter 5 overrides anyvalue in parameter 1. This result is used as thePCR. Parameters 1, 2, and 3 must be non-zero.Parameter 1 must be greater than or equal to para-meter 2. Parameter 5 must either be zero (unused)or greater than or equal to parameter 2. When traf-ficDescType is 7, parameter 1 represents the PCRfor CLP equal to 0 and 1 traffic; parameter 2 repres-ents the SCR for CLP equal to 0 with cell discard;parameter 3 represents the MBS for CLP equal to 0traffic; parameter 4 represents the CDVT; and para-meter 5 represents the requested shaping rate. Anon-zero value in parameter 5 overrides any valuein parameter 1. This result is used as the PCR.Parameters 1, 2, and 3 must be non-zero. Paramet-er 1 must be greater than or equal to parameter 2.Parameter 5 must either be zero (unused) or great-er than or equal to parameter 2. When trafficDesc-Type is 8, parameter 1 represents the PCR for CLPequal to 0 and 1 traffic; parameter 2 represents theSCR for CLP equal to 0 traffic with cell tagging;parameter 3 represents the MBS for CLP equal to 0traffic; parameter 4 represents the CDVT; and para-meter 5 represents the requested shaping rate. Anon-zero value in parameter 5 overrides any valuein parameter 1. This result is used as the PCR.Parameters 1, 2, and 3 must be non-zero. Paramet-er 1 must be greater than or equal to parameter 2.Parameter 5 must either be zero (unused) or great-er than or equal to parameter 2. Whenever it is validfor PCR to be specified, parameter 5 may also beused to specify a requested shaping rate. A non-zero value in parameter 5 overrides the value inparameter 1 and is used as the peak cell rate in cal-culations of CAC and shaping rate. For trafficDesc-Type 3 the traffic is shaped at the next rate lessthan the PCR. For trafficDescType 6, 7, and 8, thetraffic is shaped at the highest available rate whichis between PCR and SCR. However, if there is noavailable shaping rate between PCR and SCR,traffic is shaped at the next rate above the PCR.

Description This VCD component has an attribute that is calledatmServiceCategory. This attribute specifies theservice category that is used by the sig, rcc or ilmichannel. The weight attribute is related to two otherattributes which are weightPolicy and txQueueLimit,as mentioned in the following description. These at-tributes can be found under the atmif/n ca<atmServiceCategory>/ m. This attribute specifiesan override for the weight of this unshaped connec-tion. This attribute is ignored for shaped connec-tions, for ABR connections, for connections on aCQC-based ATM FPs and basic VPTs. When thevalue is set to sameAsCa, the weight is determinedby the weightPolicy attribute under the CA servicecategory component for all but standard VPT VCCs.For standard VPT VCCs, the weight is determinedby the VCC's service category, when the value isset to sameAsCa. When this attribute is set to avalue from 1 to 4095, that value is used for theweightPolicy of this connection relative to other con-nections. For all but standard VPT VCCs, weight-Policy determines the proportion of transit cell op-portunities which are allocated to this connection,compared to other connections in the same servicecategory. For standard VPT VCCs, weightPolicy de-termines the proportion of transmit cell opportunitieswhich are allocated to this connection, compared toother connections associated with the VPT. Whenthe value is set to upToQueueLimit, the weight-Policy is limited only by the txQueueLimit.

Description AtmIf/n EmissionPriority/n This component controlsthe characteristics of an emission priority for an At-mIf component. This component is optional for anAtmIf component. For 3pOC3MmAtm,3pOC3SmAtm, 3pE3Atm, 3pDS3Atm, 3pE1Atm,3pDS1Atm, 8pE1Atm, 8pDS1Atm, 2pJ6MAtm, and1pOC48ChSmIrAtm cards, this component is notpermitted. There are eight emission priorities (EP).EP 0 is the highest priority and EP 7 is the lowestpriority. Normally, link bandwidth is allocated in

116


strict precedence of emission priority. All traffic atEP 0 is transmitted on the link first. Then, whenthere is an unused cell opportunity, a cell from EP 1is transmitted. When EP 0 and 1 have nothing tosend, then EP 2 gets the transmit cell opportunities.Each emission priority 2 through 7 has a corres-ponding Ep component with instance number 2through 7. Emission priorities 0 and 1 do not havecorresponding Ep components since there is noconfiguration which is relevant for those EPs. Trafficis associated with an EP in the following way. EachVcc or Vpc has an associated atmServiceCategory.Under the AtmIf component there is a service cat-egory component which provides default character-istics for that service category. For example, AtmIf/n CA Cbr/0 defines the default characteristics forconnections of the CBR service category. Each ser-vice category has an emissionPriority (ep) attribute,for example AtmIf/n CA Cbr/0 ep. The value provi-sioned in that ep attribute maps to the correspond-ing Ep component. If the value of the AtmIf/n CACbr/0 ep attribute is 2, the CBR service category isassociated with AtmIf/n Ep/2. EP 0 and EP 1 are inthe absolute priority range. Traffic in the absolutepriority range always gets first choice for a transmitcell opportunity. EP 2 through EP 7 are in the guar-anteed bandwidth range. Traffic at EP 3 through EP7, in the guaranteed bandwidth range, may achievea priority which is different from the strict hierarchic-al priority, if a minimum bandwidth guarantee is pro-visioned for the Ep. For 4pOC12SmIrAtm,4pOC12SmLrAtm, and 16pOC3SmIrAtm cards,EPs 5 and 6 are not supported. For16pOC3PosAtm and 4pMRPosAtm cards, EP 0 andEP 1 are in the absolute priority range while EP 2through EP 7 are allocated link bandwidth using aconventional Weighted Fair Queue (WFQ) discip-line. EP 2 through EP 7 have their service prefer-ence over one another determined by their minim-um bandwidth guarantee. Link bandwidth is first al-located to EP 0 and EP 1 in absolute priority fash-ion. Any remaining bandwidth is distributed to EP 2through EP 7 in proportion to the minimum band-width guarantee provisioned for the Ep. The defaultvalues of the minimumBandwidthGuarantee attrib-ute for the Ep components emulate the strict pre-cedence of emission priority.

minimumBandwidthGuarantee

Parameter name minimumBandwidthGuarantee

Domain

Description This attribute specifies the minimum bandwidthguarantee associated with this EmissionPriority. Aminimum bandwidth guarantee is designed to pre-vent starvation of traffic at this EP by traffic at high-er EPs. Minimum bandwidth guarantees only oper-ate for EPs within the guaranteed bandwidth range2 through 7. For 4pOC12SmIrAtm,4pOC12SmLrAtm, and 16pOC3SmIrAtm cards,EPs 5 and 6 are not supported. For2pOC3MmAtm2, 2pOC3SmAtm2, 2pSTM1eAtm,2pSTM1eCh, 2pSTM1Ch, 4pOC3MmAtm,4pOC3SmIrAtm, 4pDS3ChAtm, 3pDS3Atm2,3pE3Atm2, 12pDS3Atm, 12pE3Atm, MSA32,1pOC12SmLrAtm, 4pOC12SmIrAtm,4pOC12SmLrAtm, and 16pOC3SmIrAtm cards, thefollowing description applies: The minimum band-width guarantee specified is a percentage of thebandwidth which remains after all traffic at EP 0 andEP 1 is served. For example, if EP 0 and EP 1traffic consumes 20% of the link bandwidth, theminimum bandwidth guarantee applies to the re-maining 80% of the link bandwidth. A minimumbandwidth guarantee of 2% would actually result inthis EP getting 2% of 80% for a total 1.6% of thelink bandwidth. If this EP uses less than this linkbandwidth, the extra opportunities are allocated tothe other EPs in priority. Due to scheduling and cellarrival times, traffic at this EP may not necessarilyachieve full utilization of its minimum bandwidthguarantee. The value priority specifies that this Epgets bandwidth based solely on the hierarchy ofemission priorities. In this case, there is no minim-um bandwidth guarantee. For 16pOC3PosAtm and4pMRPosAtm cards, the following description ap-plies: The minimum bandwidth guarantee specifiedis the proportion of the bandwidth which remainsafter all traffic at EP 0 and EP 1 is served. In otherwords, the bandwidth allocated to an EP is:(bandwidth unused by EP 0 and 1) * minimumBand-

118


widthGuarantee (the sum of the values of the min-imumBandwidthGuarantee attributes for all activeEPs) For example, if EP 0 and EP 1 traffic con-sumes 20% of the link bandwidth, the minimumbandwidth guarantee applies to the remaining 80%of the link bandwidth. Assume Ep/2, Ep/3, and Ep/4have a minimumBandwidthGuarantee attributevalue of 70, 20, and 10 respectively. If all EPs areactively sending traffic, then the bandwidth is alloc-ated as follows: - EP 2 = 80% * 70/(70+20+10) =56% of the link bandwidth - EP 3 = 80% *20/(70+20+10) = 16% of the link bandwidth - EP 4 =80% * 10/(70+20+10) = 8% of the link bandwidth Ifsome time later EP 3 has no traffic to send, then itsshare of the bandwidth is allocated to EP 2 and EP4 in proportion to their minimumBandwidthGuaran-tee attribute values as follows: - EP 2 = 80% *70/(70+10) = 70% of the link bandwidth - EP 4 =80% * 10/(70+10) = 10% of the link bandwidth Ifsome time later only one out the EP 2, EP 3, andEP 4 has traffic to send, then it would be allocatedthe entire 80% of the link bandwidth. Additionally, ifboth EP 0, and EP 1 have no traffic to send, the re-maining active EP would be allocated 100% of thelink bandwidth irrespective of the value of its minim-umBandwidthGuarantee attribute. The value priorityemulates the strict precedence of emission priorityby assigning default values to the minimumBand-widthGuarantee attribute. Depending on how manyEPs are in use in the guaranteed bandwidth range2 through 7, these default values change: - For oneEP, the value is 100. - For two EPs, the values are99, and 1. - For three EPs, the values are 90, 9,and 1. - For four EPs, the values are 77, 18, 4, and1. For all cards, when specifying a value for theminimumBandwidthGuarantee attribute, considerthe effect on cell delay variation (CDV) of trafficwhich would normally be of higher priority. For ex-ample, if RtVbr service category traffic is assignedto Ep/2 and Ubr traffic is assigned on Ep/7 whereEp/7 has a minimumBandwidthGuarantee of 25,there can be a large impact on the CDV of theRtVbr traffic. Traffic of the Cbr or RtVbr service cat-egory which is sensitive to CDV, and is of knownvolume, can be assigned on EP 0 or EP 1 whichare independent of the effects of minimum band-width guarantee. For 2pOC3MmAtm2,2pOC3SmAtm2, 2pSTM1eAtm, 2pSTM1eCh,2pSTM1Ch, 4pOC3MmAtm, 4pOC3SmIrAtm,4pDS3ChAtm, 3pDS3Atm2, 3pE3Atm2,12pDS3Atm, 12pE3Atm, MSA32, and

For 4pOC12SmIrAtm, 4pOC12SmLrAtm,16pOC3SmIrAtm, 16pOC3PosAtm, and4pMRPosAtm cards, the allowed values of this at-tribute are priority, or a numeric value between 1and 100. For all cards, the sum of the values of theminimumBandwidthGuarantee attribute for all Epsunder an AtmIf component must not exceed 100%.

Parameter name bandwidthElastic

Domain

Description This attribute is only of importance for connectionswhich are carried on a link with a variable band-width. For example, the bandwidth may be reducedin the event that one or more physical links in theIMA group fail, such that the originally requestedbandwidth cannot be maintained. This attributeshows whether the application running on this con-nection can continue to operate if the bandwidth is

reduced. If the bandwidth is reduced, the amount bywhich it is reduced will be displayed in the bandwid-thReduction attribute. A value of yes, indicates thatthis connection is elastic, and the bandwidth maybe reduced but the connection will not be released.Currently, this attribute should only be set to yes forsituations where this Nrp is functioning as a loop-back on one side of an IMA link. There are no othersituations where this setting is valid. A value of noindicates that the bandwidth for this connection willnot be reduced in the event of link bandwidth reduc-tion.

cellLossRatio


Domain

Description This attribute specifies the tolerable cell loss ratio(CLR) for nrt- VBR traffic (excluding connectionsmanaged by a Vpt CA). The value specified is thenegative base 10 logarithm of the CLR. For ex-ample, if the target CLR = 1E-10 then the value ofthe cellLossRatio attribute is 10. The value if this at-tribute must be less than or equal to the value of theRtVbr cellLossRatio attribute since rt-VBR traffichas a higher discard priority. This attribute is usedby the Connection Admission Control (CAC) al-gorithm to compute the equivalent cell rate (ECR)required for nrt-VBR connections. There is a trade-

148


off between the service category CLR and theachievable link utilization. To guarantee an excel-lent service category, the CLR should be as smallas possible (for example, 1E- 10). However, a smal-ler CLR results in a larger equivalent cell rate for agiven connection and hence a lower link utilization.A value of anyClrValue means that no bandwidth isreserved for nrt-VBR connections and CAC is ef-fectively turned off. All nrt- VBR connections are ad-mitted.

emissionPriority


Domain

Description This attribute specifies the emission priority (EP)which is used to transmit traffic of the nrt-VBR ser-vice category. A lower numerical value for this at-tribute specifies a higher emission priority. 0 is thehighest EP and 7 is the lowest. Cells at a higheremission priority receive higher preference for linkbandwidth. EP 0 and EP 1 are in the absolute prior-ity range and are unaffected by any minimum band-width guarantees. EP 2 through EP 7 are in theguaranteed bandwidth range and may achieve apriority which is different from the strict hierarchicalpriority, if a minimum bandwidth guarantee is provi-sioned. A minimum bandwidth guarantee is spe-cified in the AtmIf/n Ep/m component. This attributedoes not apply to basic VPTs, or standard VptVCCs.

This attribute is ignored for1pOC12SmLrAtm cards, because they do not sup-port per-VC queues for the nrt-VBR service cat-egory. The queue limit of a per-VC queue is ob-tained by scaling down the txQueueLimit attributebased on the shaping rate of that queue (shapingrate for the connection and for standard Vpt VCCs,the shaping rate of the Vpt). This produces a con-stant delay for various queue lengths. The value ofthe txQueueLimit attribute provides an upper boundwhile the value of the minPerVcQueueLimit attributeprovides the lower bound. The value of this attributemust not be greater than the value of thetxQueueLimit attribute. If this service category isused by Trunks, the value of the minPerVc-QueueLimit attribute must be at least 88. This attrib-ute is used as the default minPerVcQueueLimit forall standard VPTs, regardless of the Vpt's servicecategory. This attribute does not apply to basicVPTs.

Description This attribute specifies the shaping recoup policy forthe nrt-VBR service category. This is the policywhich is used to recoup shaping opportunitieswhich are lost when more than one connectionschedules a cell for the same transmit opportunity.In this case, one connection is scheduled and thecell from the other connection is delayed by one celltime. This attribute affects how the transmit time iscalculated for the next cell on the delayed connec-tion. This attribute is ignored if this service categoryis not shaped. This attribute does not apply to basicVPTs, or standard Vpt VCCs. This attribute is notapplicable and is ignored for 4pOC12SmIrAtm,4pOC12SmLrAtm, and 16pOC3SmIrAtm cards.When the connection which was delayed schedulesthe next cell to transmit, it may calculate the time asa difference from either the previous actual celltransmit time, or the time when the previous cellshould have been transmitted. A value of maxim-umEfficiency results in each connection trying to re-coup or regain any delays in scheduling. The trans-mit time for the next cell is calculated from the timewhen the previous cell should originally have beensent. Cell delay variation (CDV) occurs in this casesince the cells are sent with less than the shapingdelay between them. However, in general theshaper recovers (recoups) lost opportunities andimproves efficiency. A value of minimumCdv resultsin connections not trying to recoup or regain anydelays in scheduling. The transmit time for the nextcell is calculated from the time when the previouscell was actually transmitted. This minimizes CDV,but results in missed cell opportunities.

An override to this default may be specifiedfor a provisioned connection under the Vcd Tm orVpd Tm component. This attribute does not apply tobasic VPTs, or standard Vpt VCCs. A value of dis-abled means traffic shaping cannot be enabled forany nrt-VBR connections. For 1pOC12SmLrAtmand 1pOC48ChSmIrAtm cards, the value of this at-tribute must be disabled since traffic shaping is notsupported for nrt-VBR connections on these cards.For 3pOC3MmAtm, 3pOC3SmAtm, 3pE3Atm,3pDS3Atm, 3pE1Atm, 3pDS1Atm, 8pE1Atm,8pDS1Atm, and 2pJ6MAtm cards, the value of thisattribute may be enabled only if the interface sup-ports shaping, as defined by the perVcQueueInter-faces attribute of the Lp Eng Arc Cqc Ov compon-ent. If that component does not exist, the value ofthis attribute must be disabled. If the Vcc Tm, VpcTm, or Vpt Tm txTrafficDescType attribute indicatestype 1 or 2, this attribute is ignored and traffic shap-ing is not applicable for that connection. A value ofinverseUpc means traffic shaping for a connection

157


is enabled according to the value of the Vcc Tm,Vpc Tm, or Vpt Tm txTrafficDescType attribute. Avalue of inverseUpc when the txTrafficDescType is3, 4, or 5, means linear traffic shaping is enabled.Linear traffic shaping uses a single static trafficshaping rate. A value of inverseUpc when the tx-TrafficDescType is 6, 7, or 8, means inverse-UPC(also referred to as VBR or dual leaky bucket) trafficshaping is enabled. Inverse-UPC traffic shaping canburst above the sustained cell rate to the peak cellrate for the duration defined by the maximum burstsize. Inverse-UPC traffic shaping exactly conformsto the requirements of a dual leaky bucket UPC en-forcer. For 4pOC12SmIrAtm, 4pOC12SmLrAtm,and 16pOC3SmIrAtm cards, the value inverseUpcis not available.

A value of enabled when thetxTrafficDescType is 3, 4, 5, 6, 7, or 8, means trafficshaping for a connection is enabled using linearshaping.

Description This attribute specifies the default maximum queuelength for the emission queues used to buffer thetraffic of the nrt-VBR service category. It is used asthe basis for setting both the queue length and thediscard thresholds on both common and per-VCqueues. For the common queue, the discardthresholds are set at approximately 35, 75, and 90percent of the value of this attribute for traffic at dis-card priority 3 (DP=3), DP=2, and DP=1 respect-ively. For 4pOC12SmIrAtm, 4pOC12SmLrAtm, and16pOC3SmIrAtm cards, common queuing is notavailable for the nrt-VBR service category. For aper-VC queue, the actual queue length may be re-duced depending on the shaping rate of the con-nection (for standard Vpt VCCs, this is the shapingrate of the Vpt). The discard thresholds are set atapproximately 35, 75, and 90 percent of the scaledqueue limit for traffic at discard priority 3 (DP=3),DP=2, and DP=1 respectively. However, a reduc-tion will never result in a value that is less than thevalue of the minPerVcQueueLimit attribute. Theper- VC queue limit may be overridden for a per-manent connection by specifying a value in the VcdTm or Vpd Tm txQueueLimit attribute. For1pOC12SmLrAtm and 1pOC48ChSmIrAtm cards,per-VC queues are not available for the nrt-VBRservice category. For 1pOC48ChSmIrAtm cards,this attribute is used to set the maximum size of thelink-class queue for buffering the egress traffic ofthe nrt-VBR service category. This is similar to com-mon queuing, except that each nrt-VBR connectionmaintains a per-VC utilization limit of the commonqueue specified for a provisioned connection by theVcd Tm or Vpd Tm txQueueLimit attribute. A valueof autoConfigure means an appropriate value is se-lected based on the card type. For 3pE1Atm,3pDS1Atm, 8pE1Atm, 8pDS1Atm, 2pJ6MAtm,2pSTM1eCh, 2pSTM1Ch and 4pDS3ChAtm cards,

Description This attribute specifies the default queuing optionfor unshaped connections of the nrt-VBR servicecategory. This attribute controls whether commonor per-VC queuing is used. A value of perVc meansthat each connection has its own buffering andqueue limits. A value of common means that cellsare queued in First In First Out order on a commonqueue for this service category. The commonqueue has one set of congestion control levels forall cells enqueued on it. This attribute does not ap-ply to basic VPTs, or standard Vpt VCCs. For3pOC3MmAtm, 3pOC3SmAtm, 3pE3Atm,3pDS3Atm, 3pE1Atm, 3pDS1Atm, 8pE1Atm,8pDS1Atm, and 2pJ6MAtm cards, if the perVc-QueueInterfaces attribute of the Lp Eng Arc Cqc Ovcomponent permits shaping for this interface, thenthis attribute may take any of the three values. Inthis case, the value autoConfigure is interpreted tomean per-VC queuing. If the perVcQueueInterfacesattribute of the Lp Eng Arc Cqc Ov component doesnot permit shaping for this interface, then this attrib-ute may take the values common, or autoConfigure.In this case, the value autoConfigure is interpretedto mean common queuing. An override to this de-fault may be specified for a provisioned connectionunder the Vcd Tm, or Vpd Tm component. There isone common queue which is shared by the nrt-VBR, ABR, and UBR service categories. For1pOC12SmLrAtm and 1pOC48ChSmIrAtm cards,the value perVc is not supported since these cardsdo not support per-VC queuing. The value autoCon-figure is interpreted to mean common queuing. For4pOC12SmIrAtm, 4pOC12SmLrAtm, and16pOC3SmIrAtm cards, the value common is notsupported since these cards do not support com-mon queuing. The value autoConfigure is inter-preted to mean per-VC queuing. For2pOC3MmAtm2, 2pOC3SmAtm2, 2pSTM1eAtm,2pSTM1eCh, 2pSTM1Ch, 4pOC3MmAtm,4pOC3SmIrAtm, 4pDS3ChAtm, 3pDS3Atm2,3pE3Atm2, 12pDS3Atm, 12pE3Atm, MSA32,16pOC3PosAtm, and 4pMRPosAtm cards, if trafficshaping for this service category is disabled, this at-tribute may take any of the three values. In thiscase, the value autoConfigure is interpreted tomean per-VC queuing. If traffic shaping for this ser-vice category is not disabled, the only permitted val-ues are perVc and autoConfigure. In this case, the

162


value autoConfigure is interpreted to mean per-VCqueuing. For 16pOC3PosAtm and 4pMRPosAtmcards, no more than 32,000 connections on the FPcan use per-VC queuing. The remaining connec-tions must use common queuing. The Lp Eng ArcperVcQueueUsage attribute indicates the numberper-VC queues that are currently in use.

This attribute is ignored if the rx-TrafficDescriptorType indicates 1 or 2. An overrideto this default may be specified for a provisionedconnection under the Vcd Tm or Vpd Tm compon-ent. A value of enforced means UPC is enforced foreach connection. When UPC is enforced, non-conforming cells are either tagged or discarded de-pending on the rxTrafficDescriptorType. A value ofmonitored means UPC conformance checking isperformed, except, instead of the non-conformingcells being tagged or discarded, they are merelycounted in the UPC violations counts and passedon unchanged. A value of disabled means UPC isdisabled on the receive path for all rt-VBR connec-tions. This attribute does not apply to basic VPTs,or standard Vpt VCCs.

weightPolicy


Domain

Description This attribute specifies the policy which is appliedwhen calculating the fairness weight for unshapedconnections of the nrt-VBR service category. Thefairness weight for a connection determines the rel-ative amount of bandwidth which that connectionobtains, compared to other connections in the sameservice category. Connections with equal weight getequal transmit opportunities. Connections with high-er weights get more transmit opportunities com-pared with connections that have lower weights. Anoverride to this default may be specified for a provi-sioned connection under the Vcd Tm or Vpd Tmcomponent. The fairness weight for a connection isdirectly proportional to the value of one of the trafficdescriptor parameters for that connection. This at-tribute specifies which traffic descriptor parameter isused for connections of the nrt-VBR service cat-egory. A value of scr means the fairness weight isproportional to the transmit sustained cell rate(SCR) of a connection. Connections with a higherSCR have a higher fairness weight. For connec-tions with txTrafficDescType 3, which have no SCR,the sustained cell rate is assumed to be equal tothe peak cell rate. A value of pcr means the fairnessweight is proportional to the transmit peak cell rate(PCR) of a connection. Connections with a higherPCR have a higher fairness weight. Connectionswith txTrafficDescType 1 or 2 get a minimumweight, which is 1. A value of ecr means the fair-ness weight is proportional to the equivalent cellrate (ECR) of a connection as calculated by con-nection admission control (CAC). Connections witha higher ECR have a higher fairness weight. Con-nections with an ECR of 0 get a minimum weight,which is 1. The weight of a connection is visible inthe Vcc Tm, Vpc Tm, or Vpt Tm weight attribute.This attribute does not apply to basic VPTs andstandard Vpt VCCs. This attribute is ignored if the

A route cache entryconsists of one or more paths and support calls ofcertain traffic requirements. A path becomes invalidif it can no longer support the traffic requirements ofthe associated route. This may happen if any linkalong the path fails, or its capacity is reduced. If thisattribute is set to yes, the whole route cache entrywill be purged after a path becomes invalid. If thisattribute is set to no, only the path will be removed.For most networks, it is desirable to purge thewhole route cache entry when one path becomesinvalid since this allows for better load balancing.However, for some network scenarios, this behavioris not desirable, because it may lead to many unne-cessary route cache purges at high network utiliza-tion.

maxPaths

Parameter name maxPaths

Domain

Description This attribute specifies the maximum number ofpaths to be used for load balancing and route cach-ing. Setting this attribute to 1 turns the load balan-cing off for all load balancing technique except formaxAvCr. This load balancing technique requiresmaxPaths to be set to 1. When the Artg Pnni Cachecomponent is provisioned, this attribute also spe-cifies the maximum number of paths to be stored ina route Cache entry for each destination node. Set-ting this attribute to a value greater than 3 is not re-commended except for certain specific topologies.In these cases, it allows a better load distributionwhen route cache is used. However, for other topo-logies, it will significantly slow down on-demandroute computation. Also when this attribute is set toa value greater than 3, the Artg Pnni lb<srvCat>method attribute can only be set to random. Whenthis attribute is set to a value greater than 3,maxNumEntries in the Artg Pnni Cache subcom-ponent is limited to ensure that maximum memoryconsumption by the route cache on the CP does notincrease when maxPaths is greater than 3. maxNu-mEntries may not exceed the value of 30000/ max-Paths.

minVariance

Parameter name minVariance

Domain

Description This attribute specifies the minimum variance valueto be used for each optimization metric supportedby the service category of this LoadBalancing in-stance. This attribute is a vector indexed by the op-timization metric. Note that the values of this vectorare explicit values as opposed to the factors re-quired to set the slopeVariance attribute. A largervariance allows more usable paths to be consideredfor load balancing. A low variance of zero meansthat only the slopeVariance attribute is used in de-termining the acceptable variance. The maximumrange boundaries for each of the optimization met-rics are: - cdv: 2147483647 (for cbr and rtVbr only).- maxCtd: 2147483647 (for cbr and rtVbr only). -aw: 4294967295. The acceptable variance is calcu-

196


lated based on the following formula: acceptabl-eVariance = minVariance + optM * slopeVariance/100 where optM represents the optimization metricvalue of the best path.

cdvt

Parameter name cdvt

Domain

Description This attribute specifies the default cell delay vari-ation tolerance (CDVT) for all connections of the rt-VBR service category (including connections man-aged by a Vpt CA). An override to this default maybe specified for a provisioned connection under theVcd Tm or Vpd Tm component. If Usage ParameterControl (UPC) is enabled for a connection, CDVT isused by the UPC function to decide whether a cellis conforming or non-conforming based on the con-nection's traffic descriptor type. The larger the CD-VT value, the more tolerant is the UPC of band-

cellLossRatio


Domain

Description This attribute specifies the tolerable cell loss ratio(CLR) for rt- VBR traffic (excluding connectionsmanaged by a Vpt CA). The value specified is thenegative base 10 logarithm of the CLR. For ex-ample, if the target CLR = 1E-10 then the value ofthe cellLossRatio attribute is 10. The value of thisattribute must be the same as the value of the CbrcellLossRatio attribute since CBR and rt-VBR traffichave the same discard priority. The value if this at-tribute must also be greater than or equal to thevalue of the NrtVbr cellLossRatio attribute since rt-VBR traffic has a higher discard priority. This attrib-ute is used by the Connection Admission Control(CAC) algorithm to compute the equivalent cell rate(ECR) required for rt- VBR connections. There is atrade-off between the service category CLR and theachievable link utilization. To guarantee an excel-lent service category, the CLR should be as smallas possible (for example, 1E- 10). However, a smal-ler CLR results in a larger equivalent cell rate for agiven connection and hence a lower link utilization.A value of anyClrValue means that no bandwidth isreserved for rt- VBR connections, and CAC is ef-fectively turned off. All rt-VBR connections are ad-mitted.

emissionPriority


Domain

Description This attribute specifies the emission priority (EP)which is used to transmit traffic of the rt-VBR ser-vice category. A lower numerical value for this at-tribute specifies a higher emission priority. 0 is thehighest EP and 7 is the lowest. Cells at a higheremission priority receive higher preference for linkbandwidth. EP 0 and EP 1 are in the absolute prior-ity range and are unaffected by any minimum band-width guarantees. EP 2 through EP 7 are in theguaranteed bandwidth range and may achieve apriority which is different from the strict hierarchicalpriority, if a minimum bandwidth guarantee is provi-sioned. A minimum bandwidth guarantee is spe-cified in the AtmIf/n Ep/m component. This attributedoes not apply to basic VPTs, or standard VptVCCs.

Description This attribute specifies the minimum queue limit forthe per-VC queues of connections of the rt-VBRservice category. This attribute is ignored for1pOC12SmLrAtm cards, because they do not sup-port per-VC queues for the rt-VBR service category.The queue limit of a per-VC queue is obtained byscaling down the txQueueLimit attribute based onthe shaping rate of that queue (shaping rate for theconnection and for standard Vpt VCCs, the shapingrate of the Vpt component). This produces a con-stant delay for various queue lengths. The value ofthe txQueueLimit attribute provides an upper boundwhile the value of the minPerVcQueueLimit attributeprovides the lower bound. The value of this attributemust not be greater than the value of thetxQueueLimit attribute. If this service category isused by Trunks, the value of the minPerVc-QueueLimit attribute must be at least 88. For VPTs,this attribute does not apply. Regardless of theVpt's service category, standard VPTs always usethe AtmIf CA NrtVbr minPerVcQueueLimit value astheir default.

shapeRecoupPolicy


Domain

Description This attribute specifies the shaping recoup policy forthe rt-VBR service category. This is the policy whichis used to recoup shaping opportunities which arelost when more than one connection schedules acell for the same transmit opportunity. In this case,one connection is scheduled and the cell from theother connection is delayed by one cell time. Thisattribute affects how the transmit time is calculatedfor the next cell on the delayed connection. This at-tribute is ignored if this service category is notshaped. This attribute does not apply to basicVPTs, or standard Vpt VCCs. This attribute is notapplicable and is ignored for 4pOC12SmIrAtm,4pOC12SmLrAtm, and 16pOC3SmIrAtm cards.When the connection which was delayed schedulesthe next cell to transmit, it may calculate the time asa difference from either the previous actual celltransmit time, or the time when the previous cellshould have been transmitted. A value of maxim-umEfficiency results in each connection trying to re-coup or regain any delays in scheduling. The trans-mit time for the next cell is calculated from the timewhen the previous cell should originally have beensent. Cell delay variation (CDV) occurs in this casesince the cells are sent with less than the shapingdelay between them. However, in general theshaper recovers (recoups) lost opportunities andimproves efficiency. A value of minimumCdv resultsin connections not trying to recoup or regain anydelays in scheduling. The transmit time for the nextcell is calculated from the time when the previouscell was actually transmitted. This minimizes CDV,but results in missed cell opportunities.

An override to this default may be specifiedfor a provisioned connection under the Vcd Tm orVpd Tm component. This attribute does not apply tobasic VPTs, or standard Vpt VCCs. A value of dis-abled means traffic shaping cannot be enabled forany rt-VBR connections. For 1pOC12SmLrAtm and1pOC48ChSmIrAtm cards, the value of this attrib-ute must be disabled since traffic shaping is notsupported for rt-VBR connections on these cards.For 3pOC3MmAtm, 3pOC3SmAtm, 3pE3Atm,3pDS3Atm, 3pE1Atm, 3pDS1Atm, 8pE1Atm,8pDS1Atm, and 2pJ6MAtm cards, the value of thisattribute may be enabled only if the interface sup-

If the Vcc Tm, VpcTm, or Vpt Tm, txTrafficDescType attribute indic-ates type 1 or 2, this attribute is ignored and trafficshaping is not applicable for that connection. Avalue of inverseUpc means traffic shaping for aconnection is enabled according to the value of theVcc Tm, Vpc Tm, or Vpt Tm txTrafficDescType at-tribute. A value of inverseUpc when the txTraffic-DescType is 3, 4, or 5, means linear traffic shapingis enabled. Linear traffic shaping uses a single stat-ic traffic shaping rate. A value of inverseUpc whenthe txTrafficDescType is 6, 7, or 8, means inverse-UPC (also referred to as VBR or dual leaky bucket)traffic shaping is enabled. Inverse-UPC traffic shap-ing can burst above the sustained cell rate to thepeak cell rate for the duration defined by the max-imum burst size. Inverse-UPC traffic shaping ex-actly conforms to the requirements of a dual leakybucket UPC enforcer. For 4pOC12SmIrAtm,4pOC12SmLrAtm, and 16pOC3SmIrAtm cards, thevalue inverseUpc is not available.

For the common queue, the discardthresholds are set at approximately 35, 75, and 90percent of the value of this attribute for traffic at dis-card priority 3 (DP=3), DP=2, and DP=1 respect-ively. For 4pOC12SmIrAtm, 4pOC12SmLrAtm, and16pOC3SmIrAtm cards, common queuing is notavailable for the rt-VBR service category. For a per-VC queue, the actual queue length may be reduceddepending on the shaping rate of the connection(for standard Vpt VCCs, this is the shaping rate ofthe Vpt component). The discard thresholds are setat approximately 35, 75, and 90 percent of thescaled queue limit for traffic at discard priority 3(DP=3), DP=2, and DP=1, respectively. However, areduction will never result in a value that is lessthan the value of the minPerVcQueueLimit attribute.The per-VC queue limit may be overridden for aprovisioned connection by specifying a value in theVcd Tm or Vpd Tm txQueueLimit attribute. For1pOC12SmLrAtm and 1pOC48ChSmIrAtm cards,per-VC queues are not available for the rt-VBR ser-vice category.

Description This attribute specifies the default usage parametercontrol (UPC) option for connections of the rt-VBRservice category. This attribute is ignored if the rx-TrafficDescriptorType indicates 1 or 2. An overrideto this default may be specified for a provisionedconnection under the Vcd Tm or Vpd Tm compon-ent. A value of enforced means UPC is enforced foreach connection. When UPC is enforced, non-conforming cells are either tagged or discarded de-pending on the rxTrafficDescriptorType. A value ofmonitored means UPC conformance checking isperformed, except, instead of the non-conformingcells being tagged or discarded, they are merelycounted in the UPC violations counts and passedon unchanged. A value of disabled means UPC isdisabled on the receive path for all rt-VBR connec-tions. This attribute does not apply to basic VPTs,or standard Vpt VCCs. For 3pOC3MmAtm,

weightPolicy


Domain

Description This attribute specifies the policy which is appliedwhen calculating the fairness weight for unshapedconnections of the rt-VBR service category. Thefairness weight for a connection determines the rel-ative amount of bandwidth which that connectionobtains, compared to other connections in the sameservice category. Connections with equal weight getequal transmit opportunities. Connections with high-er weights get more transmit opportunities com-pared with connections that have lower weights. Anoverride to this default may be specified for a provi-sioned connection under the Vcd Tm, or Vpd Tmcomponent. The fairness weight for a connection isdirectly proportional to the value of one of the trafficdescriptor parameters for that connection. This at-tribute specifies which traffic descriptor parameter isused for connections of the rt-VBR service cat-egory. A value of scr means the fairness weight isproportional to the transmit sustained cell rate(SCR) of a connection. Connections with a higherSCR have a higher fairness weight. For connec-tions with txTrafficDescType 3, which have no SCR,the sustained cell rate is assumed to be equal tothe peak cell rate. A value of pcr means the fairnessweight is proportional to the transmit peak cell rate(PCR) of a connection. Connections with a higherPCR have a higher fairness weight. Connectionswith txTrafficDescType 1 or 2 get a minimumweight, which is 1. A value of ecr means the fair-ness weight is proportional to the equivalent cell

237


rate (ECR) of a connection as calculated by con-nection admission control (CAC). Connections witha higher ECR have a higher fairness weight. Con-nections with an ECR of 0 get a minimum weight,which is 1. The weight of a connection is visible inthe Vcc Tm, Vpc Tm, or Vpt Tm weight attribute.This attribute does not apply to basic VPTs andstandard Vpt VCCs. This attribute is ignored if thevalue of the unshapedTransmitQueueing attribute iscommon. This attribute is not applicable and is ig-nored for 3pOC3MmAtm, 3pOC3SmAtm, 3pE3Atm,3pDS3Atm, 3pE1Atm, 3pDS1Atm, 8pE1Atm,8pDS1Atm, 2pJ6MAtm, 1pOC12SmLrAtm, and1pOC48ChSmIrAtm cards.

Description ARtg Pnni CfgNode/<level> SummaryAddress/<address>, <prefixLength>, <reachability> A sum-mary address is an abbreviation of a set of ad-dresses, represented by an address prefix that all ofthe summarized addresses have in common. Asuppressed summary address is used to suppressthe advertisement of addresses which match thisprefix, regardless of scope. The prefixLength spe-cifies the number of significant bits of the address.reachability specifies whether the address is to

vior. The value virtualSourceDest is used to requestthat this connection point function as a virtualsource/virtual destination. The value sourceDest re-quires that this connection point function as a S/Dfor RM cells. S/D mode is automatically invoked atthis connection point either if this is a connectionend point, or if the next hop connection point is con-figured as nonAbrInterworking. The value nonAb-rInterworking is used to request that this connectionpoint function as an interworking between ABR andnon-ABR service categories. This means that thereare no RM cells on the link side of this connection,and that the next hop connection point is performingas an ABR sourceDest. The value abrSwitch isused to request ABR switch behavior for this con-nection point. The ABR switch behavior is first, toconform to virtualSourceDest or nonAbrInterworkingsetting on the next hop, and otherwise to implementABR ER switch behavior. For 3pOC3MmAtm,3pOC3SmAtm, 3pE3Atm, 3pDS3Atm, 3pE1Atm,3pDS1Atm, 8pE1Atm, 8pDS1Atm, and 2pJ6MAtmcards, the only allowable values are sameAsCa,nonAbrInterworking or abrSwitch. If abrSwitch is se-lected, EFCI marking behavior is implemented. For1pOC12SmLrAtm cards, the only allowable valuesare sameAsCa or abrSwitch. If abrSwitch is selec-ted, EFCI marking behavior is implemented. For16pOC3PosAtm and 4pMRPosAtm cards, the onlyallowable value is sameAsCa.

atmServiceCategory


Domain

Description This attribute specifies the ATM service category forboth directions of the connection. The value de-rivedFromBBC may only be used if the Src or Dst

272


component is provisioned under this connection.Otherwise a specific ATM service category must bespecified. A value of derivedFromBBC means theBroadband Bearer Capability (BBC) and bestEffortattributes are used to determine the atmServiceCat-egory of this connection. A value other than de-rivedFromBBC means the value of this attribute isused to override the provisioned BBC InformationElement parameters. In this case, the BBC attrib-utes are not used. The constantBitRate service cat-egory is intended for real-time applications, that isthose requiring tightly constrained delay and delayvariation, as would be appropriate for voice andvideo applications. The consistent availability of afixed quantity of bandwidth is considered appropri-ate for CBR service. Cells which are delayed bey-ond the value specified by Cell Transfer Delay areassumed to be of significantly reduced value to theapplication. The rtVariableBitRate service categoryis intended for real-time applications, that is thoserequiring tightly constrained delay and delay vari-ation, as would be appropriate for voice and videoapplications. Sources are expected to transmit at arate which varies with time. Equivalently, the sourcecan be described as "bursty". Cells which aredelayed beyond the value specified by CTD are as-sumed to be of significantly reduced value to theapplication. Real-time VBR service may supportstatistical multiplexing of real- time sources. ThenrtVariableBitRate service category is intended fornon-real time applications which have bursty trafficcharacteristics and which can be characterized interms of a PCR, SCR, and MBS. For those cellswhich are transferred within the traffic contract, theapplication expects a low cell loss ratio. For all con-nections, it expects a bound on the mean cell trans-fer delay. Non real-time VBR service may supportstatistical multiplexing of connections. The avail-ableBitRate service is an ATM layer service cat-egory for which the limiting ATM layer transfer char-acteristics provided by the network may changesubsequent to connection establishment. ABR ser-vice has a flow control mechanism which supportsseveral types of feedback to control the source ratein response to changing ATM layer transfer charac-teristics. ABR service is not intended to supportreal-time applications. The unspecifiedBitRate ser-vice is intended for non real-time applications; thatis, those not requiring tightly constrained delay anddelay variation. UBR sources are expected to bebursty. UBR service supports a high degree of stat-

273


istical multiplexing among sources. UBR servicedoes not specify traffic related service guarantees.No numerical commitments are made with respectto the cell loss ratio experienced by a UBR connec-tion, or as to the cell transfer delay experienced bycells on the connection.

Description This attribute specifies the bearer capability. Thisattribute is only used for SPVC and SPVP connec-tions. It is one of the Broadband Bearer Capability(BBC) attributes. The purpose of the BBC informa-tion element is to indicate a requested broadbandconnection-oriented bearer service to be providedby the network. The value derivedFromServiceCat-egory specifies that the actual value which is usedfor this connection is derived from the value of theatmServiceCategory. Either, this attribute must beset to derivedFromServiceCategory, or the atmSer-viceCategory attribute must be set to derived-FromBBC, but not both. Class a service is a con-nection-oriented, constant bit rate ATM transportservice. Class a service has end to end timing re-quirements and may require stringent cell loss, celldelay and cell delay variation performance.When ais set, the user is requesting more than an ATMonly service. The network may look at the AAL toprovide interworking based upon its contents. Classc service is a connection-oriented, variable bit rateATM transport service. Class c service has no end-to-end timing requirements. When c is set, the useris requesting more than an ATM only service. Thenetwork interworking function may look at the AALand provide service based on it. Class x service is aconnection-oriented ATM transport service wherethe AAL, trafficType (vbr or cbr) and timing require-

274

rxPacketWiseDiscard

Parameter name rxPacketWiseDiscard

Domain

Description This attribute specifies whether packet-wise discardfunctions are to be enabled or disabled in the re-ceive data direction for this connection. Packet-wisediscard functions apply to AAL5 frame traffic. Thisattribute is not applicable for Vpts. Packet-wisefunctions increase the "goodput" of the link. The re-ceive packet-wise function is Partial Packet Discard(PPD). PPD allows the connection to discard the re-mainder of a cell- forwarded AAL5 frame if one cellof this frame has been discarded, for example dueto UPC. All cells are discarded up to but not includ-ing the EOM cell. The PPD function increases the"goodput" of the link, since cells which are only go-ing to be discarded at the AAL5 reassembly pointare not transmitted. For 1pOC12SmLrAtm cards,this attribute is not applicable and is ignored. For3pOC3MmAtm, 3pOC3SmAtm, 3pE3Atm,3pDS3Atm, 3pE1Atm, 3pDS1Atm, 8pE1Atm,8pDS1Atm, and 2pJ6MAtm cards, PPD is availableat all VCC connection points where UPC may beactivated. PPD is not applicable for Vpcs. Packet-wise discards should only be enabled for connec-tions carrying AAL5 segmentation traffic. Setting thevalue to enabled for any other traffic type may resultin traffic being discarded. PPD is automatically en-abled at frame-to-cell conversion points, independ-ent of the setting of this attribute. For2pOC3MmAtm2, 2pOC3SmAtm2, 2pSTM1eAtm,2pSTM1eCh, 2pSTM1Ch, 4pOC3MmAtm,4pOC3SmIrAtm, 4pDS3ChAtm, 3pDS3Atm2,3pE3Atm2, 12pDS3Atm, 12pE3Atm, and MSA32

cards, this attribute may safely be set to enabled forany connection (Vcc or Vpc) since these FPs havethe ability to automatically detect AAL5-segmentedtraffic on a connection, and only enable packet-wisediscards if AAL5-segmented traffic is detected. For1pOC48ChSmIrAtm cards, this attribute may safelybe set to enabled for VCCs, since these FPs havethe ability to automatically detect AAL5-segmentedtraffic on a connection, and only enable packet-wisediscards if AAL5-segmented traffic is detected. For4pOC12SmIrAtm, 4pOC12SmLrAtm, and16pOC3SmIrAtm cards, packet-wise discard func-tions include EPD and PPD. PPD and EPD apply toindividual VCCs. Packet-wise discard should onlybe enabled for connections carrying AAL5 segment-ation traffic. Setting this attribute to enabled for anyother traffic type may result in all traffic being dis-carded. For 16pOC3PosAtm and 4pMRPosAtmcards, packet-wise discard functions are not avail-able for the receive data direction of a connection.A value of enabled for the rxPacketWiseDiscard at-tribute is used only for signaling SPVC/SPVP setupacross the network, and does not result in enablingpacket-wise discard functions on these cards. PPDand EPD are enabled by default at a connection en-dpoint which is performing AAL5 segmentation andassembly. A value of enabled means packet-wisediscard functions are applied to receive traffic at thisconnection point. A value of disabled means pack-et-wise discard functions are not applied to receivetraffic at this connection point. At a SPVC origin ona PNNI interface, a value of enabled specifies thatframe discard is requested in the forward direction.When this attribute is set to disabled, forward framediscard is not requested in the SPVC call setup.The receive packet-wise discard functions that areactive are visible in the Vcc/Vpc Tm rxPacket-WiseDiscard operational attribute.

If the value of the rxTrafficDescTypeattribute is sameAsTx, the values provisioned in thisattribute are ignored. The traffic parameters for thereceive direction are taken from the txTraffic-DescParm attribute. The values of peak cell rate(PCR), sustained cell rate (SCR), and Minimum CellRate (MCR) are expressed in cell/s. Maximum burstsize (MBS) is expressed in cells. The value of CD-VT is expressed in microseconds. The values ofPCR, SCR, MCR, MBS and CDVT are used for us-age parameter control (UPC). When rxTrafficDesc-Type is 1 or 2, all of the parameters must be set tozero (unused). When rxTrafficDescType is 3, para-meter 1 represents the PCR for CLP equal to 0 and1 traffic; and parameter 4 represents the CDVT.Parameter 1 must be non-zero. Parameters 2 and 3must be set to zero (unused). When rxTrafficDesc-Type is 4, parameter 1 represents the PCR for CLPequal to 0 and 1 traffic; parameter 2 represents thePCR for CLP equal to 0 traffic with cell discard; andparameter 4 represents the CDVT. Parameters 1and 2 must be non-zero. Parameter 3 must be setto zero (unused). Parameter 1 must be greater thanor equal to parameter 2. When rxTrafficDescType is5, parameter 1 represents the PCR for CLP equalto 0 and 1 traffic; parameter 2 represents the PCRfor CLP equal to 0 traffic with cell tagging; and para-meter 4 represents the CDVT. Parameters 1 and 2must be non-zero. Parameter 3 must be set to zero(unused). Parameter 1 must be greater than orequal to parameter 2. When rxTrafficDescType is a6, parameter 1 represents the PCR for CLP equalto 0 and 1 traffic; parameter 2 represents the SCRfor CLP equal to 0 and 1 traffic; parameter 3 repres-ents the MBS for CLP equal to 0 and 1 traffic; andparameter 4 represents the CDVT.

traffic with cell tagging; parameter 3 represents theMBS for CLP equal to 0 traffic; and parameter 4represents the CDVT. Parameter 1, 2 and 3 mustbe non-zero. Parameter 1 must be greater than orequal to parameter 2. When rxTrafficDescType is 9,parameter 1 represents the PCR; parameter 2 rep-resents the CDVT; parameter 3 represents theMCR. Parameter 4 is not used and must be zero.Parameter 1 must be non- zero and must be great-er than or equal to parameter 3. Parameter 3 mayoptionally be zero. If the value of CDVT either inparameter 2 or in parameter 4 is zero, the CDVT istaken from the CA defaults for the particular atm-ServiceCategory of this connection. Parameter 5 ofthe rxTrafficDescParm is always unused. When rx-TrafficDescriptorType is 3 through 8, there are cer-tain extreme combinations of rxTrafficDescParmwhich are outside the capabilities of the UPC hard-ware. The check prov command detects such casesand generates an error message. If this happens,adjust the parameters until they fall within the sup-ported limits. To calculate the limits, use the follow-ing formulae: I1 = 1,000,000,000 / PCR L1 = CDVT* 1000 I2 = 1,000,000,000 / SCR L2 = CDVT +(MBS - 1) * (I2 - I1) Note that I2 and L2 only applywhen the rxTrafficDescriptorType is 6 through 8.For 3pOC3MmAtm, 3pOC3SmAtm, 3pE3Atm,3pDS3Atm, 3pE1Atm, 3pDS1Atm, 8pE1Atm,8pDS1Atm, and 2pJ6MAtm cards, I1 and I2 mustbe less than or equal to 335,523,840. I1 + L1 mustbe less than or equal to 1,342,156,800. I2 + L2must be less than or equal to 1,342,156,800. If thevalues of I1, L1, I2 or L2 are closer to the limits de-scribed above, a further restriction applies. Specific-ally, if either: I1 > 41,940,480 or I2 > 41,940,480 orI1 + L1 > 167,769,600 or I2 + L2 > 167,769,600then both I1 and I2 must be greater than 20,480.For 4pOC12SmIrAtm, 4pOC12SmLrAtm, and16pOC3SmIrAtm cards, L2 must be less than orequal to 2,674,011,406. For 16pOC3PosAtm and4pMRPosAtm cards, L2 must be less than or equalto 17,179,869,180.

txPacketWiseDiscard

285


Parameter name txPacketWiseDiscard

Domain

Description This attribute specifies whether packet-wise discardfunctions are to be enabled or disabled in the trans-mit data direction for this connection. Packet-wisediscard functions apply to AAL5 frame traffic. Thisattribute is not applicable for Vpts. Packet-wisefunctions increase the "goodput" of the link. Thetransmit packet-wise functions are Early PacketDiscard (EPD) and Partial Packet Discard (PPD).EPD allows the connection to discard an entireframe once the transmit queue has reached theEPD threshold. EPD increases the "goodput" of alink, since discarding an entire frame means thatsome queue capacity is guarded for some otherframe which is already partially transmitted. All cellsof the frame are discarded from the Beginning ofMessage (BOM) cell up to and including the End ofMessage (EOM) cell. PPD allows the connection todiscard the remainder of a cell- forwarded AAL5frame if one cell of this frame has been discarded.All cells are discarded up to but not including theEOM cell. The PPD function increases the "good-put" of the link, since cells which are only going tobe discarded at the AAL5 reassembly point are nottransmitted. For 1pOC12SmLrAtm cards, this attrib-ute is not applicable and is ignored.

PPD is not applicable atframe-to- cell conversion points, and is not applic-able for Vpcs. PPD is configured by this attribute.Packet-wise discard should only be enabled forconnections carrying AAL5 segmentation traffic.Setting this attribute to enabled for any other traffictype may result in all traffic being discarded. EPD isautomatically enabled at frame-to-cell conversionpoints, independent of the setting of this attribute.For 2pOC3MmAtm2, 2pOC3SmAtm2,2pSTM1eAtm, 2pSTM1eCh, 2pSTM1Ch,4pOC3MmAtm, 4pOC3SmIrAtm, 4pDS3ChAtm,3pDS3Atm2, 3pE3Atm2, 12pDS3Atm, 12pE3Atm,and MSA32 cards, packet-wise discard functions in-clude EPD and PPD. PPD and EPD apply to indi-vidual VCCs and VCCs within VPCs at all connec-tion points, including tandem VPC connections.Both PPD and EPD are controlled by this attribute.This attribute may safely be set to enabled for any

For4pOC12SmIrAtm, 4pOC12SmLrAtm, and16pOC3SmIrAtm cards, packet-wise discard func-tions include EPD and PPD. PPD and EPD apply toindividual VCCs, as well as VCCs within VPCs atthe VPC termination points, known as VPTs. PPDand EPD do not apply to tandem VPC connectionpoints. Packet-wise discard should only be enabledfor connections carrying AAL5 segmentation traffic.Setting this attribute to enabled for any other traffictype may result in all traffic being discarded.

PPD and EPD ap-ply to individual VCCs, as well as VCCs withinVPCs at the VPC termination points, known asVPTs. PPD and EPD do not apply to tandem VPCconnection points. This attribute may safely be setto enabled for VCCs since these FPs have the abil-ity to automatically detect AAL5-segmented trafficon a connection, and only enable packet-wise dis-cards if AAL5-segmented traffic is detected. A valueof enabled means packet-wise discard functions areapplied to transmit traffic at this connection point. Avalue of disabled means packet-wise discard func-tions are not applied to transmit traffic at this con-nection point. At a SPVC origin on a PNNI interface,a value of enabled specifies that frame discard isrequested in the backward direction. When this at-tribute is set to disabled, backward frame discard isnot requested in the SPVC call setup.

txTrafficDescParm

Parameter name txTrafficDescParm

Domain

Description This attribute is a vector of five traffic parameterswhose meanings are defined by the txTrafficDesc-Type attribute. The values of peak cell rate (PCR),sustained cell rate (SCR), Minimum Cell Rate(MCR) and requested shaping rate are expressedin cell/s. Maximum burst size (MBS) is expressed in

288


cells. CDVT is expressed in microseconds. The val-ues of PCR, SCR, MCR, MBS and CDVT are usedfor connection admission control (CAC). The valueof CDVT is only used for connections where theatmServiceCategory is constantBitRate. For all oth-er values of atmServiceCategory, CDVT is ignored.The values of PCR, SCR, MCR and requestedshaping rate are used to determine the actual shap-ing rate where traffic shaping is enabled. When tx-TrafficDescType is 1 or 2, all of the parametersmust be set to zero. When txTrafficDescType is 3,parameter 1 represents the PCR for CLP equal to 0and 1 traffic; parameter 4 represents the CDVT;and parameter 5 represents the requested shapingrate. A non-zero value in parameter 5 overrides anyvalue in parameter 1. This result is used as thePCR. Parameter 1 must be non-zero. Parameters 2and 3 must be zero. When txTrafficDescType is 4,parameter 1 represents the PCR for CLP equal to 0and 1 traffic with cell discard; parameter 2 repres-ents the PCR for CLP equal to 0 traffic; parameter 4represents the CDVT; and parameter 5 representsthe requested shaping rate. A non-zero value inparameter 5 overrides any value in parameter 1.This result is used as the PCR. Parameter 1 mustbe greater than or equal to parameter 2. Paramet-ers 1 and 2 must be non-zero. Parameter 3 must bezero. When txTrafficDescType is 5, parameter 1represents the PCR for CLP equal to 0 and 1 trafficwith cell tagging; parameter 2 represents the PCRfor CLP equal to 0 traffic; parameter 4 representsthe CDVT; and parameter 5 represents the reques-ted shaping rate. A non-zero value in parameter 5overrides any value in parameter 1. This result isused as the PCR. Parameter 1 must be greaterthan or equal to parameter 2. Parameters 1 and 2must be non-zero. Parameter 3 must be zero.When txTrafficDescType is 6, parameter 1 repres-ents the PCR for CLP equal to 0 and 1 traffic; para-meter 2 represents the SCR for CLP equal to 0 and1 traffic; parameter 3 represents the MBS for CLPequal to 0 and 1 traffic; parameter 4 represents theCDVT; and parameter 5 represents the requestedshaping rate. A non-zero value in parameter 5 over-rides any value in parameter 1. This result is usedas the PCR. Parameters 1, 2 and 3 must be non-zero. Parameter 1 must be greater than or equal toparameter 2. Parameter 5, must either be zero(unused) or greater than or equal to parameter 2.When txTrafficDescType is 7, parameter 1 repres-ents the PCR for CLP equal to 0 and 1 traffic; para-

289


meter 2 represents the SCR for CLP equal to 0 withcell discard; parameter 3 represents the MBS forCLP equal to 0 traffic; parameter 4 represents theCDVT; and parameter 5 represents the requestedshaping rate. A non-zero value in parameter 5 over-rides any value in parameter 1. This result is usedas the PCR. Parameters 1, 2 and 3 must be non-zero. Parameter 1 must be greater than or equal toparameter 2. Parameter 5, must either be zero(unused) or greater than or equal to parameter 2.When txTrafficDescType is 8, parameter 1 repres-ents the PCR for CLP equal to 0 and 1 traffic; para-meter 2 represents the SCR for CLP equal to 0traffic with cell tagging; parameter 3 represents theMBS for CLP equal to 0 traffic; parameter 4 repres-ents the CDVT; and parameter 5 represents the re-quested shaping rate. A non-zero value in paramet-er 5 overrides any value in parameter 1. This resultis used as the PCR. Parameters 1, 2 and 3 must benon-zero. Parameter 1 must be greater than orequal to parameter 2. Parameter 5, must either bezero (unused) or greater than or equal to parameter2. When txTrafficDescType is 9, parameter 1 rep-resents the PCR; parameter 2 represents the CD-VT; parameter 3 represents the MCR; parameter 4and parameter 5 represent are not used and mustbe zero. Parameter 1 must be non-zero and mustbe greater than or equal to parameter 3. Parameter3 may be optionally zero. Whenever it is valid forPCR to be specified, parameter 5 may also be usedto specify a requested shaping rate. A non-zerovalue in parameter 5 overrides the value in para-meter 1 and is used as the peak cell rate in calcula-tions of CAC and shaping rate. When the atmSer-viceCategory is availableBitRate (ABR), the shap-ing rate is dynamically chosen, based on the ABRflow control mechanism, as a value between theMCR and the PCR or the requested shaping rate ifapplicable. For txTrafficDescType 3, 4 and 5, thetransmit traffic is shaped at the next available shap-ing rate less than the PCR. For txTrafficDescType6, 7 and 8 if linear traffic shaping is selected, thetransmit traffic is shaped at the highest availablerate which is between PCR and SCR. However, ifthere is no available shaping rate between PCRand SCR, traffic is shaped at the next rate abovethe PCR. For txTrafficDescType 3 ,4,5,6,7 and 8,with 16pOC3PosAtm and 4pMRPosAtm cards,parameter 4 must be less than or equal to 643,000.For txTrafficDescType 6, 7 and 8 if inverse-UPCtraffic shaping is selected, the transmit traffic is

Parameter name txWredMode

Domain

Description This attribute specifies the activation of weightedrandom early detection (WRED) functionality.WRED is considered a packet- wise discard func-tion and as such applies only to AAL5 frame traffic.WRED is applied in the transmit direction for thisconnection. WRED function should be enabled onlyfor connections which are transferring TCP/IPtraffic. WRED acts to prevent synchronization ofmultiple TCP/IP sources by randomly discarding asmall percentage of frames when transmit queuecongestion reaches the designated level. WREDmay also be used to differentiate service on VCC's

291


by preferentially discarding one VCC before anoth-er. Discards start at 0% of cells, when the queue ispart-way to the Early Packet Discard (EPD)threshold, and rise to 100% of cells discarded at theEPD threshold. WRED discards all the cells in aframe. A value of enabled means WRED is enabledfor all applications linked to the given Vcc. A valueof perFlow means each TCP application has indi-vidual control over whether to enable or disableWRED. If the value of the txPacketWiseDiscard at-tribute is disabled, or if the value of this attribute isdisabled, WRED functionality is disabled.

Description This attribute specifies whether this connection en-ables usage parameter control (UPC) when receiv-ing traffic from the ATM interface. The valuesameAsCa means UPC for the connection is basedon the value of the usageParameterControl attributeof the service category component under the AtmIfCA. If the service category has UPC enforced ormonitored, then UPC is enabled on the connection.The value disabled means UPC for this connectionis disabled regardless of the provisioning of the ser-vice category. The value enforced means UPC forthis connection is enforced regardless of the provi-sioning of the service category. When UPC is en-forced, non-conforming cells are either tagged ordiscarded depending on the rxTrafficDescriptor-Type. The value monitored means UPC for thisconnection is monitored regardless of the provision-ing of the service category. When UPC is mon-itored, instead of the non-conforming cells beingtagged or discarded, they are merely counted in theUPC violations counts and passed on unchanged.Note that setting UPC to enforced or monitored mayhave no effect under certain cases.

If the address is a single wild-card, thenthat indicates that the interface supports all ad-dresses. If there is no better match, then this inter-face may be chosen in the routing. If there is morethan one interface with a single wild-card static ad-dress, then the choice is made using a round robinalgorithm. The round robin algorithm first tries theprimary routes. If none of the primary routes suc-ceed, then the alternate routes are tried. Note thatthe UniInfo and PnniInfo sub-components are mutu-ally exclusive.

Domain

Description This attribute specifies the minimum queue limit forthe per-VC queues of connections of the UBR ser-vice category. This attribute is ignored for1pOC12SmLrAtm cards, because they do not sup-port per-VC queues for the UBR service category.The queue limit of a per-VC queue is obtained byscaling down the txQueueLimit attribute based onthe shaping rate of that queue (shaping rate for theconnection and for standard Vpt VCCs, the shapingrate of the Vpt). This produces a constant delay forvarious queue lengths. The value of thetxQueueLimit attribute provides an upper boundwhile the value of the minPerVcQueueLimit attributeprovides the lower bound. The value of this attributemust not be greater than the value of thetxQueueLimit attribute. If this service category isused by Trunks the value of the minPerVc-QueueLimit attribute must be at least 88. For VPTs,this attribute does not apply. Regardless of Vpt'sservice category, standard VPTs always use the At-mIf CA NrtVbr minPerVcQueueLimit value as theirdefault. To determine the queue limit of a standardVpt Vcc, the txQueueLimit attribute is scaled downby the Vpt shaping rate. For 3pOC3MmAtm,3pOC3SmAtm, 3pE3Atm, 3pDS3Atm, 3pE1Atm,3pDS1Atm, 8pE1Atm, 8pDS1Atm, and 2pJ6MAtmcards, this attribute must be set to the same valuefor CA NrtVbr, Abr, and Ubr components.

shapeRecoupPolicy


Domain

Description This attribute specifies the shaping recoup policy forthe UBR service category. This is the policy whichis used to recoup shaping opportunities which arelost when more than one connection schedules acell for the same transmit opportunity. In this case,one connection is scheduled and the cell from theother connection is delayed by one cell time. Thisattribute affects how the transmit time is calculatedfor the next cell on the delayed connection. This at-tribute is ignored if this service category is notshaped. This attribute does not apply to basicVPTs, or standard Vpt VCCs. This attribute is notapplicable and is ignored for 4pOC12SmIrAtm,4pOC12SmLrAtm, and 16pOC3SmIrAtm cards.When the connection which was delayed schedulesthe next cell to transmit, it may calculate the time asa difference from either the previous actual celltransmit time, or the time when the previous cellshould have been transmitted. A value of maxim-umEfficiency results in each connection trying to re-coup or regain any delays in scheduling. The trans-mit time for the next cell is calculated from the time

316


when the previous cell should originally have beensent. Cell delay variation (CDV) occurs in this casesince the cells are sent with less than the shapingdelay between them. However, in general theshaper recovers (recoups) lost opportunities andimproves efficiency. A value of minimumCdv resultsin connections not trying to recoup or regain anydelays in scheduling. The transmit time for the nextcell is calculated from the time when the previouscell was actually transmitted. This minimizes CDV,but results in missed cell opportunities.

This attribute does not apply to ba-sic VPTs, or standard Vpt VCCs. A value of dis-abled means traffic shaping cannot be enabled forany UBR connections. For 1pOC12SmLrAtm and1pOC48ChSmIrAtm cards, the value of this attrib-ute must be disabled since traffic shaping is notsupported for UBR connections on these cards. For3pOC3MmAtm, 3pOC3SmAtm, 3pE3Atm,3pDS3Atm, 3pE1Atm, 3pDS1Atm, 8pE1Atm,8pDS1Atm, and 2pJ6MAtm cards, the value of thisattribute may be enabled only if the interface sup-ports shaping, as defined by the perVcQueueInter-faces attribute of the Lp Eng Arc Cqc Ov compon-ent. If that component does not exist, the value ofthis attribute must be disabled. If the Vcc Tm, VpcTm, or Vpt Tm txTrafficDescType attribute indicatestype 1 or 2, this attribute is ignored and traffic shap-ing is not applicable for that connection. A value ofinverseUpc means traffic shaping for a connectionis enabled according to the value of the Vcc Tm,Vpc Tm, or Vpt Tm txTrafficDescType. A value ofinverseUpc when the txTrafficDescType is 3, 4, 5,or 9 (for UBR with MDCR connections), means lin-ear traffic shaping is enabled. Linear traffic shapinguses a single static traffic shaping rate. A value ofinverseUpc when the txTrafficDescType is 6, 7, or8, means inverse-UPC (also referred to as VBR ordual leaky bucket) traffic shaping is enabled. In-verse-UPC traffic shaping can burst above the sus-tained cell rate to the peak cell rate for the durationdefined by maximum burst size. Inverse-UPC trafficshaping exactly conforms to the requirements of adual leaky bucket UPC enforcer. For4pOC12SmIrAtm, 4pOC12SmLrAtm, and16pOC3SmIrAtm cards, the value inverseUpc is notavailable. For 3pOC3MmAtm, 3pOC3SmAtm,3pE3Atm, 3pDS3Atm, 3pE1Atm, 3pDS1Atm,8pE1Atm, 8pDS1Atm, and 2pJ6MAtm cards, thevalue inverseUpc is not supported and is equivalentto the value enabled. A value of enabled when thetxTrafficDescType is 3, 4, 5, 6, 7, 8, or 9 (for UBRwith MDCR connections), means traffic shaping fora connection is enabled using linear shaping.

Description This attribute specifies the default maximum queuelength for the emission queues used to buffer thetraffic of the UBR service category. It is used as thebasis for setting both the queue length and the dis-card thresholds on both common and per-VCqueues. For the common queue, the discardthresholds are set at approximately 35, 75, and 90percent of the value of this attribute for traffic at dis-card priority 3 (DP=3), DP=2, and DP=1 respect-ively. For 4pOC12SmIrAtm, 4pOC12SmLrAtm, and16pOC3SmIrAtm cards, common queuing is not

320


available for the UBR service category. For a per-VC queue, the actual queue length may be reduceddepending on the shaping rate of the connection(for standard Vpt VCCs, this is the shaping rate ofthe Vpt). The discard thresholds are set at approx-imately 35, 75, and 90 percent of the scaled queuelimit for traffic at discard priority 3 (DP=3), DP=2,and DP=1 respectively. However, a reduction willnever result in a value that is less than the value ofthe minPerVcQueueLimit attribute. The per- VCqueue limit may be overridden for a provisionedconnection by specifying a value in the Vcd Tm orVpd Tm txQueueLimit attribute. For1pOC12SmLrAtm and 1pOC48ChSmIrAtm cards,per-VC queues are not available for the UBR ser-vice category. For 1pOC48ChSmIrAtm cards, thisattribute is used to set the maximum size of the link-class queue for buffering the egress traffic of theUBR service category. This is similar to commonqueuing, except that each UBR connection main-tains a per-VC utilization limit of the common queuespecified for a provisioned connection by the VcdTm or Vpd Tm txQueueLimit attribute. A value ofautoConfigure means an appropriate value is selec-ted based on the card type. For 3pE1Atm,3pDS1Atm, 8pE1Atm, 8pDS1Atm, 2pJ6MAtm,2pSTM1eCh, 2pSTM1Ch and 4pDS3ChAtm cards,the value is 1792.

The fairness weight for a connection isdirectly proportional to the value of one of the trafficdescriptor parameters for that connection. This at-tribute specifies which traffic descriptor parameter isused for connections of the UBR service category.A value of mcr means the fairness weight is propor-tional to the default minimum cell rate (MCR) forUBR connections. If the default minimum cell rate is0, all UBR connections get a minimum weight,which is 1. A value of pcr means the fairness weightis proportional to the transmit peak cell rate (PCR)of a connection. Connections with a higher PCRhave a higher fairness weight. Connections with tx-TrafficDescType 1 or 2 get a minimum weight,which is 1. A value of ecr means the fairness weightis proportional to the equivalent cell rate (ECR) of aconnection as calculated by connection admissioncontrol (CAC). Connections with a higher ECR havea higher fairness weight. Connections with an ECRof 0 get a minimum weight, which is 1. The weightof a connection is visible in the Vcc Tm, Vpc Tm, orVpt Tm weight attribute. This attribute does not ap-ply to basic VPTs and standard Vpt VCCs.

This attributeis used by the Connection Admission Control (CAC)algorithm to compute the equivalent cell rate (ECR)required for CBR connections. There is a trade-offbetween the service category CLR and the achiev-able Vpt bandwidth utilization. To guarantee an ex-cellent service category, the CLR should be assmall as possible (for example, 1E-10). However, asmaller CLR results in a larger equivalent cell ratefor a given connection and hence a lower Vpt band-width utilization. A value of anyClrValue means thatno bandwidth is reserved for CBR connections, andCAC is effectively turned off. All CBR connectionsare admitted.

timeslotDataRate

Parameter name timeslotDataRate

Domain

Description This attribute selects the data rate of the timeslotsin a channel of a DS1 component. For E1, the datarate of the timeslots will always be 64kbit/s regard-less of this attribute. When doNotOverride is selec-ted for a channel on a DS1, the data rate of thechannel's timeslots are dependant on the zeroCod-ing selection of the DS1 component. If the zeroCod-ing is B8ZS (where supported on the FP) or none,the timeslot's data rate will be 64kbit/s. If the zero-Coding option is bit7Stuffing, the data rate of atimeslot will be 56kbit/s. When 56k is selected for achannel on a DS1, the least significant bit of eachtimeslot of this Channel will always be set to 1 andnot used for data. The data rate for the timeslots ofthis channel is therefore restricted to 56kbit/s. Onthe 4pDS3Ch cards, the zeroCoding attribute is re-stricted to the value none, and so when thetimeslotDataRate is set to doNotOverride, thetimeslot's data rate will be 64kbit/s. Timeslot datarate of 56k is also available on this card. On the4pDS3ChAal1 card, the only allowed value for thisattribute is doNotOverride. One application of thisattribute is to allow a DS1 line to support mixingchannels that originate from lines that use differentzeroCoding schemes.

clockingSource

Parameter name clockingSource

Domain

Description This attribute specifies the source of the transmitclock for the DS1 tributary. When the clockingsource is local, the crystal on the port generates theclocking for the DS1 tributary. When the clockingsource is line, the port synchronizes to the clockfrom the DS1 tributary. When the clocking source ismodule, the port's clock synchronizes to the clockprovided by the oscillator on the active CP. Whenthe clocking source is sameAsDs3, the Ds1 port'sclock synchronizes to the same clock source as thatof its parent Ds3 port. On a 1pDS3C card, if theNetworkSynchronization (NS) component ispresent, the default value of this attribute will bemodule; otherwise it will be line. On a 2pDS3cAalcard, the only valid values are local and module. Ifthe NS component is present, the default value ofthis attribute will be module; otherwise it will be loc-al. On the 4pDS3Ch, 4pDS3ChAtm, and4pDS3ChAal1 cards, the only valid value issameAsDs3. This is because a DS1 must have thesame clocking source as its parent DS3.

Note that the multi-port cell-basedcards have one common clock source for all ports.For this reason, the following rules apply for thevalue of clockingSource across the board's threeports: All three clockingSource values must be "loc-al" OR All three clockingSource values must be"module" OR One clockingSource value must be"line" and the other two must be "otherPort". If thereis no NS component provisioned, the default valuefor this attribute will be local. If the NS componenthas been provisioned, the default value is module,except for the 1pDS3C cards. For the 1pDS3Ccards, the default and only valid value for this attrib-ute is local. The clockingSource of the DS1 sub-component becomes the effective clocking sourcefor this attribute.

Parameters:

lnnConnectionPoolCapacity

Parameter name lnnConnectionPoolCapacity

Domain

Description This attribute indicates the maximum number of re-source records for the connections which utilize Lo-gical Network Number (LNN) on the LogicalPro-cessor. A logical network is a subset of nodes to-gether with a subset of trunks that interconnectthose nodes. It carries the traffic for a defined set ofnetwork protocols. An LNN is used to identify a lo-gical network. The connectionless services that util-ize the logical networks require some processing atthe intermediate nodes. This pool is allocated at theintermediate nodes to sustain these connectionlessservices. If the McsMgr DprsMcsEpG/n Ep/n EpDtransportConnectionPreference attribute is set to at-

404


mOnly, each instance of the McsMgr DprsMcsEpG/n Ep/n component uses one resource record fromthis pool, otherwise it does not use this pool. Note:Frame and Cell queues also compete for thismemory. Each DPRS instance requires two re-source records from this pool. The maximum size ofthis pool is 256 for CQC based cards. The defaultcardDependent has the effect of setting lnnConnec-tionPoolCapacity to 128 for CQC cards and 256 forSGAF cards.

subConnectionPoolCapacity

Parameter name subConnectionPoolCapacity

Domain

Description This attribute indicates the maximum number ofsub-connections for the LogicalProcessor. A sub-connection is used for interworking the ATM ser-vices with the frame oriented services such asFrame Relay and Path Oriented Routing System(PORS). When a frame is received at a sub- con-nection, the frame header is modified to be compat-ible with the service it is to be forwarded to. Due tolimited resources, not all of the sub-connections re-quested by this attribute may be allocated. The de-sired number of sub- connections allocated is indic-ated by the sum of fcrc subConnectionPoolAvail-able and fcrc subConnectionPoolUsage attributes.This pool is used for connection oriented servicesonly. Each of the following services uses one ormore sub-connections from this pool: Any FrameRelay DLCI (provisioned [permanent] or signalled(SVC))[FRUNI, FRNNI, FRATM, BNX, IP Optim-ized] Any PORS LCN Any MPLS connection Whenthe sub-connection pool is exhausted, no more con-nections are accepted from the services which util-ize this pool. Note: Ip Routing entries also competefor this memory. The maximum size of this pool is8192 for CQC based cards. The default cardDe-pendent has the effect of setting subConnection-PoolCapacity to 1024 for both CQC cards and

Generally, a numericallyhigher value of scheduling class (lower value ofemission priority) indicates the packet is less likelyto be delayed. This traffic is considered more urgentand less delay tolerant. A numerically lower value ofscheduling class (higher value of emission priority)indicates the packet is more likely to be delayed.This traffic is considered less urgent and more

This attribute also spe-cifies which bits are examined when TosMap com-ponents are used for IP packet classification. By de-fault, this attribute is set to the value of hex FC tocorrespond to the six bits of the Differentiated Ser-vices Code Point (DSCP) field. The tosMask attrib-ute in all EgressCosTreatment components underthe same CosPolicyGroup must be set to the samevalue. A warning is issued if tosMask is set to any

discardPriority

Parameter name discardPriority

Domain

Description This attribute specifies the drop precedence as-signed to an IP packet when the Class of Service(CoS) assigned to the packet is equal to the in-stance value of the IngressCosTreatment compon-ent. Attribute values low, medium, and high indicatethe packet is assigned drop precedence accord-ingly. A value of unchanged indicates the drop pre-cedence assigned to the packet is not modified. Itremains at the value provided by the ingress con-nection. A drop precedence is assigned to a packetto control its loss sensitivity relative to other packetswhen the packets are placed into the same queue.Generally, the low value indicates the packet is lesslikely to be discarded when the queue is congested.This traffic has a higher probability of being forwar-ded. The high value indicates the packet is morelikely to be discarded when the queue is congested.This traffic has a lower probability of being forwar-ded. The actual loss sensitivity of packets dependson the discarding mechanism at the queue. A warn-ing is issued if the discardPriority attribute of one ormore, but not all, of the IngressCosTreatment sub-components the CosPolicyGroup is set to un-changed. Another warning is issued if the dis-cardPriority attribute of two IngressCosTreatmentsubcomponents with the same instance value underany two CosPolicyGroup subcomponents of the VrIp are not equal. This applies only to those In-gressCosTreatment subcomponents where the dis-cardPriority attribute is not set to unchanged. If thisrule is violated, then the Class of Service (CoS) todrop precedence mapping will not be consistent atall IpPorts on the Vr. See the description of theCosPolicyGroup for more information.

Parameters:

rdnId


Domain

Description Vr/<string> Ip Pg/<string> Policy/<string> IpAd-drLayer4Flow/n The IpAddrLayer4Flow componentis used to specify Multifield (MF) criteria for assign-ing Class of Service (CoS) values to IP packets.The IP packet is checked to see if it matches thecriteria specified by each IpAddrLayer4Flow com-ponent, if any, under the CosPolicyGroup compon-ent. The CoS assigned to the packet is the value ofthe assignedCos attribute on the parent Policy com-ponent of the IpAddrLayer4Flow whose criteria best

450


match the packet. For example, to assign Class ofService (CoS) value 1 to FTP packets destined tosubnet 123.123.123.0, an IpAddrLayer4Flow sub-component is added to the Policy component wherethe assignedCos attribute is set to 1. The prefix,prefixLength, protocol, and portNumberRange at-tributes of the IpAddrLayer4Flow component are setto 123.123.123.0, 24, tcp, and 20, 21, respectively.This criteria also applies to each FTP packet thatoriginates from subnet 123.123.123.0, but only ifthe source address and port number of the packetdo not match any IpAddrLayer4Flow subcompon-ents of the CosPolicyGroup. Multifield classificationoverrides Behavior Aggregate (BA) classification.This means that BA classification, which is con-trolled by TosMap components, is performed only ifthe packet does not match any IpAddrLayer4Flowcomponent. The packet matching algorithm for MFclassification is explained in more detail as follows.A match can be found only if the IP header protocolfield is one of ICMP, TCP, or UDP. The prefix, pre-fixLength, and portNumberRange attributes arechecked only if the protocol field in the header isTCP or UDP. The destination IP address and des-tination port number information from the packet isfirst compared against the prefix attribute in con-junction with the prefixLength and portNumber-Range attributes. If the prefixLength is 0 and theprefix is 0.0.0.0, then any value in the packet's IPdestination address fields is a match. If portNum-berRange is 0, then any value in the packet's des-tination port number fields is a match. If more thanone IpAddrLayer4Flow component matches a pack-et (for instance one component specifies a range ofIP addresses and a second specifies a single IP ad-dress in the range), then the component with themore precise match is used (the one which spe-cifies the single address in this case). Precedenceis always given to the IP address over the port num-ber. For example, if one IpAddrLayer4Flow com-ponent specifies an range of IP addresses that in-cludes the IP address from the packet and any portnumber, while a second IpAddrLayer4Flow com-ponent specifies an exact port number but a widerrange of addresses, the first IpAddrLayer4Flowcomponent is used. If no match is found using thepacket's destination IP address and destination portnumber information, then a second search is per-formed using the packet's source IP address andsource port number information. This means that anIpAddrLayer4Flow component where the protocol is

451


udp or tcp, the prefixLength is 0 and the portNum-berRange is 0, always matches some destinationaddress and port number. This prevents the sourceaddress and port number check from being per-formed. An ICMP packet matches any IpAddrLay-er4Flow component whose protocol attribute is setto icmp. No attempt is made to match any packetswhere the options or fragment bits are set.

rfc1058MetricUsage

Parameter name rfc1058MetricUsage

Domain

Description This attribute determines the metric usage for thisRIP instance. This flag is used to determine the waymetrics are incremented. RFC 1058 way: SendingUpdate: This is to use the metric for the route fromthe routing table as the advertised metric to be sentfor that route. Nothing is ever added to this valuefrom the sending side. The only special case hand-ling is that if the route being advertised is the net-work route of a directly connected network, the met-ric in the routing table will be zero. Then the RipIfinterface metric for the interface being advertised isused as the advertise metric. If the interface beingadvertised is not a Rip interface, then metric valueof 1 is used. Receiving Update: Add receiving inter-face's RIP metric to the metric for the route in thereceived advertisement and install the result in thereceiver's routing table as the metric for that route.Older way: Sending Updates: Add the out going in-terfaces rip metric to the metric for a route in therouting table to form the metric to be advertised forthat route. Receiving Updates: The metric receivedin the advertisement for a route is put directly in therouting table as the metric for that route. Note: It is

481


recommended that, all the routers in this autonom-ous system should be following the rfc1058 metricsystem. Setting this flag to disabled will have the ef-fect of running the RIP with old metric incrementingsystem.

Parameters:

rdnId


Domain

Description Vr/<string> Ip CosPolicyGroup/<string> This com-ponent and its subcomponents specify the IP Classof Service (CoS) capabilities of an IpPort. Up to fourdifferent forwarding and packet marking behaviorscan be configured. For a greater range of forward-ing and packet marking behaviors, the Differenti-ated Services capabilities of the Vr Differentiated-ServicesDomain and Vr Ip DiffServProfile compon-ents is used. See the descriptions of those compon-ents for more information. A CosPolicyGroup com-

537


ponent is used by all IpPort subcomponents of aVirtualRouter by setting the cosPolicyAssignmentattribute of the Ip component. It is used by one ormore IpPort subcomponents directly by setting thecosPolicyAssignment attribute of the IpPort. Thedirect assignment to the IpPort completely overridesthe assignment to the Ip. Processing of IP packetswith CosPolicyGroup components is based on aClass Of Service (CoS) value assigned to each IPpacket as it processed by the VirtualRouter. CoSvalues vary over the range from 0 to 3 and havelocal significance only. There are six logical stagesin CoS processing on the VirtualRouter. These sixstages are presented below, along with the behavi-or of locally generated packets, and the behavior ofany IpPort that does not use a CosPolicyGroup,and exceptions for MS3 cards. 1. INGRESS CLAS-SIFICATION AND CoS ASSIGNMENT The ClassOf Service (CoS) value assigned to an IP packet isinitialized to be equal to the connection class valueassociated with the ingress Layer 2 connectionwhere the packet was received. For AtmMpe, theconnection class is specified by the ipCos attributeof the AtmConnection subcomponent. For FrDte,the connection class is specified by the ipCoS at-tribute of the StaticDlci or DynamicDlciDef subcom-ponent. For IpDlciGroup, the connection class isspecified by the ipCos attribute of the FrConnectionsubcomponent. For all other media, the connectionclass is specified by the ipCoS attribute of the Ip-Port. After classification is performed as describedabove, if one or more TosMap components existunder a Policy subcomponent of the CosPolicy-Group used by the IpPort where the packet was re-ceived, then the Class Of Service (CoS) assignedto the packet is updated according to these com-ponents if there is a match. A match occurs if selec-ted bits of the Differentiated Services (DS) field,also known at the Type of Service (ToS) field, areequal to the same selected bits of one of the valuesspecified by the tos attribute of a TosMap subcom-ponent of the CosPolicyGroup used by the IpPortwhere the packet was received. If a match occurs,then the CoS value assigned to the packet is setequal to the value of the assignedCos attribute ofthe parent Policy of the TosMap where the matchoccurred. If one or more IpAddrLayer4Flow sub-components exist under a Policy subcomponent ofthe CosPolicyGroup used by the IpPort where thepacket was received, then the Class Of Service(CoS) assigned to the packet is updated according

538


to these components if there is a match. This over-rides any prior CoS assignment. 2. DROP PRE-CEDENCE ASSIGNMENT The packet is assigneda logical drop precedence value according to the In-gressCosTreatment subcomponents of the CosPoli-cyGroup used by the IpPort where the packet wasreceived. The drop precedence is obtained fromdiscardPriority attribute of the IngressCosTreatmentcomponent whose instance value matches theClass Of Service (CoS) value currently assigned tothe packet. If the selected IngressCosTreatmentdiscardPriority attribute specifies low, medium, orhigh, then a drop precedence is assigned accord-ingly. If the selected IngressCosTreatment specifiesunchanged, then the drop precedence assigned tothe packet is not modified. A drop precedence is as-signed to a packet to control its loss sensitivity relat-ive to other packets when the packets are placedinto the same queue, as explained in Step 6. Gen-erally, the low value indicates the packet is lesslikely to be discarded when the queue is congested.This traffic has a higher probability of being forwar-ded. The high value indicates the packet is morelikely to be discarded when the queue is congested.This traffic has a lower probability of being forwar-ded. The actual loss sensitivity of packets dependson the discarding mechanism at the queue. 3.SCHEDULING CLASS ASSIGNMENT The packetis assigned a scheduling class value for eight, four,three, and two queues in the range from 0 to 7, 0 to3, 0 to 2, and 0 to 1, respectively. These values arederived from the emissionPriority attribute of theEgressCosTreatment subcomponents of theCosPolicyGroup used by the IpPort where the pack-et is transmitted. The emissionPriority attribute ofthe EgressCosTreatment subcomponent whose in-stance value matches the Class Of Service (CoS)value assigned to the packet is used. The emis-sionPriority attribute of the EgressCosTreatmentcomponent is mapped to scheduling classes ac-cording to the following table: --------------------------------------------------------------------------Emission Scheduling Class Priority 8 Queues4Queues 3Queues 2 Queues ----

539


----------------------------------------------------------------------1 5 3 2 1 2 4 2 1 0 3 2 1 0 0 4 0 0 0 0 5 0 0 0 0 6 00 0 0 7 0 0 0 0 8 0 0 0 0 Scheduling classes are as-signed to a packet to control its scheduling behaviorrelative to other packets at the egress interfacewhere the packets are transmitted, as explained inStep 6. Generally, a numerically higher value ofscheduling class (lower value of emission priority)indicates the packet is less likely to be delayed.This traffic is considered more urgent and lessdelay tolerant. A numerically lower value ofscheduling class (higher value of emission priority)indicates the packet is more likely to be delayed.This traffic is considered less urgent and moredelay tolerant. The actual scheduling behavior ofpackets depends on the scheduling mechanism andnumber of queues at the egress interface. 4.EGRESS DSCP MARKING The DSCP field of thepacket is marked according to the EgressCosTreat-ment subcomponents of the CosPolicyGroup usedby the IpPort where the packet is transmitted. TheDSCP value is obtained from tos attribute of theEgressCosTreatment component whose instancevalue matches the Class Of Service (CoS) valuecurrently assigned to the packet. The new value ofthe DSCP field does not influence the forwardingbehavior of the packet as it continues to be pro-cessed by the VirtualRouter, but it may have signi-ficance at the next hop. 5. MULTI-CONNECTIONCONGESTION CONTROL The CoS assigned tothe packet is used to select one of up to four Layer2 connections at the IpPort where the packet istransmitted. Per-packet selection of egress connec-tions is supported only if these conditions are alltrue: i) the egress media is FrDte, AtmMpe, IpDlciG-roup, and ii) more than one Layer 2 connection isconfigured to the next hop IP router, and iii) eachconnection is provisioned with a different connec-tion class. Normally the packet is transmitted on theconnection whose connection class is equal to theCoS assigned to the packet. If that connection doesnot exist, then the connection having the next lowerconnection class is used. If that connection doesnot exist also, then the connection having the nexthigher connection class is used. For AtmMpe theconnection class is specified by the ipCos attributeof the AtmConnection subcomponent. For FrDte theconnection class is specified by the ipCoS attributeof the StaticDlci and DynamicDlciDef subcompon-ents. For IpDlciGroup the connection class is spe-

540


cified by the ipCos attribute of the FrConnectionsubcomponent. If each Layer 2 connection is con-figured to provide different policing and schedulingcharacteristics, then the forwarding behaviors of IPpackets are differentiated as they transit throughthe Layer 2 network. In general, the schedulingcharacteristics of the connections should be con-figured to be better for numerically greater connec-tion class values. For example, if four AtmConnec-tion components are associated with AtmIf compon-ents configured for ATM service classes UBR,nrtVBR, rtVBR, and CBR, then the ipCos attributesof the AtmConnection components should be either0, 1, 2 and 3, respectively, or 0, 1, 3 and 2 respect-ively. 6. SINGLE-CONNECTION CONGESTIONCONTROL The drop precedence and schedulingclasses assigned to the packet are used by theegress interface where the packet is transmitted,but only if the egress interface supports these para-meters on a per- connection basis. Multiple dropprecedences are supported on GQM cards at Atm-Mpe interfaces. On FQM interfaces they are sup-ported at Gigabit Ethernet interfaces. On PQCcards with AQM they are supported at AtmMpe,FrDte, IpDlciGroup, and Ethernet interfaces. OnPQC cards with APC the drop precedence of apacket is controlled by the outgoing ATM CLP orFrame Relay DE bit which is determined by by thedrop precedence of the PHB and the Layer 2 con-figuration. On CQC cards multiple drop preced-ences are supported at AtmMpe interfaces. OnSBIC cards they are supported at PPP and FrDteinterfaces. Eight queues per connection are suppor-ted on FQM cards at Gigabit ethernet interfaces.Four queues per connection are supported on PQCcards at PPP interfaces, at FrDte interfaces provi-sioned with DirectConnection, and at IpDlciGroupand IpoDlci interfaces where FRF.12 is disabled onthe DLCI. Two queues per connection are suppor-ted on SBIC cards at PPP and FrDte interfaces.Only one queue per connection is supported onATM interfaces. This implies that multi-connectioncongestion control must be used to provide shedul-ing differentiation at ATM interfaces. LOCALLYGENERATED PACKETS Ingress classification isnot performed on packets generated locally at theVirtualRouter. For a locally generated packet thatused for network control the assigned Class Of Ser-vice (CoS) value and the assigned drop preced-ence, is initialized to 3 and low respectively. For anyother locally generated packet, these values are ini-

541


tialized to 0 and medium respectively. For a locallygenerated ICMP echo request packet, the assignedCoS is overridden by the -cos option of the Pingcommand. For a locally generated ICMP echo replypacket, the assigned CoS is set equal to the as-signed CoS of the received request packet. TheDSCP field of locally generated packets that usedfor network control is always initialized to 48. TheDSCP field of other packets is always initialized to0. For a locally generated ICMP echo request pack-et, the initial value of the DSCP field is overriddenby the -tos or -dscp option of the Ping command.For a locally generated ICMP echo reply packet, theDSCP field is set to the value contained in the IPheader of the received request packet. Locally gen-erated IP multicast and IP broadcast packets arenot subject to Multi-Connection Congestion Controlas described above. Each of these packets iscopied and transmitted individually on each of theavailable connections. DEFAULT BEHAVIOR TheIP CoS behavior of any IpPort that does not use aCosPolicyGroup (by setting the cosPolicyAssign-ment attribute of the Ip or IpPort as explainedabove) is identical to an IpPort that uses theCosPolicyGroup described here: There are noPolicy subcomponents. There are four In-gressCosTreatment subcomponents with instancevalues 0, 1, 2, 3 where the discardPriority attributeof each instance is set to unchanged. There arefour EgressCosTreatment subcomponents with in-stance values 0, 1, 2, 3 where the emissionPriority,setTosByte, tos, and tosMask attributes of each in-stance are set to 4, no, 0, and hexadecimal FC, re-spectively. EXCEPTIONS FOR GQM-BASED andFQM_BASED CARDS The use of the CosPolicy-Group component at interfaces on a VirtualRouterthat does not have a DifferentiatedServicesDomainsubcomponent also applies as described above toGigabit Ethernet on FQM-based cards and AtmMpeinterfaces on GQM-based cards, with the followingsix exceptions: 1) The TosMap and IpAddrLay-er4Flow components are always ignored at an in-gress interface on one of these cards. 2) An IPpacket received on a Gigabit Ethernet interface isalways assigned high drop precedence. 3) An IPpacket received on a ATM interface on one of thesecards is always assigned unchanged drop preced-ence. 4) An IP packet received at an ingress inter-face on one of these cards is always assignedscheduling class 0. 5) An IP packet transmitted ategress Gigabit Ethernet interface is always as-

542


signed scheduling class 0. 6) An IP packet receivedat an ingress interface on one of these cards is isnot eligible for egress DSCP marking at any inter-face.

546


routes to block or send, but rather the metric valueadvertised for the routes. A value of 0 indicates thatthe exported routes will be advertised with their ori-ginal metric. When exporting routes from other pro-tocols into RIP, an exportMetric value of 0 will dis-tribute these routes with the metric of the originalprotocol. If the metric of the original protocol ex-ceeds 15, the exported routes will be considered asunreachable by RIP. If an exportMetric value of 16is specified, the exported routes will be advertisedinto RIP as unreachable.

This value is used to select acongestion threshold when the packet is placed ona queue that supports multiple congestionthresholds. A drop precedence is assigned to apacket to control its loss sensitivity relative to otherpackets when the packets are placed into the samequeue. Generally, the low value indicates the pack-et is less likely to be discarded when the queue iscongested. This traffic has a higher probability ofbeing forwarded. The high value indicates the pack-et is more likely to be discarded when the queue iscongested. This traffic has a lower probability of be-ing forwarded.

Initial Value

schedulingClass4Queues

Parameter name schedulingClass4Queues

Domain

Description This attribute specifies a logical scheduling classvalue in the range from 0 to 3 given to a packet thatuses the TrafficClass component instance. Thisvalue is used to select a queue when the packet istransmitted at an interface that supports fourqueues per connection. It may also be used to se-lect one of up to four link layer connections at inter-faces where per-packet selection of egress connec-tions is supported. A scheduling class is assignedto a packet to control its scheduling behavior relat-ive to other packets at the interface where the pack-ets are transmitted. Generally, a numerically highervalue indicates the packet is less likely to bedelayed. This traffic is considered more urgent andless delay tolerant. A numerically lower value indic-ates the packet is more likely to be delayed. Thistraffic is considered less urgent and more delay tol-erant. The actual scheduling behavior of packetsdepends on the scheduling mechanism at the inter-face. This value is also used to select a one of up tofour Layer 2 connections at the interface where thepacket is transmitted. Per- packet selection ofegress connections is supported only if these condi-tions are all true: i) for the Vr component, the valueof the associated mediaType attribute under the Ip-Port component is frameRelay, atmMpeLlcEncap,

576


or atmMpeVcEncap; for Router and Vrf, the mediaassociated with the interface is AtmMpe or IpoDlci.ii) more than one Layer 2 connection is configuredto the next hop IP router, and iii) each connection isconfigured with a different connection class value.Normally the packet is transmitted on the connec-tion whose connection class is equal to the schedul-ingClass4Queues value given to the packet. If thatconnection does not exist, then the connection hav-ing the next lower connection class is used. If thatconnection does not exist also, then the connectionhaving the next higher connection class is used.Locally generated IP multicast and IP broadcastpackets are not eligible for per-packet selection ofegress connections. Each of these packets iscopied and transmitted individually on each of theavailable connections to the next hop IP router. ForAtmMpe, the connection class is specified by the ip-Cos attribute of the AtmConnection subcomponent.For FrDte the connection class is specified by theipCos attribute of the StaticDlci and DynamicDlciDefsubcomponents. For IpDlciGroup and IpoDlci theconnection class is specified by the ipCos attributeof the FrConnection subcomponent. If each Layer 2connection is configured to provide different policingand scheduling characteristics, then the forwardingbehaviors of IP and MPLS packets are differenti-ated as they transit through the Layer 2 network. Ingeneral, the scheduling characteristics of the con-nections should be configured to be better for nu-merically greater connection class values. For ex-ample, if four AtmConnection components are as-sociated with AtmIf components configured for ATMservice classes UBR, nrtVBR, rtVBR, and CBR,then the ipCos attributes of the AtmConnectioncomponents should be either 0,1,2, and 3, respect-ively, or 0,1,3, and 2 respectively. The scheduling-Class4Queues attribute is set automatically to a de-fault value according to a function of the Traffic-Classcomponent instance value when the Traffic-Class component is created.

Locally generated routing controlpackets are treated with PHB CS6; other locallygenerated packets are treated with PHB DF. PerHop Behaviors CS6 and DF are configured toprovide the following values of scheduling class for8, 4, 3, 2 queues, drop precedence, and EXP forMPLS encapsulation: (5, 2, 2, 0, low, 6) and (0, 0,0, 0,, high, 0), respectively. This is equivalent to thedefault the configuration of the DifferentiatedSer-vicesDomain/custom component instance. If a Vpn-RouteForwarder component does not have a Differ-entiatedServicesDomain subcomponent, then theVpnRouteForwarder component uses the Differenti-atedServicesDomain configuration of the Router.

mode

Parameter name mode

Domain

Description This attribute specifies the protection mode to use.If set to value of unidirectional, the Laps componentof the near end (NE) can decide independently ofthe far end (FE) which channel, either working orprotection, is active for receive. For this value, thetransmit and receive may be on different channels.Therefore, one end may receive from the protectionline while the other end receives from the activeline. If set to bidirectional value, it instructs the Lapscomponent of the NE to decide jointly with the FEwhich channel, either working or protection, is to beactive for receiving. For this value, the transmit andreceive are on the same channel. Therefore bothends receive from the same line. If set to notApplic-able value, it instructs the Laps component not touse this attribute when no k-byte information is ex-changed. The notApplicable value must be usedwhen the yProtection protocol is set. Note that ifeither end of the Laps component is set to unidirec-tional, the Laps component operates in unidirection-al mode. In other words, bidirectional mode takeseffect if and only if both ends of the Laps compon-ents are in bidirectional mode.

Domain

Description This attribute specifies the protocol used to protectthe physical interfaces. The value standard indic-ates that 1+1 linear APS is used, as described inthe standards document GR-253 published by Tel-cordia and G.841 published by the ITU-T. The valueg841AnnexB indicates that optimized 1+1 bidirec-tional switching is used, as described in the stand-ard G.841 Annex B published by the ITU-T. Thisvalue is only supported on the 16pOC3SmIrAtm,16pOC3PosAtm and 4pMrPosAtm card type. Themode attribute must be set to bidirectional, the re-vertive attribute set to no, and the holdOffTime at-tribute set to 0 when the protocol attribute is set to

When this attribute value is set to no,the Laps component will not revert the receive act-ive line from protection back to working when aworking line request is cleared. When this attributevalue is set to yes, the Laps component will revertthe receive active line from protection back to work-ing when a working line request is cleared and afterthe provisioned value of waitToRestorePeriod attrib-ute has expired. When this attribute is set to notAp-plicable, it instructs the Laps component not to usethis attribute for the specified protocol. The notAp-plicable value must be used when the yProtectionprotocol is set because the concept of lineswitchover does not exist. Note that it is acceptablefor the near end and far end to be provisioned witha mix of revertive and nonrevertive switching; oneend can be revertive and the other nonrevertive.

sendLineAisDuringMigration

Parameter name sendLineAisDuringMigration

Domain

Description This attribute specifies whether Sonet/Sdh portslinked to a Laps component in an inter-card config-uration will send the Line Alarm Indication Signal(AIS-L) during the migration active stage of a Hit-less Software Migration or Hitless Software Patch-ing. The migration active stage for a card beginswhen the card is first loaded on the migration activeshelf and ends when the migration active shelf be-comes the active shelf. Sonet/Sdh ports are not inservice during the migration active stage of a soft-ware migration. Sending AIS-L during software mi-gration is used to inform the far end equipment thatthe Sonet/Sdh port is not available. If this attributeis set to no, the other end might try to use the Son-et/Sdh port that goes through a software migration.The recommended value for this attribute is yeswhen the far end equipment is another Nortel Net-works Multiservice Switch. If this attribute is set toyes, AIS-L is sent during software migration andthis may cause an extended traffic outage when theSonet/Sdh ports are connected to an equipmentthat delays clearing of Signal Degrade (SD) andSignal Fail (SF) conditions. Such delays are some-times implemented to reduce the number of rapidprotection switching oscillations. This attribute doesnot affect the behavior of Sonet/Sdh ports linked toa Laps component in an intra-card configuration orSonet/Sdh ports that are not linked to a Laps com-ponent.

signalDegradeRatio

Parameter name signalDegradeRatio

590


Domain

Description This attribute specifies the minimum bit error ratio(BER) for which a signal degradation failure is de-clared. Its value is the exponent of the BER, whichcorresponds to a BER range of 10e-5 through 10e-9. The switch initiation time for a signal degradationvaries depending on the observed BER (not theprovisioned signalDegradeRatio), as described inthe following table. BER - Switch Initiation Time(OC-3) 10e-5 - 1 second 10e-6 - 10 seconds 10e-7- 100 seconds 10e-8 - 16 minutes 40 seconds10e-9 - 2 hours 46 minutes 40 seconds The clear-ing threshold for a signal degradation is one-tenththe value of the signalDegradeRatio attribute. Forexample, if the provisioned signalDegradeRatio at-tribute is -5, the corresponding clearing threshold is10e-6. The clearing time varies depending on theclearing threshold (not the observed BER), and canbe determined from the above table. When this at-tribute is set to notApplicable, it instructs the Lapscomponent not to degrade Laps when BER is ob-served. The notApplicable value must be usedwhen the yProtection protocol is set.

The workingLine attributeand protectionLine attribute pairs must be valid.LAPS (Line Automatic Protection Switching) protec-tion can be configured between paired ports on thecard or between corresponding ports on adjacentcards. The following semantic checks exist for theworkingLine and protectionLine attributes: TheworkingLine and protectionLine attributes can linkports on two different LPs (Logical Processor): - theport number must match (that is, port zero on Lp/mmust link to port 0 on Lp/n, and so forth). - the Son-et or Sdh components specified by the link must nothave a Sts or Vc4 component. - each Lp must linkto exactly one card (that is, the spareCard attributeis not allowed to be set on either Lp). - each Lpmust link to the same type of card (that is, the shelfcard/n cardType attribute must be identical for bothcards). - the two cards must be in adjacent slots inthe shelf, with the lower- numbered slot being aneven number. - each Lp must link to the same Lo-gicalProcessorType component. - if the two lines ofthe protection pair are on different Lps, then theconnectionPoolCapacity attribute value of the LpEng Arc Ov components for the two adjacent Lpsmust be the same. The workingLine and protection-Line attributes can link to a pair of ports under thesame LP (Logical Processor) for the following

A smaller stratum value indicates a bettertopological distance to a time server. When thestratum reported by the remote time server exceedsthis value, alarm 70150015 is raised. A clear alarmis issued when the reported stratum is no longergreater than this value.

timeDifferenceLimit

Parameter name timeDifferenceLimit

Domain

Description This attribute specifies the allowed differencebetween the times reported by provisioned timeservers. The timeDifferenceLimit value is provi-sioned based on the sensitivity of time dependentapplications and the network topology in use. Anapplication more sensitive to time requires consist-ently close times reported by the time servers. Amore elaborate network topology may cause thetime servers to report a wider range of time differ-ences due to network delays than a simple network.An alarm is issued when the times reported by twotime servers differ by more than the specifiedamount. The value nolimit disables the check.

Every component has a CID. If a component has acid attribute, the component's CID is the provi-sioned value of that attribute; otherwise the com-ponent inherits the CID of its parent. The top- levelcomponent has a CID of 0. Every operator sessionalso has a CID, which is the CID provisioned for theoperator's user ID. An operator will see only thestream data for components having a matchingCID. Also, the operator will be allowed to issuecommands for only those components which have amatching CID. An operator CID of 0 is used toidentify the Network Manager (referred to as "Net-Man" in DPN). This CID matches the CID of anycomponent.

On CPSO, hot andwarm services are activated first followed by thecold services. Hence the activation time of cold ser-vices is potentially extended which will increase theservice outage, compared to when this attribute isset to cold. It is important to note that this attributedoes not make any service warm or hot; instead,CP based services are provided the ability to re-duce or eliminate call-setup outage due to a CPSOand to ensure stable calls are unaffected by aCPSO.

0051 alarm should be set once or repeated on aregular basis: on - specifies that the fan alarmshould be re-issued every eight hours until thealarm is cleared. Normally, the same alarm is neverre-issued in order to minimize the number of alarmsgenerated by a node. Nonetheless, selecting thisoption helps to compensate for the hardware limita-tion by providing a regular reminder (once per eighthour shift) that one or possibly more fans havefailed on this node. In addition, if the alarm condi-tion remains for more than 24 hours, the alarmseverity is increased. That is, the first three alarmsare issued with a severity of MAJOR, while all sub-sequent alarms have a severity of CRITICAL. off -specifies that the fan alarm be issued only onceupon failure.

Parameters:

autoConfirm

Parameter name autoConfirm

Domain

Description This attribute specifies whether the auto-confirmation functionality is turned on or off. Whenthe attribute is turned on, the operator need not is-sue a Confirm Prov command following an activa-tion. When the attribute is turned off, any activationshould be confirmed through the Confirm Prov com-mand. With this attribute turned on, if an activationinadvertently impacts management connectivity tothe shelf, then the shelf would remain isolated frommanagement perspective. Hence,it is strongly re-commended to have serial port access to the switchfor troubleshooting and recovery.

Initial value off

maxNumberJournalFiles

Parameter name maxNumberJournalFiles

Domain

Description This attribute specifies the maximum number ofjournal files that can be saved. A value of none spe-cifies that journaling is disabled, while any othervalue specifies that journaling is enabled. The ShelfcpEquipmentProtection attribute must be set to coldwhen the maxNumberJournalFiles attribute is set tonone. The value of the maxNumberJournalFiles at-tribute must be greater than the value of the ProvcurrentJournal operational attribute. If it is not, theresulting impact is that journal log file saving be-comes operationally disabled. A critical alarm withindex 7000 0037 is also raised against the Provcomponent. A Commit Prov command would needto be entered to re-enable journaling. The operatormay want to set the maxNumberJournalFiles attrib-ute to be less than the default value of 2000 in or-der to force a Commit Prov command to be enteredmore frequently. If a switch reset to the committedview occurs, the Restore Prov command may takeless time to complete in this case, since there arefewer journal log files to load and activate.

Domain

Description Em/string This component represents the localnode. An instance of the EM component class (withthe local node name as its instance string) is auto-matically created as the root of the component hier-archy; that is, all of the top level components are itssubcomponents. The local node name is provi-sioned as the nodeName attribute of the Mod-uleData component. An operator need not enter theEM component at the start of a component name;the local node is assumed by default. However, to
