ATM Commands on the Cisco IOS XR Software

atm address-registrationTo enable the router to engage in address registration and callback functions with the Interim LocalManagementInterface (ILMI), use the atm address-registration command in interface configuration mode. To disableILMI address registration functions, use the no form of this command.

atm address-registration

no atm address-registration

Syntax Description This command has no keywords or arguments.

Command Default If ILMI is configured on a PVC and its host ATM interface, then address registration and callback functionenabled on the router by default.

If ILMI is not configured on a PVC and its host ATM interface, then address registration and callbackfunctionality is disabled on the router and must be enabled with the atm address-registration command.

Command Modes Interface configuration (config-if)

Command History ModificationRelease

This command was introduced.Release 3.9.2

Usage Guidelines

The atm address-registration command is effective only when an ILMI PVC is created under the physicalATM interface.

ATM Commands on the Cisco IOS XR Softwareclass-vc

encapsulation (ATM)To configure the ATM adaptation layer (AAL) and encapsulation type for a virtual circuit (VC) class, ATMpermanent virtual circuit (PVC), or ATM permanent virtual path (PVP), use the encapsulation command inthe appropriate configuration mode. To remove an encapsulation type, use the no form of this command.

For point-to-point ATM PVCs and vc-classes:

encapsulation {aal5mux ipv4| aal5nlpid| aal5snap}

no encapsulation {aal5mux ipv4| aal5nlpid| aal5snap}

For ATM Layer 2 PVCs:

encapsulation {aal0| aal5}

no encapsulation {aal0| aal5}

Syntax Description Specifies IPv4 encapsulation for multiplex (MUX)-type VCs.

The aal5mux ipv4 keywords are available in ATM PVC configuration and ATMVC-class configuration modes only.

Note

aal5mux ipv4

Specifies the AAL and encapsulation type that allows ATM interfaces to interoperate withHigh-Speed Serial Interfaces (HSSIs), which are using an ATM data service unit (ADSU)and running ATM-Data Exchange Interface (DXI). Supported on ATM PVCs only.

The aal5nlpid keyword is available in ATMPVC configuration and ATMVC-classconfiguration modes only.

Note

aal5nlpid

Specifies the AAL encapsulation type that supports Inverse ARP. Logical LinkControl/Subnetwork Access Protocol (LLC/SNAP) precedes the protocol datagram.

The aal5snap keyword is available in ATMPVC configuration and ATMVC-classconfiguration modes only.

Note

aal5snap

Specifies the AAL encapsulation type that contains 48 bytes of data within an ATM cell.AAL0 cells are also referred to as raw cells. The payload consists of 48 bytes.

The aal0 keyword is available in the ATM Layer 2 transport PVC configurationmode only.

Note

aal0

Specifies the AAL encapsulation type that carries higher-layer datagrams while enhancingthe link layer with services available through ATM. AAL5 is defined in the ITU standardI.363.5, and is typically used to carry IP datagrams over ATM.

The aal5 keyword is available in the ATM Layer 2 transport PVC configurationmode only.

Note

aal5

Command Default For point-to-point PVCs, the default encapsulation type is aal5snap.

For Layer 2 PVCs, the default encapsulation type is aal5.


OL-26065-03 21

ATM Commands on the Cisco IOS XR Softwareencapsulation (ATM)


ATM VC-class configuration (config-vc-class-atm)

ATM layer 2 transport PVC configuration (config-atm-l2transport-pvc)



Usage Guidelines Use the aal5mux ipv4 encapsulation option to dedicate the specified PVC to a single protocol; use the aal5snapencapsulation option to multiplex two or more protocols over the same PVC. Whether you select aal5muxipv4 or aal5snap encapsulation depends on the type of network you are configuring, and the pricing offeredby that network. If the pricing of the network depends on the number of PVCs set up, we recommend aal5snapencapsulation. If pricing depends on the number of bytes transmitted, we recommend aal5mux ipv4encapsulation because it has less overhead than aal5snap and aal5mux ipv4 encapsulation.

If you configure VC-class parameters for a PVC after that PVC is configured, you must enter the shutdowncommand followed by the no shutdown command on the ATM subinterface that hosts the PVC. This actionrestarts the interface, causing the newly configured VC-class parameters to take effect on that interface.

Unless specifically configured otherwise, a PVC automatically inherits the encapsulation type of the VC-classthat is assigned to the main interface or subinterface that hosts the PVC. If no VC-class is assigned, then thePVC inherits the encapsulation type of the main interface or subinterface that hosts the PVC. If no encapsulationis configured of the main interface or subinterface, then the PVC inherits the default aal5snap encapsulation.

Use the encapsulation command in ATM PVC configuration mode to modify the inherited or defaultencapsulation assigned to a PVC. You can modify the encapsulation for each individual PVC to be differentfrom the encapsulation configured for the VC-class that is assigned to the ATMmain interface or subinterfacethat hosts the PVC.

If you do not use the encapsulation command to configure the encapsulation type for a new ATM PVC, thenthe PVC inherits the one of the following default configurations (listed in order of precedence from lowestto highest):

The encapsulation assigned to the VC-class that is assigned to the PVC itself.

The encapsulation assigned to the VC-class that is assigned to the ATM subinterface that hosts the PVC.

The encapsulation assigned to the VC-class that is assigned to the ATM main interface that hosts thePVC

The default aal5snap encapsulation

When configuring a PVC range or an individual PVC within a PVC range, the following encapsulation typesare supported:

encapsulation aal5mux ipv4

encapsulation aal5snap


22 OL-26065-03


For Layer 2 PVCs, the default encapsulation type is aal5, and the encapsulation type isnot inherited from the VC-class.

If the OAM AIS/RDI down count and up count is not configured for the VC-class, or if no VC-class isassigned to the main interface or subinterface that hosts the PVC, or to the PVC itself, then the PVCinherits the default OAM AIS/RDI down count and up count.

The default values for the OAM AIS/RDI down count and up count are used in the following situations:

If the oam ais-rdi command has not been entered

If the oam ais-rdi command is entered without the up-count or down-count argument

If the no oam ais-rdi command is entered

If the oam ais-rdi command is entered without the up-count or down-count argument, the command does notappear in the show running-config command output.

ATM Commands on the Cisco IOS XR Softwareoam-pvc manage

Usage Guidelines Keep the following in mind when configuring the OAM F5 loopback cell generation and CC managementfor an ATM PVC:

Unless specifically configured otherwise, a PVC automatically inherits the OAM F5 loopback cellmanagement configuration from the VC-class that is assigned to the main interface or subinterface thathosts the PVC.

If OAM F5 loopback cell generation is not enabled for the assigned VC-class, or if no VC-class isassigned to the PVC itself, or to main interface or subinterface that hosts the PVC, then OAMF5 loopbackcell generation is disabled on that PVC. To enable OAM F5 loopback cell generation on that PVC, youneed to use the oam-pvc manage command in ATM PVC configuration mode.

VC-classes support the configuration of the seconds argument only; the keep-vc-up, disable, andseg-aisrdi-failure keywords are available in ATM PVC configuration mode only and are configureddirectly on each individual PVC.

oam retryTo configure the number of F5 Operation, Administration, and Maintenance (OAM) loopback cells that needto be successfully transmitted by a down ATM permanent virtual circuit (PVC) before it is brought up, usethe oam retry command in ATM PVC configuration or ATM VC-class configuration mode. To return thePVC to the default behavior, use the no form of this command

oam retry [up-count [down-count [ retry-frequency ]]]

no oam retry [up-count [down-count [ retry-frequency ]]]

Syntax Description (Optional) Number of consecutive end-to-end F5 OAM loopback cell responses thatmust be received to change a connection state to up.

retry-count

(Optional) Number of consecutive unreceived end-to-end F5 OAM loopback cellsallowed on a PVC before its state changes to down.

down-count

(Optional) Frequency (in seconds) at which end-to-end F5 OAM loopback cells aretransmitted when a change in the up or down state is being verified. For example, ifa PVC is up and a loopback cell response is not received after the frequency (in seconds)is specified using the oam-pvc manage command, loopback cells are sent at the retryfrequency to verify whether the PVC is down.

retry-frequency

Command Default up-count: 3

down-count: 5

retry-frequency: 1 second


ATM VC-class configuration (config-vc-class-atm)



Usage Guidelines Keep the following in mind when configuring the OAM AIS/RDI down count and up count:

Unless specifically configured otherwise, a PVC automatically inherits the OAM AIS/RDI down countand up count of the VC-class that is assigned to the main interface or subinterface that hosts the PVC.


OL-26065-03 35

ATM Commands on the Cisco IOS XR Softwareoam retry

If no encapsulation is configured for the VC-class, or if no VC-class is assigned to the main interfaceor subinterface that hosts the PVC, or to the PVC itself, then the PVC inherits the default OAMAIS/RDIdown count and up count.

Keep the following in mind when configuring the F5 OAM loopback cell up count, down count, and retryfrequency:

Unless specifically configured otherwise, a PVC automatically inherits the F5 OAM loopback cell upcount, down count, and retry frequency of the VC-class that is assigned to the main interface orsubinterface that hosts the PVC.

If the F5 OAM loopback cell up count, down count, and retry frequency are not configured for theVC-class, or if no VC-class is assigned to the PVC itself, or to the main interface or subinterface thathosts the PVC, then the PVC inherits the default F5 OAM loopback cell up count, down count, and retryfrequency.

In other words, if the oam retry command is not explicitly configured on an individual PVC, then that PVCinherits the following default configuration (listed in order of precedence):

F5 OAM loopback cell up count, down count, and retry frequency configured for the VC-class that isassigned to the PVC itself

F5 OAM loopback cell up count, down count, and retry frequency configured for VC-class assigned tothe ATM subinterface that hosts the PVC

F5 OAM loopback cell up count, down count, and retry frequency configured for the VC-class assignedto the ATM main interface that hosts the PVC

For the defaults, it is assumed that OAM loopback cell generation is enabled on the PCV. To enable OAMF5 loopback cell generation, use the oam-pvc manage command.

ping atm interface atmTo verify connectivity between two ATM connection endpoints through a permanent virtual circuit (PVC)or VP-tunnel, use the ping atm interface atm command in EXEC mode.

ping atm interface atm interface-path-id [. subinterface] [vpi/vci] [end-loopback packets| seg-loopbackpackets] [timeout seconds]

Syntax Description Physical interface or virtual interface followed by the optional subinterface pathID. Naming notation is interface-path-id.subinterface. The period in front of thesubinterface value is required as part of the notation.

For more information about the syntax for the router, use the question mark (?)online help function.

interface-path-id[.subinterface]

(Optional) ATM virtual path identifier (VPI) and virtual channel identifier (VCI)numbers. The absence of the slash (/) and a vpi value defaults the vpi value to 0.

A VPI of 0 is not applicable to VP-tunnels or Layer 2PVPs.

Note

vpi/vci

(Optional) Sends a specified number of end-to-end OAM loopback packets overthe connection. Replace packets with the number of end-to-end OAM loopbackpackets you want to send over the ATM interface.

end-loopback packets

(Optional) Sends a specified number of segmented OAM loopback packets overthe connection. Replace packets with the number of OAM loopback packets youwant to send over the ATM interface.

seg-loopback packets

Predetermined time during which the destination can send an OAM loopbackresponse cell back to the source. Replace seconds with number of seconds to waitfor an OAM loopback response before the ping times out. The default value of thetimeout is 2 seconds on Cisco routers.

ATM Commands on the Cisco IOS XR Softwareping atm interface atm

The ping atm interface atm command sends an OAM packet to verify ATM PVC connectivity. The statusof the PVC is displayed when a response to the OAM packet is received. This is a common method for testingthe accessibility of the devices.

The ping atm interface atm command is used to determine the following:

Whether a remote host is active or inactive.

The round-trip delay in communicating with the host.

Packet loss.

For the interface-path-id argument, use the following guidelines:

If specifying a physical interface, the naming notation is rack/slot/module/port. The slash between valuesis required as part of the notation. An explanation of each component of the naming notation is as follows:

rack: Chassis number of the rack.

slot: Physical slot number of the line card.

module: Module number. A physical layer interface module (PLIM) is always 0.

port: Physical port number of the interface.

If specifying a virtual interface, the number range varies, depending on interface type.

Include the end-loopback packets keyword argument with the ping atm interface atm command to verifyend-to-end PVC integrity.

Include the seg-loopback packets keyword argument with the ping atm interface atm command to verifyPVC integrity to the immediate neighboring ATM device.

The ping command is not available for Layer 2 ACs.Note

ATM Commands on the Cisco IOS XR Softwareping atm interface atm

pvc (ATM)To create an ATM permanent virtual circuit (PVC) with Interim Local Management Interface (ILMI)encapsulation and enter ATMvirtual circuit configurationmode, use the pvc command in interface configurationmode or subinterface configuration mode. To remove an ATM PVC from an interface, use the no form ofthis command.

In interface configuration mode for a point-to-point ATM main interface:

pvc vpi/vci ilmi

no pvc vpi/vci ilmi

In interface configuration mode for an ATM subinterface:

pvc vpi/vci

no pvc vpi/vci

Syntax Description ATM network virtual path identifier (VPI) for this PVC.

If support for the 12-bits VPI Network-Node Interface (NNI) cell format is enabled on the ATMmain interface that hosts this PVC, then the range is from 0 through 4095.

If support for the 12-bits VPI NNI cell format is not enabled on the host ATM main interface,then the range is from 0 through 255.

To enable support for the 12-bits VPI NNI cell format on the main ATM interface hostingthe specified PVC, use the atm maxvpi-bits 12 command.

Note

vpi/

ATM network virtual channel identifier (VCI) for this PVC. Range is from 1 through 65535.

The VCI is a 16-bit field in the header of the ATM cell. The VCI value is unique only on a singlelink, not throughout the ATM network, because it has local significance only.

Typically, lower values from 1 through 18 are reserved for specific traffic (for example,F4 OAM, ILMI, and so on), and should not be used.

Note

The vpi and vci arguments cannot both be set to 0; if one is 0, the other cannot be0.

Note

vci

Sets up communication with the Interim LocalManagement Interface (ILMI). The associated VPIis 0, and VCI the associated VCI is any VCI.

VCI 16 is typically used forILMI.

Note

The ilmi keyword is available for point-to-point ATM interfacesonly.

Note

ilmi

Command Default No PVC is defined.

ATM Commands on the Cisco IOS XR Softwarepvc (ATM)

Subinterface configuration (config-subif)



Usage Guidelines The pvc command creates a PVC and attaches it to the specified VPI and VCI. Both the vpi and vci argumentscannot be simultaneously specified as 0; if one is 0, the other cannot be 0.

Cisco IOS XR software dynamically creates rate queues as necessary to satisfy the requests of the PVCcommands.

When you issue the pvc command in interface or subinterface configuration mode for a point-to-point ATMmain interface, the CLI prompt changes to config-atm-vc, indicating that you have entered the ATM virtualcircuit configuration submode.

Although the CLI prompt looks the same for the ATM virtual circuit configuration submode under theATM main interface and the ATM subinterface in point-to-point configurations, the commands that areavailable under each interface type vary.

Note

When you issue the pvc command in subinterface configuration mode for an ATM AC, the CLI promptchanges to config-atm-l2transport-pvc, indicating that you have entered the ATM layer 2 transport PVCconfiguration submode.

For the 4-Port OC-3 and 4-Port OC-12 line cards, the VCI range is 19 through 65535.Note
