mac-address

Use the mac-address command to set the MAC layer address.

mac-address ieee-address

Syntax Description

ieee-address

48-bit IEEE MAC address written as a dotted triplet of 4-digit hexadecimal numbers.


Default

No MAC layer address is set.

Command Type

Cisco IOS ATM command.

Command Mode

Interface configuration.

Usage Guidelines

This command is not supported on the Catalyst 4000 and 2948G series switches.

If you have a LECS, LES, or BUS configured on an ATM module, and you replace the supervisor engine module or move the ATM module from one slot to another, you can use the mac-address command to modify the default ATM address network service access points (NSAPs). This way, if you replace the supervisor engine module or move the ATM module from one slot to another, the NSAP is taken from the MAC address instead of the supervisor engine module.

Example

This example shows how to set the MAC layer address, where xx.xxxx is an appropriate second half of the MAC address to use. 

ATM(config-if)#mac-address 5000.5axx.xxxx

meminfo

Use the meminfo command to display information about the main memory, packet memory, and NVRAM. With the -l option, the supported DRAM configurations are displayed.

meminfo [-l]

Syntax Description

-l

(Optional) Keyword to specify long listing—displays DRAM configurations.


Default

This command has no default setting.

Command Type

ROM monitor command.

Command Mode

Normal.

Usage Guideline

The minus sign (-) is required with the -l option.

Example

This example shows how to use the meminfo command: 

rommon 9 > meminfo


Main memory size: 16 MB in 32 bit mode.

Available main memory starts at 0xa000e000, size 16328KB

IO (packet) memory size: 25 percent of main memory.

NVRAM size: 32KB

On a Cisco 3640 router, meminfo -l displays the following tables. The size of the SIMM indicated is its total size. The "-DUAL" attached to the size indicates that the SIMM is a dual-bank SIMM. For example, "8M" indicates that the SIMM is a single bank with a total size of 8 MB. "8M-DUAL" indicates that the SIMM is dual bank with a total size of 8 MB (4 MB on each bank).

Default

This command has no default setting.

Command Type

Cisco IOS ATM command.

Command Mode

Interface configuration.

Usage Guidelines

This command is not supported on the Catalyst 4000 and 2948G series switches.

The mpoa client name command provides an interface to the MPC through which the MPC can set up and receive calls.

When you enter this command on a major interface that is up and operational, the named MPC becomes operational. After the MPC is fully operational, it can register its ATM address.

Example

This example shows how to attach the MPC ip_mpc to an interface: 

ATM (config)#mpoa client config name ip_mpc

mpoa-client-config#int atm 1/0

config-if#mpoa client name ip_mpc

config-if#

name

Use the name command to assign a unique ELAN name to a LES and to configure an ELAN. The no form of this command deletes the specified ELAN name.

name elan-name elan-id id {local-seg-id | new-name | preempt | restricted |         server-atm-address | un-restricted} atm-addr
no name elan_id atm-addr

Syntax Description

elan_name

Name of the ELAN.

elan_id

Keyword to specify the ELAN ID of the ELAN.

id

ELAN ID of the ELAN.

local-seg-id

Keyword to specify the local segment number for this emulated TR LAN.

new-name

Keyword to introduce a new name for this ELAN.

preempt

Keyword to turn on higher priority LES preemption.

restricted

Keyword to close this ELAN to access by name only.

server-atm- address

Keyword to specify the LES-NSAP address for this ELAN.

un-restricted

Keyword to open this ELAN to access by name only.

atm-addr

ATM address of the LANE client.


Default

The default has higher priority LES preemption off.

Command Type

Catalyst 5000, 2926G, and 2926 series ATM module command.

Command Mode

Database configuration.

Usage Guidelines

This command is not supported on the Catalyst 4000 and 2948G series switches.

Use this command when setting up the LECS database on Catalyst 5000, 2926G, and 2926 series switches or when configuring the address of a LES/BUS.

When you enter the name elan-name elan-id id preempt command to turn on higher priority LES preemption, if the primary LANE server (LES) fails, a switchover to a secondary LES occurs. But when a LES that is ranked higher in the priority list becomes active, the active LES is switched to the new LES (with the higher priority).

If you use the default configuration, the second switchover to the new LES does not occur, regardless of the priority. Use the no form of the command to turn off higher priority LES preemption.

The new-name and preempt keywords are supported in Catalyst 5000, 2926G, and 2926 series ATM software release 3.2(8) and later.

Example

This example shows how to configure the LES ATM NSAP address for the default ELAN: 

ATM(lane-config-database)#name default server-atm-address 
47.0091810000000061705b7701.00400BFF0011.00

ping

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

ping [-s] host [packet_size] [packet_count]

Syntax Description

-s

(Optional) Keyword to cause ping to send one datagram per second, printing one line of output for every response received. The ping command returns output only when a response is received.

host

IP address or IP alias of the host.

packet_size

(Optional) Number of bytes in a packet, from 56 to 1472 bytes. The default is 56 bytes; the actual packet size will be 8 bytes larger than the size specified because the switch adds header information.

packet_count

(Optional) Number of packets to send.


Default

This command has no default setting.

Command Type

Switch command.

Command Mode

Normal.

Usage Guidelines

Press Ctrl-C to stop pinging.

Following are sample 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, a "no answer from host" appears in ten seconds.

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

•Network or host unreachable—The switch found no corresponding entry in the route table.

Examples

This example shows how to ping a host with IP alias elvis a single time: 

Console> ping elvis

elvis is alive

Console>

This example shows how to ping a host with IP alias elvis once per second until you press Ctrl-C to stop pinging: 

Console> ping -s elvis

ping elvis: 56 data bytes

64 bytes from elvis: icmp_seq=0. time=11 ms

64 bytes from elvis: icmp_seq=1. time=8 ms

64 bytes from elvis: icmp_seq=2. time=8 ms
