1.1 Overview

The following describes the overview of the Switch Blade.

PRIMERGY BX600 Blade Server

A high performance Giga-bit Ethernet Switch Blade used for network connection is installed in

PRIMERGY BX600. This Switch Blade, which is equipped with 10 full-duplex Giga-bit ports used for

server blade connection, enables high-speed access to server resources. The Switch Blade is also

equipped with 3 full-duplex Giga-bit ports that are used for uplink to network backbone or connection to

other server farms.

PRIMERGY BX600 Switch Blade

This Switch Blade uses high-speed switching fabric. This design allows for simultaneous transport with

low latency of multiple packets for all ports. It also adopts store-and-forward switching to ensure

maximum data integrity. In this mode, the entire packet must be received into a port buffer and checked

for validity before being forwarded. This prevents errors from spreading throughout the network.

A management agent is installed in the Switch Blade, and can be accessed using the console redirection

function of the Management Blade.

The Switch Blade can also be managed using Web browser, SNMP/RMON software, or Telnet.

1.2 About Hardware

The following explains the network environment of the Switch Blade.

1.2.1 Ethernet Port

The RJ-45 uplink ports support IEEE 802.3x auto-negotiation of speed, duplex mode, and flow control.

Each port operates with data transmission rates of 10Mbps/100Mbps/1000Mbps, full-duplex/half-

duplex mode, and can avoid buffer overflow by controlling data stream. These external ports can be

connected to IEEE802.3ab 1000BASE-T compliant devices within a range of 100m using a category 5e

twisted pair cable. Since these ports have an automatic MDI/MDI-X switching function, a straight cable

can be used for every connection (Auto-negotiation must be enabled when using an MDI/MDI-X

switching function).

When using auto-negotiation function for this switch, data transmission rate, transmission mode, and

flow control will be set automatically also for the connected device if this function is supported by the

device. If the function is not supported, every connection must be set manually.

1.3 Network Management

An embedded network management agent is installed in the Switch Blade. For this

agent, various management options, such as SNMP, RMON, and Web-based

interfaces, are available. A PC can be connected to the Switch Blade in order to

configure and monitor the Switch Blade.

The network management agent provides a wide range of high performance expansion functions as

follows.

• The multicast filtering function supports real-time network applications.

• Port-based and tagged VLAN provide traffic security and efficient use of the network bandwidth.

• The QoS priority queueing ensures the minimum delay for moving real-time multi-media data across

the network.

• The flow control function protects packets from losses that may be caused by a bottleneck due to port

saturation.

• The broadcast storm suppression function protects the network from broadcast traffic storms. This section briefly explains some management functions.

IEEE 802.1D compliant bridge

The Switch Blade supports IEEE 802.1D transparent bridging. It refers to learned addresses data in an

address table, and according to the information, performs filtering or forwarding of traffic to facilitate

data switching. Up to 32,000 addresses can be registered in the address table.

Store-and-Forward switching

The Switch Blade copies each frame to the memory, and then transmits the frame to another port. This

makes every frame the standard Ethernet size. In addition, data integrity checks are performed reliably

using a cyclical redundancy check.

This function prevents an invalid frame from entering the network, and avoids wasted bandwidth.

To avoid frame losses in a port where access is congested, This buffer can keep packets in a queue and

hold data transmission, when network access is congested.

Spanning tree protocol

The Switch Blade supports IEEE 802.1D spanning tree protocol. This protocol improves fault tolerance,

enabling configuration of redundant connections consisting of two or more routes between a pair of

LAN segments. If there are multiple physical paths between segments, this protocol selects one path and

disables the other paths. Therefore, there will be only one path between two stations on the network.

This prevents the creation of network loops. However, if the selected path fails for some reason, an

alternative path is activated so that the connection is maintained.

15

1


Virtual LAN (VLAN)

Using the Switch Blade, up to 32 VLANs can be configured. Virtual LAN is a group of network nodes

sharing the same collision domain regardless of physical node locations and connection points. The

Switch Blade supports IEEE 802.1Q compliant tagged VLAN. A port can be manually assigned to a

specific set of VLANs. As a result, the switch can restrict the traffic transmitted to a VLAN group to

which a user has been assigned. The following will be possible by segmenting the network into VLANs.

• Avoiding broadcast storms that cause significant performance deterioration.

• Making network management easy when changing or moving nodes, by setting remotely VLAN

membership for any port, not by manually changing node IP addresses.

• Providing data security by restricting all traffic to the originating VLAN (except when a connection

between different VLANs is established using a router or layer 3 switch).

Port mirroring

The Switch Blade can copy traffic from any port to the monitor port. In addition, the traffic can be

analyzed and connection integrity can be checked, by connecting a protocol analyzer or RMON probe to

the monitor port.

Port trunking

An aggregate connection can be configured by combining external ports 11 and 12. The second port

increases the whole connection throughput dramatically, and if an error occurs at one port in the trunk,

redundancy is provided by the other port taking over the load. The Switch Blade supports one trunk that

includes two uplink ports.

Broadcast suppression

This controls broadcast traffic so that it does not damage network traffic. When this function is enabled

at a port, the level of broadcast traffic passing the port is restricted. If the broadcast traffic exceeds the

threshold level set in advance, the traffic will be reduced to under the threshold level.

Flow control

This lightens the traffic when accesses are congested, and avoids packet loss caused by port buffer

overflow. The Switch Blade supports IEEE 802.3x compliant flow control. Flow control of all ports is

disabled by default.

Traffic priority

Quality of Service (QoS) is realized by prioritizing each packet according to the required service level,

using four priority queues that adopt weighted round robin queuing. For prioritizing the receiving traffic,

IEEE 802.1p tag and 802.1Q tag are used according to the input from end-station application. Using

these functions, it is possible to prioritize the delay-sensitive data and the best-effort data separately.

Multicast switching

Specific multicast traffic can be assigned to its own VLAN to ensure that it does not interfere with

normal network traffic and to guarantee real-time delivery by setting the required priority level for the

designated VLAN. The Switch Blade manages multicast group registration, using IGMP snooping and

IGMP.

1.7 Initial Setup

Before using the Switch Blade, the following initial setup must be carried out.

1 Access the command line interface (CLI) using the console redirection function

of Management Blade.

For the access procedure, refer to " Console Connection" (pg.100) in "4.1.1 Accessing the

CLI".

2 Change the default password using CLI.

For details, refer to "4.1.2 Setting a Password" (pg.102). To ensure security, make sure to

change the password.

When using Web interface or command line interface that uses Telnet as a management tool, it is

required to set an IP address for Switch Blade management.

3 Set an IP address using CLI.

There is no default IP address. For details, refer to "4.1.3 Setting an IP Address" (pg.103).

Other setups

Even if the Switch Blade setting is still "default", it works without any problems. However, to use all the

functions of the Switch Blade, the setup needs to be changed. For details, refer to "Chapter 3

Configuring the Switch" (pg.29).

When changing the settings, be sure to refer to "3.6.2 Saving or Restoring Configuration Settings"

(pg.46) and save the setting data. When replacing the Switch Blade during maintenance, the

settings return to the initial settings (the settings at purchase). Therefore, reset the settings using

the saved setting data.

2.1 Configuring a Network

The Switch Blade connects the server blades installed in the system to shared switch

fabric, and also provides 3 external ports for uplinking to external devices compliant

with IEEE 802.3ab. The external ports of the Switch Blade are often connected to

other ports in the network backbone. They can also be connected directly to Gigabit

Ethernet network cards of PC or server.

• Setup a spanning tree protocol before connecting cables, so as not to cause network loops.

For details, refer to "3.8 Spanning Tree Protocol Configuration" (pg.55).

2.2 1000BASE-T Device Connection

The Switch Blade data ports support the following functions.

• Data transmission rates of 10Mbps/100Mbps/1000Mbps

• Operation in full-duplex/half-duplex mode

• Auto-negotiation function of transmission rate, duplex mode, and flow control

Each external data port of the Switch Blade can be connected to any server or

workstation, and the ports can uplink to network devices such as other switches and

routers. According to the 1000BASE-T standard, 4 pairs of category 5e twisted pair

cables are used, for maximum 100m connection.

First, check whether IEEE 802.3ab 1000BASE-T compliant cables are connected when using

1000Mbps operation. For details, refer to "2.3 1000BASE-T Cable Requirements" (pg.26).

1 Prepare devices to be used in the network.

Check whether 1000BASE-T network interface cards are installed in servers and workstations

when using 1000Mbps operation. In the other network devices, IEEE 802.3ab 1000BASE-T

compliant RJ-45 ports must be installed.

2 Prepare shielded or non-shielded twisted pair cables (straight cables or cross

cables) with RJ-45 plugs at both ends.

For 1000Mbps Gigabit Ethernet connection, 100-ohm category 5e cables are used.

3 Connect one end of the cable to other device's RJ-45 port, and the other end to

an available port of the Switch Blade.

To connect the RJ-45 plug, click it into place so that the tab of the plug is fixed correctly.

For 1000Mbps operation, all wires of 4 pairs of cables must be connected. When the auto-negotiation function is enabled, the automatic MDI/MDI-X function is supported at the

1000BASE-T ports. As a result, regardless of the data transmission rate (10/100/1000Mbps) or type of

cable (straight or cross), the Switch Blade can be connected to servers, workstations, or other network

devices. Do not use a twisted pair cable longer than 100m (328 feet). (The auto-negotiation function must be enabled to support the automatic MDI/MDI-X function).

• Do not try to insert a modular jack connector into RJ-45 port. Doing so may cause damage to

the switch. Be sure to use twisted pair cables with RJ-45 connector compliant with FCC

standards.

2.3 1000BASE-T Cable Requirements

Category 5 UTP cables for 100BASE-TX may be used for 1000BASE-T if all wires of

4 pairs are connected. However, when newly wiring cables, use category 5e

(enhanced category 5) cables. The category 5e cable standards include the test parameters that were merely

recommended values in category 5. Therefore, before using existing category 5

cables for 1000BASE-T, it is required to perform a brief cable wiring test so that the

cables are verified to be compatible to IEEE 802.3ab standards.

2.3.1 Test for Existing Category 5 Cable

Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk (NEXT), and Far-End

Crosstalk (FEXT). This cable testing information is specified in the ANSI/TIA/EIA-TSB-67 standard.

Additionally, cables must also pass test parameters for Return Loss and Equal-Level Far-End Crosstalk

(ELFEXT). These tests are specified in the ANSI/TIA/EIA-TSB-95 Bulletin, "The Additional

Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling".

2.4 1000BASE-T Pin Assignments

1000BASE-T ports support automatic MDI/MDI-X switching operation, so you can

use straight cables for all network connections to PCs or servers, or to other switches

(Auto-negotiation must be enabled when using an MDI/MDI-X switching function).

The table below shows the 1000BASE-T MDI and MDI-X port pin assignments. These ports require

that all four pairs of wires be connected. Note that for 1000BASE-T operation, all four pairs of wires are

used for both transmit and receive ports.

Use 100-ohm Category 5e unshielded twisted-pair (UTP) cable for 1000BASE-T connections. Also be

sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).

3.1 About Web UI

In the Switch Blade, an embedded HTTP Web server is installed. Using a Web

browser, you can set up the switch and view statistics on the Web browser to monitor

network activity. The Web server can be accessed by any computer on the network

using a standard Web browser (Internet Explorer 5.0 or above, or Netscape

Navigator 6.1 or above).

The Switch Blade can be managed by the command line interface (CLI) using the console redirection

function of Management Blade or Telnet. For CLI usage details, refer to "Chapter 4 Command

Reference" (pg.99).

Before accessing the Switch Blade from a Web browser, be sure you have performed the following

settings:

1 Set a valid IP address, subnet mask, and default gateway in the Switch Blade,

using the console redirection function of Management Blade.

"1.7 Initial Setup" (pg.21)

If the path between the management station and this switch does not pass through any device that

uses the Spanning Tree Algorithm, then you can set the switch port attached to the management

station to "Fast Forwarding" to improve the switch's response time to management commands issued

through the Web UI (" bridge-group portfast" (pg.171)).

Web UI may not be initialized and may not be accessed, if opening the Switch Blade CLI using the

console redirection function of Management Blade in the time between turning on the main power

switch of the chassis and completing Switch Blade startup. In this case, end the console redirection

and access the Web UI again.

3.2.3 Setting the IP Address

The switch does not have a default IP address. The user needs to manually set a new IP address as

necessary. You may also need to establish a default gateway between this Switch Blade and management

stations that exist on another network segment.

The switch does not have a default IP address.

IP address is assigned to only one VLAN (Management VLAN).

You can manually configure a specific IP address, or direct the device to obtain an IP address from a

BOOTP or DHCP server. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by

periods. Anything outside this format will not be accepted by the CLI program.

Command attributes

The following describes the commands and their attributes for setting the IP address.

Command Attribute

Management VLAN This is the only VLAN through which you can gain management access to

the switch.

By default, all ports on the switch are members of VLAN 1, so a

management station can be connected to any port on the switch. However, if

other VLANs are configured and you change the Management VLAN, you

may loose management access to the switch. In this case, you should

reconnect the management station to a port that is a member of the

Management VLAN.

IP Address Mode Specifies whether IP functionality is enabled via manual configuration

(Static), Dynamic Host Configuration Protocol (DHCP), or Boot Protocol

(BOOTP).

If DHCP or BOOTP is enabled, IP will not function until a reply has been

received from the server. Requests for an IP address will be broadcast

periodically by the switch. (Using DHCP or BOOTP, values of the IP

address, default gateway, and subnet mask can be set.)

IP Address IP address of the VLAN interface that is allowed management access.

Valid IP addresses consist of four decimal numbers, 0 to 255, separated by

periods.

Subnet Mask This mask identifies the host address bits used for routing to specific

subnets.

Gateway IP Address IP address of the gateway router between the Switch Blade and management

stations that exist on other network segments.

MAC Address MAC address of the Switch Blade

Updating DCHP

DHCP may lease addresses to clients indefinitely or for a specific period of time. If the address expires

or the switch is moved to another network segment, you will loose management access to the switch. In

this case, you can reboot the switch or submit a client request to restart DHCP service.

Web UI

If the address assigned by DHCP does not work, you cannot update the IP setting from the Web UI.

3.3 Configuring SNMP

An onboard agent is installed in the switch.

The onboard agent continuously monitors the status of switch hardware, as well as

the traffic passing through its ports, based on the Simple Network Management

Protocol (SNMP).

Access rights to the onboard agent are controlled by community strings. To communicate with the

switch, the management station must first submit a valid community string for authentication. The

options for configuring community strings and related trap functions are described in the following

sections.

3.3.1 Setting Community Access Strings

You may configure up to five community strings authorized for management access.

For security reasons, it is recommended to remove the default community string.

Command attributes

The following describes the commands and their attributes for setting the community access strings.

Web UI

1 Click [SNMP].

2 Enter a community string in the "Community String" box and select the access

rights from the "Access Mode" drop-down list.

3 Click [Add].

Command Attribute

Community String A community string acts like a password and permits access to the SNMP

protocol. (Max. 32 characters)

Access Mode Read-Only: Specifies read-only access rights. Authorized management

stations are only able to refer to MIB objects.

Read/Write: Specifies read-write access rights. Authorized management

stations are able to both refer to and modify MIB objects.

CLI

The following example adds the string "batman" as a community string, and provides read/write access

rights.

3.3.2 Specifying Trap Managers

You can specify up to five management stations that will receive authentication failure messages and

other trap messages from the switch.

Command Usage

• You can enable or disable authentication messages via the Web UI.

• You can enable or disable authentication messages, link-up-down messages, or all notification types

via the CLI.

Web UI

1 Click [SNMP].

2 Fill in the "Trap Manager IP address" box and "Trap Manager Community

3.4 Setting the Logon Password

Guest account merely has read-only rights for most parameters. Administrator

account has the rights to overwrite parameters for setting the Switch Blade.

Therefore, it is necessary to assign a password to the administrator account as soon

as possible, and store the password to a safe place (if the password was lost for

some reason, you can reload the runtime code and restore the default password).

The default guest account is "guest", and its password is also "guest". The default administrator

account is "admin", and its password is also "admin".

User name can be assigned only when setting by CLI.

Web UI

1 Click [Security].

2 Enter the current password in "Old Password" and a new password in "New

Password".

3 To confirm the new password, enter the new password of Step 2 again in

"Confirm Password".

4 Click [Apply].

CLI

Assign access level 0 (read-only access rights) or access level 15 (read-write access rights) to the user

name, and then specify a password.

3.5 Using Jumbo Frames

This switch increases throughput for transmitting large sequential data, by supporting

up to 9000bytes jumbo frame.

When using a jumbo frame, you can significantly decrease overhead per packet

needed for capsulating data with the protocol, compared with using a standard

Ethernet frame that can transmit 1518bytes or less.

In order to use jumbo frames, the end-nodes (computers/servers) of both source and destination must

support this function. In addition, when the network connection is full-duplex mode, all the switches

between the two end-nodes must be able to handle the extended frame size data. Moreover, when the

network is half-duplex mode, all devices within the collision domain must support jumbo frame.

When jumbo frame is enabled, the maximum threshold value for controlling broadcast storm is limited

to 64 packets/sec. "3.13.3 Setting Broadcast Storm Thresholds" (pg.92)

Web UI

1 Click [Jumbo Frame].

2 Select "Enabled" from the drop down box, and then click [Apply].

3.6 Managing Firmware/Setting Data

You can upload/download firmware and setting data to/from a TFTP server.

By saving runtime code to a file on a TFTP server, that file can later be downloaded

to the switch to restore. You can also set the switch to use new firmware without

overwriting the firmware or setting data on the previous version by saving them in the

memory area of the Switch Blade.

Command attributes

• The destination file name should not contain slashes (/) or backslashes (\), and the leading character

of the file name should not be a period (.). The file name must consist of from 1 to 31 characters.

• Up to 2 runtime files can be saved.

3.6.1 Downloading System Software from a Server

3.7 Address Table Settings

Switches store the addresses for all known devices. This information is used to route

traffic directly between the inbound and outbound ports. All the addresses learned by

monitoring traffic are stored in the dynamic address table.

You can also manually configure static addresses that are bound to a specific port.

3.7.1 Displaying the Address Table

The Dynamic Address Table contains the MAC addresses learned by monitoring the source address for

traffic entering the switch. When the destination address for inbound traffic is found in the database, the

packets intended for that address are forwarded directly to the associated port. Otherwise, the traffic is

broadcast to all ports.

Command Usage

• You can display entries in the dynamic address table by selecting an interface (either port or trunk),

MAC address, or VLAN.

• You can sort the information displayed based on interface (port or trunk), MAC address, or VLAN.

Web UI

1 Click [Address Table], and then [Dynamic Addresses]

3.8 Spanning Tree Protocol Configuration

The Spanning Tree Algorithm (STA) is used to detect and disable network loops, and

to provide backup links between switches, bridges, or routers. This allows the switch

to interact with other bridging devices (that is, an STA-compliant switch, bridge, or

router) in the network. As a result, only one route exists between any two stations on

the network, and backup links automatically take over when a primary link goes

down.

3.8.1 Configuring Global Settings

Global settings apply to the entire switch.

Command attributes

The following global attributes can be changed:

Command Attribute

Spanning Tree State Enables/disables this switch to participate in a STA-compliant network.

Priority Bridge priority is used in selecting the root device, root port, and designated

port. The device with the highest priority (i.e. the lowest priority value)

becomes the STA root device.

However, if all devices have the same priority, the device with the smallest

MAC address will then become the root device.

• Default: 32768

• Range: 0–65535

Hello Time Interval (in seconds) at which the root device transmits a configuration

message.

• Default: 2

• Minimum: 1

• Maximum: The lower of 10 or [(Max. Message Age / 2) -1]

Maximum Age The maximum time (in seconds) a device can wait without receiving a

configuration message before attempting to reconfigure.

All device ports (except for designated ports) should receive configuration

messages at regular intervals (provided in the last configuration message).

Any port that ages out STA information becomes the designated port for the

attached LAN. If it is a root port, a new root port is selected from among the

device ports attached to the network. (References to "ports" in this section

mean "interfaces", which include both ports and trunks).

• Default: 20

• Minimum: The higher of 6 or [2 × (Hello Time + 1)].

• Maximum: The lower of 40 or [2 × (Forward Delay - 1)]

Web UI

1 Click [STA], and then [STA Information].

Forward Delay The maximum time (in seconds) the root device will wait before changing

states (i.e., listening to learning to forwarding).

This delay is required because every device must receive information about

topology changes before it starts to forward frames. In addition, each port

needs time to receive conflicting information that would make it return to a

blocking state. Otherwise, temporary data loops might result.

• Default: 15

• Minimum: The higher of 4 or [(Max. Message Age / 2) + 1]

• Maximum: 30

Command Attribute

Bridge ID The priority and MAC address of this device.

Designated Root The priority and MAC address of the device in the Spanning Tree that this

switch has accepted as the root device.

Root Port The number of the port that has the lowest path cost to the root on this

Switch Blade.

This Switch Blade communicates with the root device through this port. If

there is no root port, then this Switch Blade has been accepted as the root

device of the Spanning Tree network.

Root Path Cost The path cost from the root port on this switch to the root device.

3.8.2 Configuring Interface Settings

You can configure STP attributes for specific interfaces, including port priority, path cost, and fast

forwarding. You may use a different priority or path cost for ports of same media type to indicate the

preferred path.

Command attributes

The following interface attributes can be changed:

Command Attribute

Priority Defines the priority used for this port in the Spanning Tree Protocol. If the

path cost for all ports on a switch is the same, the port with the highest

priority (i.e. lowest value) will be configured as an active link in the

Spanning Tree. This makes a port with higher priority less likely to be

blocked if the Spanning Tree Protocol detects network loops. Where more

than one port is assigned the highest priority, the port with the lowest port

number will be enabled.

• Default: 128

• Range: 0–255

Path Cost This parameter is used by the STP to determine the best path between

devices. Therefore, lower values should be assigned to ports attached to

faster media, and higher values assigned to ports with slower media. (Path

cost takes precedence over port priority.)

• Possible setting range: 1 - 65535

• Recommended setting range:

• Ethernet: 50–600

• Fast Ethernet: 10–60

• Giga-bit Ethernet: 3–10

• Default:

• Ethernet: half duplex: 100; full duplex: 95; trunk: 90

• Fast Ethernet: half duplex: 19; full duplex: 18; trunk: 15

• Giga-bit Ethernet: full duplex: 4; trunk: 3

Fast Forwarding Since end-nodes cannot cause forwarding loops, they can pass directly

through to the Forwarding state. Fast Forwarding can achieve quicker

convergence for end-node workstations and servers, and also overcome other

STA related timeout problems. (Remember that Fast Forwarding should only

be enabled for ports connected to an end-node device.) Set "Enable" for ports

1 - 10.

• Default:

• Ports 1 -10: Enable (Fixed parameter)

• Ports 11 -13: Disable

forward packets.

• Listening: The port changes from blocking because the topology was changed.

It starts sending configuration messages, but it does not start forwarding

packets yet.

• Learning: The port did not receive conflicting information, and sent

configuration messages at the interval specified by the Forward Delay

parameter. The port address table is cleared and the port starts learning

addresses.

• Forwarding: The port forwards packets and continues learning addresses.

• Broken: The port is broken or the link has not been established.

Forward Transitions Shows the number of times that the port changed from the "Learning" state to the

"Forwarding" state.

Designated Cost The cost for sending packets from this port to the root bridge in the current

Spanning Tree settings. The slower the media is, the higher the cost.

Designated Bridge Shows the MAC address and priority of the device to which this port must

communicate in order to reach the root bridge in the Spanning Tree.

Designated Port Shows the port number and priority of the specified bridge device which this

switch must pass through in order to reach the root bridge in the Spanning Tree.

3.10Class of Service Configuration

Class of Service (CoS) allows you to specify which data packets have priority when

traffic is buffered in the switch due to access congestion. This switch supports CoS

with four priority queues for each port. Data packets in a port's high-priority queue will

be transmitted before those in the lower-priority queues.

You can set the default priority for each interface, and configure the mapping of frame

priority tags to the switch's priority queues.

3.10.1 Setting the Default Priority for Interfaces

You can specify the default priority for each interface on the switch.

All untagged packets entering the switch are tagged with the specified default port priority, and then

sorted into the appropriate priority queue at the output port.

Command Usage

• This switch provides four priority queues for each port.

• These priority queues use a weighted round robin algorithm to prevent head-of-queue blockage.

• The default priority applies if the incoming frame is an untagged frame received from a VLAN trunk

or a static-access port. This priority does not apply to IEEE 802.1Q VLAN tagged frames. If the

incoming frame is an IEEE 802.1Q VLAN tagged frame, the IEEE 802.1p user priority bits will be

used.

• If the output port is an untagged member of the associated VLAN, these frames are stripped of all

VLAN tags before transmission.

Command attributes

3.11VLAN Configuration

In conventional networks with routers, broadcast traffic is split up into separate

domains. However, in principle switches cannot divide a broadcast domain. This can

lead to broadcast storms in large networks that handle traffic such as IPX or NetBeui.

By using IEEE 802.1Q-compliant VLANs with this switch, you can organize any group of network

nodes into separate broadcast domains, thus confining broadcast traffic to the originating group.

This also provides a more secure and simpler network environment with lower broadcast traffic.

An IEEE 802.1Q VLAN is a group of ports that can be located anywhere in the network, but

communicate as though they belong to the same physical segment.

VLANs help to simplify network management by allowing you to move devices to a new VLAN

without having to change any physical connections. VLANs can be easily organized to reflect the

requirements of departmental groups (such as Marketing or R&D), usage groups (such as e-mail), or

multicast groups (used for multimedia applications such as videoconferencing).

VLANs provide greater network efficiency by reducing broadcast traffic, and allow you to make

network changes without having to update IP addresses or IP subnets. VLANs provide a high level of

network security since traffic must pass through a configured Layer 3 link to reach a different VLAN.

This switch supports the following VLAN features:

• Up to 32 VLANs based on the IEEE 802.1Q standard

• Port overlapping, allowing a port to participate in multiple VLANs

• End stations can belong to multiple VLANs

• Passing traffic between VLAN-aware and VLAN-unaware devices

• Priority tagging

When using the VLAN function of the Switch Blade to split the network into 2 or more, a server blade

cannot be installed to server blade slot 5 in the chassis. The maximum number of server blades that

can be installed is 9.

The Spanning Tree function of this switch works regardless of the VLAN configuration. Therefore, if

network loops are configured, all ports except for one port are disabled, even if they belong to

different VLANs, so the VLANs to which the disabled ports belong may not be able to communicate.

When using VLAN and configuring network loops, disable Spanning Tree.

69

7


Assigning Ports to VLANs

Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) in which it

will participate. By default, all ports are assigned to VLAN 1 as untagged ports.

Add a port as a tagged port (that is, a port connected to a VLAN-aware device) if you want it to carry

traffic for one or more VLANs, and if the device at the other end of the link also supports VLANs. Then

assign the port at the other end of the link to the same VLAN(s). However, if you want a port on this

switch to participate in one or more VLANs, but the device at the other end of the link does not support

VLANs, then you must add this port as an untagged port (that is, a port connected to a VLAN-unaware

device).

VLAN Classification

When the switch receives a frame, it classifies the frame in one of the following two ways.

• If the frame is untagged, the switch assigns VLAN ID to the frame based on the PVID of the

receiving port.

• If the frame is tagged, the switch uses the tagged VLAN ID to identify the port broadcast domain of

the frame.

Port Overlapping

Port overlapping can be used to allow access to commonly shared network resources among different

VLAN groups, such as file servers or printers. If you implement VLANs which do not overlap, and need

to communicate, you can connect them by using a Layer-3 router or switch.

Port-based VLANs

Port-based (or static) VLANs are manually assigned to specific ports. The switch's forwarding decision

is based on the destination MAC address and its associated port. Therefore, to make valid forwarding or

flooding decisions, the switch must learn the relationship of the MAC address to its related port (and

thus to the VLAN) at run-time.

Forwarding Tagged/Untagged Frames

If you want to create a small port-based VLAN for devices attached directly to a single switch, you can

assign ports to the same untagged VLAN. However, to participate in a VLAN group that crosses several

switches, you need to create a VLAN for that group and enable tagging on all ports.

Multiple tagged or untagged VLANs can be assigned to ports. Therefore, each port on the switch is

capable of passing tagged or untagged frames. To forward a frame from the switch (i.e. VLAN-aware

device) to a VLAN-unaware device, the switch first decides where to forward the frame, and then inserts

the VLAN tag which indicates the default VID of this port.

3.11.6 Configuring VLAN Behavior for Interfaces

You can configure VLAN behavior for specific interfaces, including default VLAN ID (PVID), accepted

frame types, and ingress filtering.

Command attributes

Command Attribute

PVID The VLAN ID assigned to untagged frames received on the interface. If the

(CLI) switchport mode is set to "trunk" (" switchport mode" (pg.179) in

"4.2.13 VLAN Commands" (pg.115)), the PVID will be inserted into all

untagged frames sent from a tagged port (Default: 1).

Note:

If the interface is not a member of VLAN 1 (VLAN ID = 1), when

VLAN 1 is assigned to the interface's PVID, the interface is

automatically added to VLAN 1 as an untagged member. For the other VLAN, before assigning PVID, interfaces must be

added to the VLAN as untagged member.

If "Acceptable Frame Type" is set to "ALL" (or "switchport mode" is

set to "Hybrid" in CLI), PVID will be inserted into all untagged frames

received at input ports.

Acceptable Frame Type Sets the interface so that it selects and accepts either all frame types

(including tagged or untagged frames), or only tagged frames. If set to accept

only tagged frames, the switch will only accept frames if the frame tag

matches a VLAN to which this interface has been assigned (Default: All).

Ingress Filtering If ingress filtering is enabled, incoming frames for VLANs which do not

include this input port in their member set will be discarded at the input port.

(Default: Disabled)

Note:

Ingress filtering affects only tagged frames.

When ingress filtering is disabled, if a tag matched the VLAN

recognized on the switch, the interface accepts all incoming tagged

VLAN frames (except for explicitly forbidden VLAN on this port).

If ingress filtering is enabled, incoming tagged VLAN frames that are

not included in the members of this input will be discarded.

Ingress filtering does not affect BPDU frames, such as STP that is

not related to VLAN.

Trunk Member Shows whether the port is included in the trunk members. To add a trunk for

selected VLAN, use the last table on the "VLAN Static Table" page.

3.12Multicast Configuration

This section explains the multicast configuration.

Multicasting

Multicasting is used to support real-time applications such as video conferencing or streaming audio.

A multicast server does not have to establish a separate connection with each client. A multicast server

broadcasts its service to the network and any hosts that receive the multicast register with their local

multicast switch/router. Although this approach reduces the network overhead required by a multicast

server, the broadcast traffic must be carefully pruned at every multicast switch/router it passes through to

ensure that traffic is only passed on to the hosts which use this service.

Multicast filtering

This switch uses Internet Group Management Protocol (IGMP) to check for any connected hosts that

want to receive a specific multicast service. Then, it identifies the ports containing hosts requesting to

join the service and sends data out to those ports only. Next, it propagates the service request up to any

neighboring multicast switch/router to ensure that it will continue to receive the multicast service. This

procedure is called multicast filtering.

The purpose of IP multicast filtering is to optimize a switched network's performance, so multicast

packets will only be forwarded to those ports containing multicast group hosts or multicast routers/

switches, instead of flooding traffic to all ports in the subnet (VLAN).

3.12.1 Configuring IGMP Parameters

You can configure the switch to forward multicast traffic intelligently. Based on the IGMP query and

report messages, the switch forwards traffic only to the ports that request multicast traffic. This prevents

the switch from broadcasting the traffic to all ports and possibly disrupting network performance.

Command Usage

• IGMP Snooping

This switch can passively snoop on IGMP Query and IGMP Report packets transferred between IP

multicast routers/switches and IP multicast host groups to identify the IP multicast group members. It

simply monitors the IGMP packets passing through it, picks out the group information, and

configures multicast filters accordingly.

• IGMP Query

A router, or multicast-enabled switch, can periodically ask their hosts if they want to receive

multicast traffic. If there is more than one router/switch on the LAN performing IP multicasting, one

of these devices is selected as the "querier device" and assumes the role of querying the LAN for

group members. Next, it propagates the service request up to any neighboring multicast switch/router

to ensure that it will continue to receive the multicast service.

Snooping (Default: Disabled).

Act as IGMP Querier When enabled, the switch can serve as the "querier device", which is

responsible for asking hosts if they want to receive multicast traffic (Default:

Disabled).

IGMP Query Count Sets the maximum number of queries to be issued to a client that sends no

response, before the switch takes action to delete the client (Default: 2,

Range: 2–10).

IGMP Query Interval Sets the frequency (in seconds) at which the switch sends IGMP host-query

messages (Default: 125, Range: 60–125).

IGMP Report Delay Sets the time (in seconds) after receiving an IGMP Report for an IP multicast

address on a port, before the switch sends an IGMP Query to the port and

removes the entry from its list (Default: 10, Range: 5–30).

IGMP Query Timeout Sets the time (in seconds) the switch waits after the previous querier device

has stopped querying, before the interface that received query packets

recognizes that the querier device has been disconnected.

IGMP Version Sets the protocol version for compatibility with other devices on the network

(Default: 2, Range: 1–2).

Specifying Interfaces Connected to a Multicast Router

Depending on your network connections, IGMP snooping may not always be able to locate the IGMP

querier device. Therefore, if the IGMP querier device is a known multicast router/switch connected over

the network to an interface (port or trunk) on the switch, you can manually configure that interface to

join all the current multicast groups. This can ensure that multicast traffic is passed to all the appropriate

interfaces within the switch.

Note that the number of multicast router ports that can be configured is up to 32, including the ports

automatically configured by IGMP snooping.

3.13.2 Configuring Interface Connections

The following can be set by using the Trunk Configuration page or Port Configuration page:

• To enable/disable an interface, manually set the speed and duplex mode

• Set flow control

• Set auto-negotiation

• Set interface capabilities to advertise

Command attributes

When auto-negotiation is enabled, the Switch Blade performs optimal settings for each

link. When it is disabled, be sure to manually set the [Speed/Duplex Mode] and [Flow

Control] options.

Command Attribute

Name Interface label can be specified (range: 1- 64 characters).

Admin Interface can be manually disabled. When an abnormality occurs (e.g.

excessive collisions occur), interface can be once disabled, and enabled

again after the problem is solved. In addition, interface may be disabled due

to a security reason.

Speed/Duplex When auto-negotiation is disabled, port speed and duplex mode can be

manually selected.

Flow Control Allows automatic or manual selection of flow control.

• Flow control can eliminate frame loss by "blocking" traffic sent from end

stations or segments connected directly to the switch when its buffers fill.

When flow control is enabled, back pressure is used for half-duplex

operation and IEEE 802.3x for full-duplex operation.

• Flow control should not be used for a port connected to a hub, unless it is

necessary to solve a problem. Doing so may reduce network performance

because the flow control affects segments connected to the hub.

Note:

To enable flow control between an uplink port and internal port,

specify "flowcontrol" for the uplink port function list, and "symmetric"

for the internal port function list.

Autonegotiation/Port

Capabilities

Sets auto-negotiation to be enabled or disabled. Specify the capabilities that

each port supports for auto-negotiation. The following capabilities are

supported. However, note that the internal ports (1 -10) are fixed to

1000Mbps and full-duplex mode.

• 10half: supports 10Mbps half-duplex operation.

• 10full: supports 10Mbps full-duplex operation.

• 100half: supports 100Mbps half-duplex operation.



• Sym: sends/receives pause frames for flow control.

• FC: supports flow control.

Trunk Shows whether the port is included among the trunk members. When

creating a trunk and selecting port members, refer to "3.15 Port Trunk

Configuration" (pg.94).

3.13.3 Setting Broadcast Storm Thresholds

Broadcast storms may occur when a device on the network is malfunctioning, or if application programs

are not well designed or properly configured. If there is too much broadcast traffic on the network,

performance can be severely degraded, or everything on the network can temporarily come to a

complete halt.

You can protect the network from broadcast storms by setting a threshold for broadcast traffic for each

port. Any broadcast packets exceeding the specified threshold will be discarded.

Command Usage

• Broadcast storm control is disabled by default.

• Broadcast control does not affect IP multicast traffic.

• The specified thresholds will be applied to the entire switch.

Web UI

1 Click [Port], and then [Broadcast Control].

2 Select a threshold, and then click [Apply].

The threshold can be selected from among 16, 64, 128, 256 packets/second (PPS).

3.14Configuring Port Mirroring

You can mirror traffic from a source port that monitors traffic to a target port for real-

time analysis. In addition, if you attach a logic analyzer or RMON probe to the target

port, you can study the traffic crossing the source port in a completely unobtrusive

manner.

Command Usage

The source port and monitor port speed must match. Otherwise traffic may be dropped from the monitor

port.

Web UI

1 Click [Mirror].

2 Specify the source port, the traffic type to be mirrored, and the monitor port, and

then click [Add].

CLI

After selecting a monitor port using the "interface" command, specify the source port using "port

monitor" command. Note that the CLI default mirroring is performed for both transmitting and receiving

packets.

3.15Port Trunk Configuration

Ports can be combined into an aggregate link to increase the bandwidth of a network

connection where bottlenecks exist or to ensure fault recovery. You can configure

trunks between any two switches of the same type. Uplink ports 11-12 on this switch

can be grouped into a trunk, creating an aggregate bandwidth up to 4 Gbps when

operating in full duplex mode.

Besides balancing the load across each port in the trunk, the additional port provides redundancy by

taking over the load if another one of the trunk ports fails. Before making any physical connections

between devices, use the Web UI or CLI to specify the trunk on the devices at both ends. When using a

port trunk, note the following points:

• Finish configuring port trunks before you connect the corresponding network cables between

switches to avoid creating a loop.

• Only the uplink ports 11 -12 can configure a trunk group.

• The ports at both ends of a connection must be configured as trunk ports.

• The ports at both ends of a trunk must be configured in an identical manner, including

communication mode (i.e., speed, duplex mode, and flow control), VLAN assignments, and CoS

settings.

• All the ports in a trunk must be treated as a whole when moved from/to, added or deleted from a

VLAN.

• STP, VLAN, and IGMP settings can only be set for the entire trunk.

3.16Displaying Device Statistics

You can display standard statistics on network traffic from the Interfaces Group MIB

and Ethernet-like MIB, as well as detailed information of traffic based on the RMOM

MIB. Interfaces MIB and Ethernet-like MIB statistics display errors on the traffic

passing through each port. This information can be used to identify potential

problems with the switch (such as a faulty port or unusually heavy loading).

RMON statistics can display a broad range of statistics, including a total count of

various frame types and sizes passing through each port. All values displayed have

been accumulated since the last system reboot, and are shown as counts per

second. By default, the statistics are updated every 60 seconds.

RMON groups 2, 3, and 9 can only be displayed when using SNMP management software.

4.1 Usage of the Command Line Interface

4.1.1 Accessing the CLI

When the management station (management terminal) accesses the management interface of the switch

via a connection through Management Blade to console port, or via a Telnet connection, the switch can

be operated by entering command keywords and parameters at the prompt. Using the switch's command-

line interface (CLI) is very similar to entering commands on a UNIX system.

Console Connection

To access the switch through the console port, use the console redirection function of the Management

Blade.

1 Access the Management Blade CLI.

→ "BX600 S2 Blade Server System Unit Hardware Guide"

2 Display the Switch Blade console redirection screen from the Management

Blade menu.

3 Select "Console Redirection" from "Console Menu" to select the Switch Blade

to access.

"Console>" prompt will appear and the normal access mode (Normal Exec) starts.

In this mode, switch's configuration information can be displayed.

To change the configuration, the "enable" command must be entered. "Console#" prompt will

appear and the privileged access mode (Privileged Exec) starts.

4 Enter the necessary commands to execute tasks.

5 When finished, exit the session with the "quit" or "exit" command.

6 Press the return hot key to exit the console redirection screen.

The return hot key is [Ctrl] + [Q] by default. For details, refer to "BX600 Management Blade

Hardware Guide 5.4.3 Console Redirection".

User Access Verification

CLI session with the Switch Blade is opened.

To end the CLI session, enter [Exit].

Telnet connection

Telnet operates over the IP transport protocol. In this environment, the management station and any

network device you want to manage over the network must have valid IP addresses. Valid IP addresses

consist of four numbers, 0 to 255, separated by periods.

Each address consists of a network portion and host portion. For example, the default IP address

assigned to this switch, 10.1.0.1, consists of a network portion (10.1.0) and a host portion (1).

IP address is not assigned to the switch by default. You must set a new IP address for the switch. To

access the switch through a Telnet session, you must first set the IP address for the switch. In addition,

when you operate the switch from a different IP subnet, set the default gateway.

For example, if your corporate network is connected to another network outside your office, or to the

Internet, you need to apply for a registered IP address. However, if you are connected to an isolated

network, then you can use any IP address that matches the network segment to which you are connected.

After you configure the switch with an IP address, you can open a Telnet session by performing these

steps.

1 From the remote host, enter the Telnet command and the IP address of the

device you want to access.

2 At the prompt, enter the user name and system password.

The default user names are "admin" and "guest", and the respective passwords are also "admin"

and "guest".

The Login window appears.

The CLI will display the "Vty-0#" prompt for the administrator to show that you are using

privileged access mode (i.e., Privileged Exec), or "Vty-0>" prompt for the guest to show that you

are using normal access mode (i.e., Normal Exec).

3 Enter the necessary commands to execute tasks.

4 When finished, exit the session with the "quit" or "exit" command.

You can open 4 sessions from Telnet.

4.1.2 Setting a Password

If this is the first time to login to the configuration program, you should define a new password using

the "username" command, record it and keep it in a safe place.

Passwords can consist of up to 8 alphanumeric characters and are not case sensitive. To prevent

unauthorized access to the switch, set the passwords as follows:

1 Open the console interface and enter the "enable" command to access the

privileged access mode.

2 Enter "configure" and press the [Enter] key.

The global configuration mode prompt will appear.

3 Enter "username admin password 0 password" for the "Privileged Exec" level.

This "password" means a new password. Press the [Enter] key. Change the password for the

"Normal Exec" level in the same manner.

4 Enter "exit" and press the [Enter] key.

5 Enter "copy running-config startup-config" and press the [Enter] key.

The configuration change is saved.

CLI configuration commands only modify the running configuration file and are not saved

when the switch is rebooted. To save all your configuration changes in nonvolatile

memory, you must copy the running configuration file to the startup configuration file using

the copy command.

4.1.3 Setting an IP Address

IP address is not assigned to the switch by default. You must set a new IP address for the switch. You

may also need to establish a default gateway between this device and management stations that exist on

another network segment. You can manually configure a specific IP address, or set the device to obtain

an address from a BOOTP or DHCP server. Valid IP addresses consist of four decimal numbers, 0 to

255, separated by periods. Anything outside this format will not be accepted by the CLI program.

The IP address for this switch is not specified by default. The default management interface is VLAN 1.

If you select the "bootp" or "dhcp" option, IP is enabled but will not function until a BOOTP or DHCP

reply has been received. Requests will be broadcast periodically by this device in an effort to learn the IP

address (BOOTP and DHCP values can include the IP address, default gateway, and subnet mask).

Before you assign an IP address to the switch, you must obtain the following information from the

network administrator:

• IP address for the switch

• Default gateway for the network

• Network mask for this network

To assign an IP address to the switch, complete the following steps:

1 From the Privileged Exec level global configuration mode prompt, enter

"interface vlan 1" to access the interface-configuration mode, and press the

[Enter] key.

2 Enter "ip address ip-address netmask".

"ip-address" is the switch IP address and "netmask" the network mask for the network.


Returns to the global configuration mode prompt.

4 When setting the IP address of the default gateway for the network to which the

switch belongs, enter "ip default-gateway gateway", and press the [Enter] key.

"gateway" is the IP address of the default gateway.


Console#config





Console(config)#

6 Enter "copy running-config startup-config" and press the [Enter] key.

The configuration change is saved.

At this point, you are ready to use appropriate network cabling to connect devices to the switch's

external RJ-45 connectors.

4.1.4 Entering Commands

This section describes how to enter CLI commands.

Keywords and Arguments

A CLI command is a series of keywords and arguments. Keywords identify a command and arguments

specify configuration parameters. For example, in the command "show interfaces status ethernet 1/5,"

show, interfaces, and status are keywords, ethernet is an argument that specifies the interface type, and 1/

5 specifies the unit-number/port-number.

Since this switch is a stand-alone device, the interface number and unit number are always "1". For

example, enter "1/5" for port 5.

Enter commands as follows:

• To enter a single command, enter the command keyword.

• To enter multiple commands, enter each command in the required order. For example, to enable

Privileged Exec command mode, and display the startup configuration, enter:

• To enter commands that require parameters, enter the required parameters after the command

keyword. For example, to set a password for the administrator, enter:

Command Abbreviation

The CLI uses a minimum number of characters that uniquely identify a command. For example, the

command "configure" can be entered as "config". If an entry is not sufficient to identify the command,

the system will prompt for further input.

Command Completion

When pressing the [Tab] key after typing a part of a keyword (unique word), CLI will print the

remaining characters of the keyword. For example, when the keyword is "configure", entering "config"

and pressing the [Tab] key makes CLI print "configure".

Help on Commands

You can display a brief explanation of the help system by entering the "help" command. You can also

display command syntax by using the "?" character to see a keyword list or parameter list.

Showing Commands

If you enter a "?" at the command prompt, the system will display the first level of keywords for the

current command class (Normal Exec or Privileged Exec) or configuration class (Global, Interface,

Line, VLAN Database). You can also display a list of valid keywords for a specific command. For

example, the command "show ?" displays a list of possible show commands:

The command "show interfaces ?" will display the following information:

Partial Keyword Lookup

If you terminate a partial keyword with "?", the remaining letters that may follow the initial letters are

provided (Remember not to leave a space between the command and "?"). For example, "s?" shows all

the keywords starting with "s".

Negating Command

For many configuration commands you can enter the prefix keyword "no" to cancel the effect of a

command or reset the configuration to the default value. For example, the "logging" command will log

system messages to a host server. To disable logging, specify the "no logging" command. This guide

describes the negation effect for all applicable commands.

Using Command History

The CLI maintains a history of commands that have been entered. You can scroll back through the

history of commands by pressing the up arrow key [↑]. Any command displayed in the history list can

be executed again, or first modified and then executed.

Using the "Show history" command displays a longer list of recently executed commands.

Command Modes

The command set is divided into Exec and Configuration classes. "Exec" commands generally display

information on system status or clear statistical counters. "Configuration" commands, on the other hand,

modify interface parameters or enable certain switching functions. These classes are further divided into

different modes. Available commands depend on the selected mode. You can always enter a question

mark "?" at the prompt to display a list of the commands available for the current mode. The command

classes and associated modes are displayed in the following table:

Exec Commands

When a user opens a new console session on the switch, the system enters Normal Exec command mode

(or guest mode). Only a limited number of the commands are available in this mode. You can access all

the commands in Privileged Exec command mode (or administrator mode). To access Privilege Exec

mode, enter the "enable" command (followed by the privileged level password if so configured). The

command prompt displays as "Console>" for Normal Exec mode and "Console#" for Privileged Exec

mode.

To enter Privileged Exec mode, enter the following commands:

Configuration Commands

Configuration commands are privileged level commands used to modify switch settings. These

commands modify the running configuration only, and are not saved when the switch is rebooted. To

store the running configuration in nonvolatile memory, use the "copy running-config", "startup-config"

commands.

The configuration commands are organized into three different modes:

• Global Configuration

These commands modify the system level configuration, and include commands such as "hostname"

and "snmp-server community".

• Interface Configuration

These commands modify the port configuration such as "speed-duplex" and "negotiation".

• Line Configuration

These commands modify the console port configuration, and include commands such as "parity" and

"databits".

To enter the Global Configuration mode, enter the "configure" command in Privileged Exec mode. The

system prompt will change to "Console(config)#", which gives you access privileges to all Global

Configuration commands.

To enter Interface, Line Configuration, or VLAN mode, you must enter the "interface ...", "line ...", or

"vlan database" command while in Global Configuration mode. The system prompt will change to

"Console(config-if)#", "Console(config-line)#", or Console(config-vlan#)", indicating that you have

access privileges to the associated commands. You can use the "end" command to return to the

Privileged Exec mode.

4.3.2 Flash/File Commands

These commands are used to manage the system code or configuration files.

Copy

Use this command to upload/download a firmware code image or configuration file between the switch's

Flash memory and a TFTP server. When you save the runtime code or configuration settings to a file on

a TFTP server, that file can later be downloaded to the switch to restore system operation. The success of

the file transfer depends on the accessibility of the TFTP server and the quality of the network

connection.

• Syntax

- file: Keyword that allows you to copy to/from a file.

- running-config: Keyword that allows you to copy to/from the current running configuration.

- startup-config: Sets up configuration used for system initialization.

- tftp: Keyword that allows you to copy to/from a TFTP server.

• Default Setting

None

• Command Mode

Privileged Exec

• Command Details

- Displays the system prompts for data required to execute the copy command.

- The destination configuration file name should not contain slashes (/) or backslashes (\), and the

leading character of the file name must not be a period (.). The file name must consist of 1 to 31

characters. Allowed characters are A - Z, a - z, 0 - 9, "." , "-", "_".

- The maximum number of user-defined configuration files depends on the memory size.

- You can use "Factory_Default_Config.cfg" as the copy source from the factory default

configuration file, but you cannot use "Factory_Default_Config.cfg" as the copy destination.

- To rewrite the startup configuration, you must use startup-config as the copy destination.

- The Boot ROM (diagnostic) image cannot be uploaded/downloaded to/from a TFTP server.

• Example

• Command Details

- This switch increases throughput for transmitting large continuous data, by supporting up to 9000

bytes jumbo frame. When using jumbo frames, you can significantly decrease overhead per packet

needed for capsulating the protocol data, compared with using a standard Ethernet frame that is up

to 1518 bytes.

- In order to use jumbo frames, the both source and destination end-nodes (terminals such as servers)

must support this function. In addition, when the network connection is full-duplex mode, all the

switches on the network that connect the two end-nodes must allow the extended size frames.

When the network is half-duplex connection, all devices within the collision domain must support

jumbo frame.

- When jumbo frame is enabled, the maximum buffer size for controlling broadcast storm is limited

to 64 packets.

• Command Details

If you do not enter an "snmp-server" command, no notifications are sent. In order to configure the

switch to send SNMP notifications, you must enter at least one "snmp-server host" command.

In order to enable multiple hosts, you must issue a separate "snmp-server host" command for each

host. The "snmp-server host" command is used in conjunction with the "snmp-server enable traps"

command.

Use the "snmp-server enable traps" command to specify which SNMP notifications are sent globally.

For a host to receive notifications, at least one "snmp-server enable traps" command and the "snmp-

server host" command for that host must be enabled.

However, some notification types cannot be controlled with the "snmp-server enable traps"

command.

For example, some notification types are always enabled.

• Example




Use this command to enable this device to send Simple Network Management Protocol traps or

information (SNMP notifications). Add the "no" form before the command to disable SNMP

notifications.

• Syntax

- authentication: Keyword to issue authentication failure traps

- link-up-down: Keyword to issue link-up or link-down traps

The link-up-down trap can only be enabled/disabled via the command line interface.

• Default Setting

Link-up-down (starts notification operations from 10 seconds after the completion of switch boot)

• Command Mode


Console(config)#snmp-server host 10.1.19.23 batman

Console(config)#

snmp-server enable traps [authentication | link-up-down]

no snmp-server enable traps [authentication | link-up-down]

141

• Command Details

If you do not enter an "snmp-server enable traps" command, no notifications controlled by this

command are sent. In order to configure this device to send SNMP notifications, you must enter at

least one "snmp-server enable traps command. If you enter the command with no keywords, all

notification types are enabled. If you enter the command with a keyword, only the notification type

related to that keyword is enabled.

The "snmp-server enable traps" command is used in conjunction with the "snmp-server host"

command. Use the "snmp-server host" command to specify which host or hosts receive SNMP

notifications. In order to send notifications, you must set at least one "snmp-server host" command.

The notification types used in this command all have an associated MIB object that allows them to be

globally enabled or disabled. Not all of the notification types have MIB objects that enable

notifications. Therefore, some of these cannot be controlled using the "snmp-server enable traps"

command.

• Example

4.3.5 Line Commands

You can access the onboard configuration program by using the console redirection function from the

Management Blade's CLI. By using line commands, the parameters for the serial port or virtual terminal

can be set. Telnet is regarded as virtual terminal connection, and only the "exec-timeout" and "password-

thresh" commands are used for Telnet.

line

Use this command to specify a target line for configuration. And then, process the line configuration

commands.

• Syntax

- console: Console terminal line

- vty: Virtual terminal for remote console access

• Default Setting

None

• Command Mode


Console(config)#snmp-server enable traps link-up-down

Console(config)#

The Switch Blade's serial ports are connected to the Management Blade, and they can access the

management program by the default settings. Do not change the line configuration for the serial

ports.

mand R

efe

rence

• Command Details

Telnet is regarded as virtual terminal connection, and will be shown as "vty" by the "show users"

command. However, the serial communication parameters (e.g., databits) do not affect Telnet

communication.

• Example

To enter console line mode, enter the following command:


show line

show users

login

Use this command to enable password checking at login. Add the "no" form before the command to

disable password checking and allow connections without a password.

• Syntax

- local: Selects local password checking.

Authentication is based on the user name specified with the "username" command.

• Default Setting

By default, virtual terminals require a password. If you do not set a password for a virtual terminal, it

will respond to attempted connections by displaying an error message and closing the connection.

• Command Mode

Line Configuration

• Command Details

If you specify login without the local option, authentication is based on the password specified with

the "Line configuration" command.

• Example


username

password

Console(config)#line console


login [local]

no login

Console(config-line)#login local

password

Use this command to specify the password for a line. Add the "no" form before the command to remove

the password.

• Syntax

- 0 | 7: 0 means plain password, 7 means encrypted password.

- password: String that specifies the password.

(Maximum number of characters: 8 for plain password, 32 for encrypted password)

• Default Setting

No password is specified.

• Command Mode

Line Configuration

• Command Details

- When a connection is started on a line with password protection, the system requires a password

entry.

If you enter the correct password, the system shows a prompt. You can use the "password-thresh"

command to set the number of times a user can enter an incorrect password. If the number of

incorrect entries exceeds the threshold, the system terminates the line connection and returns the

terminal to the idle state.

- When you try to display the contents of the configuration file while the system is running, or try to

display the contents of the configuration file downloaded from TFTP server, the password shown

on the screen will be encrypted. The password encryption option is used for decoding the

encrypted password. When setting a new password, you do not need to specify an encrypted

password using the command option.

• Example

• Default Setting

CLI: No timeout

Telnet: 600 seconds

• Command Mode

Line Configuration

• Command Details

- If input is detected, the system resumes the current connection. If no connections exist, it returns

the terminal to the idle state and disconnects the next session.

- This command is applied to both local console and Telnet connection.

- The timeout setting for Telnet cannot be canceled.

• Example

To set the timeout to two minutes, enter this command:

password-thresh

Use this command to set the password intrusion threshold which limits the number of failed logon

attempts. Add the "no" form before the command to remove the threshold value.

• Syntax

- threshold: The number of allowed password attempts (Range: 1 - 120; 0: no threshold)

• Default Setting

silent-time

Use this command to set the amount of time the operation console is inaccessible after the number of

unsuccessful logon attempts exceeds the threshold set by the "password-thresh command". Add the "no"

form before the command to cancel the silent-time value.

• Syntax

- seconds: The number of seconds the console remains silent (Range: 0-65535; 0: no silent-time)

• Default Setting

None

• Command Mode

Line Configuration

• Command Details

If the password threshold was not set with the password-thresh command, silent-time begins after the

default value of three failed logon attempts.

• Example

To set the silent time to 60 seconds, enter this command:


password-thresh

databits (must not be changed: usually will not be used)

Use this command to set the number of data bits per character that are interpreted and generated by the

console port. Add the "no" form before the command to restore the default.

• Syntax

- 7: Seven data bits per character.

- 8: Eight data bits per character.

• Default Setting

8 data bits per character.

• Command Mode

Line Configuration

• Command Details

The "databits" command can be used to mask the high bit on input from devices that generate 7 data

bits with parity. If parity is being generated, specify 7 data bits per character. If no parity is required,

specify 8 data bits per character.

• Example

To specify 7 data bits, enter this command:

4.3.8 IP Commands

IP address of this switch is not assigned by default. A new IP address needs to be manually set as

necessary. You also need to establish a default gateway between this device and management stations

that exist on another network segment.

ip address

Use this command to set an IP address for this device. Add the "no" form before the command to restore

the default IP address.

• Syntax

- ip-address: IP address

- netmask: Network mask for the associated IP subnet. This mask identifies the host address bits

used for routing to specific subnets.

- bootp: Obtains IP address from BOOTP.

- dhcp: Obtains IP address from DHCP.

• Default Setting

IP address: 0.0.0.0

netmask: 255.0.0.0

• Command Mode

Interface Configuration (VLAN)

• Command Details

- You must assign an IP address to this device to gain management access over the network. You can

manually configure a specific IP address, or set the device to obtain an address from a BOOTP or

DHCP. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. Anything

outside this format will not be accepted by the configuration program.

- If you select the "bootp" or "dhcp" option, IP is enabled but will not function until a BOOTP or

DHCP reply has been received. Requests will be broadcast periodically by this device in an effort

to learn its IP address. (Using DHCP or BOOTP, values of the IP address, default gateway, and

subnet mask can be set.)

- To start broadcasting requests, enter the "ip dhcp restart" command or restart the switch.

IP address is assigned to only one VLAN (Management VLAN). Therefore, to use VLAN, the

management station must be connected to a port that is included in Management VLAN.

When you assign an address to any VLAN, the original IP address is immediately disabled, and the

new address takes effect.

• Example

In the following example, the device is assigned an address in VLAN 1.


ip dhcp restart

ip address ip-address netmask | bootp | dhcp

no ip address



Console(config-if)#

161

1


ip dhcp restart

Use this command to send a BOOTP or DCHP client request.

• Default Setting

None

• Command Mode

Privileged Exec

• Command Details

- Requires the DHCP server to reassign the client address.

- If the BOOTP or DHCP server has been moved to a different domain, the network portion of the

client address will be based on this new domain.

• Example

In the following example, the device is reassigned the same address.


ip address

ip default-gateway

Use this command to establish a static route between this device and management stations that exist on

another network segment. Add the "no" form before the command to remove the static route.

• Syntax

- gateway: IP address of the default gateway

• Default Setting

No default gateway is established.

• Command Mode


• Command Details

A gateway must be defined if the management station is located in a different IP segment from the

Switch Blade.

• Example

The following example defines a default gateway for this device:



and address mode: Dhcp.

ping

Use this command to send ICMP echo request packets to another node on the network.

• Syntax

- host: IP address for the host.

- count: Number of packets to send (Range: 1–16, default: 5).

- size: Number of bytes in a packet (Range: 32–512, default: 32 bytes). The actual packet size will

be eight bytes larger than the size specified because the switch adds header information.

• Default Setting

This command has no default IP address for the host.

• Command Mode


• Command Details

- Use the "ping" command to see if another terminal on the network can be reached.

- Following are some results of the ping command:

• Normal response: The normal response occurs in one to ten seconds, depending on network

traffic.

• Destination does not respond: If the host does not respond, "timeout" is displayed.

• Destination unreachable: The gateway for this destination indicates that the destination is

unreachable.

• Network or host unreachable: The gateway found no corresponding entry in the route table.

- Press the [Esc] key to exit the "ping" command.

• Example

4.3.9 Mirror Port Commands

This section explains how to mirror traffic from a source port to a destination port.

port monitor

Use this command to configure mirroring. Add the "no" form before the command to remove mirroring.

• Syntax

- interface: ethernet unit/port (source port)



- rx: Mirroring for receiving packets

- tx: Mirroring for sending packets

- both: Mirroring for sending/receiving packets

• Default Setting

No mirroring is defined. When enabled, the default mirroring is for both receiving and sending

packets.

• Command Mode

Interface Configuration (Ethernet, destination port)

• Command Details

- You can mirror traffic from any source port to a destination port for real-time analysis. You can

attach a logic analyzer or RMON probe to the destination port and study the traffic crossing the

source port in a completely unobtrusive manner.

- The destination port is set by specifying an Ethernet interface.

- Only one mirror session can be specified. When multiple mirror sessions are specified, a command

error occurs.

• Example

The following example configures the switch to mirror all packets from port 6 to port 11:


show port monitor

bridge spanning-tree

Use this command to enable the spanning tree algorithm globally for this switch. Add the "no" form

before the command to disable it.

• Syntax


• Default Setting

Enabled

• Command Mode


• Command Details

The Spanning Tree Algorithm can be used to detect and disable network loops, and to provide backup

links between switches, bridges, or routers. This allows the switch to interact with other bridging

devices (that is, an STA compliant switch, bridge, or router) in the network, to ensure that only one

route exists between any two stations on the network, and provide backup links which automatically

take over when a primary link goes down.

• Example

The following example shows how to enable the spanning tree algorithm for this switch:

bridge forward-time

Use this command to configure the spanning tree bridge forward-time globally for this switch. Add the

"no" form before the command to restore the default.

• Syntax


- seconds: Time in seconds. (Range: 4–30 seconds)

The minimum value is the higher of 4 or [(max-age / 2) + 1].

• Default Setting

15 Seconds

• Command Mode


• Command Details

This command sets the maximum time (in seconds) the root bridge will wait before changing states

(i.e., listening to learning to forwarding). This delay is required because every device must receive

information about topology changes before starting to forward frames. In addition, each port needs

time to receive conflicting information that would make it return to a blocking state. Otherwise,

temporary data loops might result.

• Example

bridge hello-time

Use this command to configure the spanning tree bridge hello time globally for this switch. Add the "no"

form before the command to restore the default.

• Syntax


- time: Time in seconds (Range: 1–10 seconds)

The maximum value is the lower of 10 or [(max-age / 2)–1].

• Default Setting

2 Seconds

• Command Mode


• Command Details

This command sets the time interval (in seconds) at which the root device transmits a configuration

message.

• Example

bridge max-age

Use this command to configure the spanning tree bridge max-age globally for this switch. Add the "no"

form before the command to restore the default.

• Syntax


- seconds: Time in seconds (Range: 6–40 seconds)

The minimum value that can be set is the longer of 6 or [2 × (hello-time + 1)].

The maximum value that can be set is the shorter of 40 or [2 × (forward-time - 1)].

• Default Setting

• Command Details

This command sets the maximum time (in seconds) a device can wait without receiving a

configuration message before attempting to reconfigure. All ports (except for designated ports)

should receive configuration messages at regular intervals. Any port that ages out STA information

(provided in the last configuration message) becomes the designated port for the attached LAN. If it

is a root port, a new root port is selected from among the device ports.

• Example

bridge priority

Use this command to configure the spanning tree priority globally for this switch. Add the "no" form

before the command to restore the default.

• Syntax


- priority: Priority of the bridge (Range: 0–65535)

• Default Setting

32768

• Command Mode


• Command Details

Bridge priority is used in selecting the root device, root port, and designated port. The device with the

highest priority (i.e. the lowest priority value) becomes the STA root device. However, if all devices

have the same priority, the device with the lowest MAC address will then become the root device.

• Example

bridge-group path-cost

Use this command to configure the spanning tree path cost for the specified port. Add the "no" form

before the command to restore the default.

• Syntax


- cost: The path cost for the port. (Range: 1-65535)

Recommended range:

• Ethernet (10Mbps): 50–600

• Fast Ethernet (100Mbps): 10–60

• Giga-bit Ethernet: 3–10

• Default Setting

- Ethernet: half-duplex: 100, full-duplex: 95, trunk: 90

- Fast Ethernet (100Mbps): half-duplex: 19, full-duplex: 18, trunk: 15

- Giga-bit Ethernet: full-duplex: 4, trunk: 3

• Command Mode


• Command Details

- This command is used by the spanning-tree algorithm to determine the best path between devices.

Therefore, lower values should be assigned to ports attached to faster media, and higher values

assigned to ports with slower media.

- Path cost takes precedence over port priority.

• Example

bridge-group priority

Use this command to configure the priority for the specified port. Add the "no" form before the

command to restore the default.

• Syntax


- priority: The priority for an interface (Range: 0 - 255)qaqqa

• Default Setting

128

• Command Mode


• Command Details

- This command defines the priority for the use of a port in the spanning-tree algorithm. If the path

cost for all ports on a switch are the same, the port with the highest priority (that is, lowest value)

will be configured as an active link in the spanning tree.

- Where more than one port is assigned the highest priority, the port with the lowest port number will

be enabled.

• Example


Console(config-if)#bridge-group 1 path-cost 50

Console(config-if)#

bridge-group bridge-group priority priority

bridge-group portfast

Use this command to set "fast forward" to an interface. Add the "no" form before the command to

disable "fast forward".

• Syntax


• Default Setting

Ports 1 - 10: Enabled

Ports 11 - 13: Disabled

• Command Mode


• Command Details

- This command is used to enable/disable Fast Forward for the selected interface. In this mode, ports

skip the Blocked, Listening, and Learning states and change to Forwarding state.

- Since end-nodes cannot create forwarding loops, they can pass through the spanning tree state

changes more quickly than the standard convergence time. "Fast forward" can achieve quicker

convergence for end-node workstations and servers, and also overcome other STA related timeout

problems. (Remember that "fast forward" should only be enabled for ports connected to an end-

node device.)

- Set "Enable" for ports 1–10.

4.3.12 Priority Commands

The commands described in this section allow you to specify which data packets have greater

precedence when traffic is buffered in the switch due to access congestion. This switch supports CoS

that allows four priority queues for each port. Data packets in a high priority queue for a port are

transmitted sooner than data packets in a low priority queue. Default priorities can be set for each

interface. A map between the frame priority tags and the switch priority queues can be configured.

switchport priority default

Use this command to set priority for incoming untagged frames, or the priority of frames received by the

device connected to the specified interface. Add the "no" form before the command to restore the

default.

• Syntax

- default-priority-id: The priority number for untagged ingress traffic (Range: 0 - 7). Seven is the highest priority.

• Default Setting

The priority is not set. The default value for untagged frames received on the interface is zero. The

switch operation does not change due to priority.






VLAN learning: IVL




Global GVRP status: Disabled

GMRP: Disabled

Console#

switchport priority default default-priority-id

• Command Mode


• Command Details

- The default port priority applies if the incoming frame is an untagged frame received from a

VLAN trunk or a static-access port. This priority does not apply to IEEE 802.1Q VLAN tagged

frames. If the incoming frame is an IEEE 802.1Q VLAN tagged frame, the IEEE 802.1p User

Priority bits will be used.

- This switch provides four priority queues for each port. It is configured to use Weighted Round

Robin. Inbound frames that do not have VLAN tags are tagged with the input port's (default)

ingress user priority, and then placed in the appropriate priority queue at the output port. The

default priority for all input ports is zero. Therefore, any inbound frames that do not have priority

tags will be placed in queue 0 of the output port. (Note that if the output port is an untagged member of the associated VLAN, these frames are

stripped of all VLAN tags prior to transmission.)

• Example

The following example shows how to set a default priority "5" on port 3:

queue cos-map

Use this command to assign class of service (CoS) values to the CoS priority queues. Add the "no" form

before the command to set the default values to the CoS map.

• Syntax

- queue_id: The queue id of the CoS priority queue (Range: 0–3)

3 is the highest CoS priority queue.

- cos1 .. cosn: The CoS values that are mapped to the queue id (Range: 0–7)

This is a space-separated list of numbers. 7 is the highest priority.

• Default Setting

This switch supports Class of Service by using four priority queues, with Weighted Round Robin for

each port. Up to 8 separate traffic classes are defined in IEEE 802.1p. The default priority levels are

assigned according to recommendations in the IEEE 802.1p standard, as shown in the following

table.

4.3.13 VLAN Commands

VLAN is a group of ports, which can be set in any location on the network. The ports in one VLAN

communicate with each other as if they belong to a single physical segment. This section explains

commands that are used for creating VLAN, adding port members, and specifying how to use VLAN

tags.

vlan database

Use this command to enter VLAN database mode. All commands in this mode will take effect

immediately.

• Default Setting

None

• Command Mode


• Command Details

- Use the "VLAN database" command mode to add, change, and delete VLANs. After finishing

configuration changes, you can display the VLAN settings by using the "show vlan" command.

- Use the "interface vlan" command mode to define the port membership mode, and add or remove

ports from a VLAN. The results of these commands are written to the current configuration file,

and you can display this file by using the "show running-config" command.

• Example


show vlan

• When using the VLAN function of the Switch Blade to split the network into 2 or more, a server

blade cannot be installed to server blade slot 5 in the chassis. The maximum number of server

blades that can be installed is 9.

• The Spanning Tree function of this switch works regardless of the VLAN configuration.

Therefore, if network groups are configured, all ports except for one port are disabled, even if

they belong to different VLANs, so the VLANs to which the disabled ports belong may not be

able to communicate.

When using VLAN and configuring network groups, disable Spanning Tree.

shutdown

switchport ingress-filtering

Use this command to enable ingress filtering for an interface. Add the "no" form before the command to

restore the default.

• Syntax

• Default Setting

Disabled

• Command Mode


• Command Details

- Ingress filtering affects only tagged frames.

- When ingress filtering is disabled, if a tag matches the VLAN recognized on the switch, the

interface accepts all incoming tagged VLAN frames (except for VLAN explicitly forbidden on this

port).

- If ingress filtering is enabled, incoming tagged VLAN frames that are not included in the members

of this input port will be discarded.

- Ingress filtering does not affect BPDU frames, such as STP that is not related to VLAN.

• Example

The following example shows how to set the interface to port 1 and then enable ingress filtering:

interface vlan vlan-id



Console(config-if)#

switchport ingress- filtering

switchport acceptable-frame-types

Use this command to configure the acceptable frame types for a port. Add the "no" form before the


• Syntax

- all: All frames pass through the port regardless of whether tagged or untagged.

- tagged: Only tagged frames pass through the port.

• Default Setting

all

• Command Mode


• Command Details

- When a port is connected to a VLAN-aware device at the other end of a VLAN trunk, set the port

to accept only tagged frames. Otherwise, you must configure the port to accept all frame types.

- This command and the "switchport mode" command have the same capabilities.

• Example

The following example shows how to restrict the traffic received on port 1 to tagged frames:


switchport mode

switchport mode

Use this command to configure the VLAN membership mode for a port. Add the "no" form before the


• Syntax

- trunk: Specifies a port as an end-point for a VLAN trunk. Since trunk is a direct link between two

switches, ports sends/receives tagged frames that identify the transmission source VLAN.

- hybrid: Keyword that specifies a hybrid VLAN interface. The port can receive or transmit tagged

or untagged frames. Untagged frames are assigned to the default VLAN.

• Default Setting

All ports are in hybrid mode with the PVID set to VLAN 1.

• Command Mode


• Command Details

This command and the "switchport acceptable-frame-types" command have the same capabilities.

• Example

The following shows how to set port 1 to the configuration mode, and then set the switchport mode to

hybrid:


switchport acceptable-frame-types

switchport allowed vlan

Use this command to configure a VLAN group for selected interfaces. Add the "no" form before the


• Syntax

- add vlan-id: VLAN identifier to be added

- remove vlan-id: VLAN identifier to be removed (Range: 1-4094, no leading zeroes)

• Default Setting

All ports are assigned to VLAN 1 by default.

The default frame type is untagged.

• Command Mode


• Command Details

- When setting "switchport mode" to trunk, a VLAN group can be set only as a tagged member of

the interface.

- Frames will always be tagged in the switch. The tagged | untagged parameter is used for setting

whether the VLAN that is added at an interface retains or removes the tag attached to the frame.

- If this interface is connected to a VLAN-non-aware device, add all supported VLANs to the

interface as untagged members. Otherwise, at least one untagged VLAN must be added. In

addition, an added VLAN must match "native VLAN" for the interface.

- When you manually add a VLAN that is in the forbidden list of the interface using this command,

the VLAN is automatically removed from the forbidden list of the interface.

• Example

The following example shows how to add VLANs 1, 2, 5 and 6 to the allowed list as tagged VLANs

for port 1:


Console(config-if)#switchport mode hybrid

switchport native vlan

Use this command to configure the PVID (default VID) for a port. Add the "no" form before the


• Syntax

- vlan-id: Default VLAN ID for a port (Range: 1–4094, no leading zeroes)

• Default Setting

VLAN 1

• Command Mode


• Command Details

- If the interface is not a member of VLAN 1 (VLAN ID = 1), when VLAN 1 is assigned to the

interface's PVID, the interface is automatically added to VLAN 1 as an untagged member. For the other VLAN, before assigning PVID, interfaces must be added to the VLAN as untagged

members.

- If "acceptable frame types" is set to "all" or "switchport mode" is set to "hybrid", PVID will be

inserted into all untagged frames received at input ports.

• Example

The following example shows how to set VLAN 3 to the PVID of port 1:

switchport forbidden vlan

Use this command to configure forbidden VLANs.

Add the "no" form before the command to remove the list of forbidden VLANs.

• Syntax

- add vlan-id: VLAN identifier to be added

- remove vlan-id: VLAN identifier to be removed (Range: 1-4094, no leading zeroes)

• Default Setting

No VLANs are registered in the forbidden list.

• Command Mode


• Command Details

- This command prevents VLANs from being automatically added to a specified interface via GVRP

(GVRP is not supported).

- When a VLAN is added to an interface as "allowed VLAN", the VLAN cannot be added to the

forbidden VLAN list of the same interface.

4.3.14 Port Trunking Commands

By using trunk configuration, ports increase the bandwidth of a network connection or recover from a

failure. You can configure trunks between any two switches of the same type. Uplink ports 11-12 on this

switch can be grouped into a trunk, creating an aggregate bandwidth up to 4 Gbps when operating in

full-duplex mode.

channel-group

Use this command to add a port to a trunk. Add the "no" form before the command to remove a port

from a trunk.

• Syntax

- channel-id: The current port will be added to this trunk.

• Default Setting

No port has been set for a new trunk.

• Command Mode

Interface Configuration (Ethernet)

• Command Details

- Configure a trunk for ports before you connect the corresponding network cables between

switches, to avoid creating a loop.

- This switch supports only one trunk that contains ports 11 and 12.

- All links in a trunk must operate at the same transmission rate and the same duplex mode.

- You can link two switches of the same type only.

- A trunk must be set for the ports at both ends of a connection.

- The ports at both ends of a trunk must be configured in an identical manner, including

communication mode (i.e., transmission rate, duplex mode, and flow control), VLAN assignments,

and CoS settings.

- All the ports in a trunk must be treated as a whole when setting VLAN participation/

nonparticipation or addition/deletion.

- STP, VLAN, and IGMP settings can only be set for the entire trunk.

• Example

In the following example, trunk 1 is created with ports 11 and 12. To create a trunk, connect these

ports to 2 static trunk ports on another switch.

4.3.15 IGMP Snooping Commands

This switch uses Internet Group Management Protocol (IGMP) to check for any hosts that want to

receive a specific multicast service.

It identifies the ports containing hosts requesting the service, and sends data out to those ports only.

Then, it sends the service request to a nearby multicast switch/router, to make sure to continue receiving

the multicast service.

ip igmp snooping

Use this command to enable IGMP snooping on this switch. Add the "no" form before the command to

disable it.

• Syntax

• Default Setting

Disabled

• Command Mode


• Example

The following example enables IGMP snooping.

ip igmp snooping vlan mrouter

Use this command to statically configure a multicast router port. Add the "no" form before the command

to remove the configuration.

• Syntax

rence

• Command Details

- Depending on your network connections, IGMP snooping may not always be able to identify the

IGMP querier device. Therefore, if the IGMP querier device is a known multicast router/switch

connected over the network to an interface (port or trunk) on the switch, you can manually

configure that interface to be connected to all the current multicast groups.

Note that the number of multicast router ports that can be configured is up to 32, including the

ports automatically configured by IGMP snooping.

- This switch supports up to 32 multicast router interfaces, consisting of interfaces automatically

configured by IGMP snooping and interfaces manually configured.

• Example

The following shows how to configure port 11 as a multicast router port within VLAN 1:

ip igmp snooping vlan static

Use this command to add a port to a multicast group. Add the "no" form before the command to remove

the port.

• Syntax

- vlan-id: VLAN ID (Range: 1–4094)

- ip-address: IP address for multicast group

- interface



- port: Port number


• Default Setting

None

• Command Mode


• Command Details

This switch supports up to 64 multicast service groups, consisting of interfaces automatically


• Example

The following shows how to statically configure a multicast group on a port:

ip igmp snooping querier

Use this command to enable the switch as an IGMP snooping querier device. Add the "no" form before

the command to disable it.

• Syntax

• Default Setting

Disabled

• Command Mode


• Command Details

If enabled, the switch will serve as querier device if selected. The querier device is responsible for

asking hosts if they want to receive multicast traffic.

• Example

ip igmp snooping query-count

Use this command to set the query count. Add the "no" form before the command to restore the default.

• Syntax

- count: the maximum number of queries to be issued to a client that sends no response, before the

switch takes action to delete the client (Range: 2–10).

• Default Setting

2

• Command Mode


• Command Details

"query count" specifies how long the querier device waits for a response from a multicast client.

When the client sends no response even after the querier device has issued the number of queries

specified by this command, the querier device takes action after the countdown timer shows the time

specified by "ip igmp snooping query-max-response-time". If the client sent no response by the time

the timer has counted down, the client is removed from the multicast group.

• Example

The following shows how to set the query count to 10:


ip igmp snooping query-max-response-time

ip igmp snooping querier

no ip igmp snooping querier

Console(config)#ip igmp snooping querier

• Default Setting

125 Seconds

• Command Mode


• Example

The following shows how to set the query interval to 100 seconds:

ip igmp snooping query-max-response-time

Use this command to set the snooping report delay. Add the "no" form before the command to restore

the default.

• Syntax

- seconds: The report delay informed by IGMP queries. (Range: 5–30)

• Default Setting

10 Seconds

• Command Mode


• Command Details

- The switch must be using IGMPv2 for this command to be enabled.

- The command sets the time the switch waits after receiving an IGMP report (for an IP multicast

address) on a port before it sends an IGMP Query to that port and removes the entry from its list.

- The command sets the time the switch waits from sending a query to receiving a response from the

multicast client. When the client sends no response, even after the querier device has issued the

number of queries specified by the "ip igmp snooping query-count" command, the querier device

takes action after the countdown timer shows the elapsed time specified by this command. If the

client sent no response by the time the timer has counted down, the client is removed from the

multicast group.

• Example

The following shows how to set the maximum response time to 20 seconds:

ip igmp snooping query-interval seconds

no ip igmp snooping query-interval

Console(config)#ip igmp snooping query-interval 100

4.3.16 Broadcast Storm Control Commands

You can protect the network from broadcast storms by setting a threshold for broadcast traffic for each

port. Any broadcast packets exceeding the specified threshold will be discarded (broadcast storm control

is disabled by default).

broadcast

Use this command to configure broadcast storm control. Add the "no" form before the command to

disable broadcast storm control.

• Syntax

- rate: Threshold level for broadcast rate (broadcast packets per second) (Threshold level: 16, 64,

128, 256)

• Default Setting

Disabled

• Command Mode


• Command Details

- The specified thresholds will be applied to the entire switch.

- "Broadcast Storm Control" does not affect IP multicast traffic.

- This switch has thresholds, such as for buffer capacity that is consumed by broadcast packets. If

broadcast traffic exceeds the specified threshold for buffer space capacity, the switch will drop the

excess broadcast traffic.

5.1 Using SNMP

Simple Network Management Protocol (SNMP) is a communication protocol

designed to control network elements such as various network devices. Using SNMP,

switches, routers, and host computers are controlled. Usually, SNMP is used not only

for configuring these devices to work correctly on the network, but also for monitoring

the devices to evaluate performance, and detect errors that may occur.

To access the switch from the network management station by using SNMP, carry out the following

procedures.

1 Install the SNMP management application in the host computer.

2 Confirm that the management station and the switch are configured to the

same IP domain.

"3.2.3 Setting the IP Address" (pg.38)

3 Configure the community name and access rights to perform network

management access by using SNMP.

"3.3.1 Setting Community Access Strings" (pg.41)

4 To receive trap messages from the switch, specify the trap manager's IP

address, related community name, and the trap types that the switch creates.

"3.3.2 Specifying Trap Managers" (pg.42)

The SNMP management station can configure and monitor the network devices by setting or reading the

device variables specified in MIB (Management Information Base). For details about main MIB groups

supported by the switch, refer to "5.2 Supported MIB" (pg.195).

To monitor the device status or change system parameters on the switch from the network management

system, you need to access appropriate MIB variables using the SNMP management application. Refer

to "5.3 Accessing the MIB Objects" (pg.196).

5.4 SNMP Trap

SNMP trap supports the following items.

5.4.1 Address Accumulation Trap

This switch issues an SNMP trap when the number of entries stored in an address table exceeds 2048.

The SNMP management tool, which was specified in advance, can receive the trap.

Since this SNMP trap has hysteresis mechanism, a subtle change of the counter value does not cause trap

error. This trap is issued when the counter value goes through the threshold zone from 1536 to 2048. For

example, as shown in the following figure, the address accumulation trap is issued at point A, but is not

issued at point B.

8.2 Points to Note

The following are the points to note when using the Switch Blade.

The number of MAC addresses to be learned

When the Switch Blade has learned more than 2000 MAC addresses, it may take a long time to display

the MAC addresses on a Web screen, or a ping received while processing the display of received MAC

addresses may time out. Therefore, configure the network so that the number of MAC addresses to be

learned will not exceed 2000 per Switch Blade. Note that the number of MAC addresses that has already

been learned can be checked via the Web interface of each Switch Blade.

About unnecessary pause frames while executing flow control

If "Flowcontrol" is set to "Enable" in the Switch Blade, an unnecessary pause frame may be sent when a

broadcast frame is received.

In this case, network performance may decrease a little. Therefore, set the "Flowcontrol" to "Disable"

(default setting) for a network that may transmit a large amount of data.

There is no problem for a normal network if "Flowcontrol" is set to "Enable", because it uses broadcast

only for control.

About connecting with external switching hub, etc.

When the Switch Blade is connected to Fujitsu switching hub SH1300T, SH1300F or FMV-

DESKPOWER CE series (2002 summer model), the transmission rate of 10Mbps cannot be used.

Connect them at the fixed transmission speed of 100Mbps.

Notes on configuring VLAN

• Do not configure or change VLAN for the Switch Blade while operating the network.

Doing so may cause problems for network operation, because all ports are disabled when configuring

or changing VLAN.

• When using the VLAN function of the Switch Blade to split the network into 2 or more, a server

blade cannot be installed to server blade slot 5 in the chassis. The maximum number of server blades

that can be installed is 9.

• The Spanning Tree function of this switch works regardless of the VLAN configuration. Therefore, if

network groups are configured, all ports except for one port are disabled, even if they belong to

different VLANs, so the VLANs to which the disabled ports belong may not be able to communicate.

When using VLAN and configuring network groups, disable Spanning Tree.

Be sure to observe this restriction, especially for the network where the devices are monitored with

ping.

Settings for external ports (11–13) when disabling the auto-negotiation function

When disabling the auto-negotiation function, the Auto-MDI function is also disabled. The following

table shows the relation between the settings of external ports 11–13 and the cables used in static mode,

when disabling the auto-negotiation function. Use the correct cables.
