Configuring the Cisco Gigabit EtherSwitch EHWIC

How to Configure Gigabit EtherSwitch EHWICs

Configuring the Cisco Gigabit EtherSwitch EHWIC

OL-23155-01

DETAILED STEPS

Caution Do not change the aging timer. If you change the aging timer, the EtherSwitch EHWIC could go out of

synchronization.

Verifying the Aging Time

Use the show mac-address-table aging-time command to verify the MAC address table aging timer, as

shown below:

Router#show mac-address-table aging-time

Mac address aging time 320

Configuring Cisco Discovery Protocol

Cisco Discovery Protocol (CDP) is primarily used to obtain protocol addresses of neighboring devices

and discover the platform of those devices. CDP can also be used to display information about the

interfaces your router uses. CDP is media- and protocol-independent, and runs on all

Cisco-manufactured equipment including routers, bridges, access servers, and switches.

For information on how to configure CDP, seeUsing Cisco Discovery Protocol at

Configuring the Switched Port Analyzer

This section describes how to configure a Switched Port Analyzer (SPAN) session for an EtherSwitch

EHWIC.

Note An EtherSwitch EHWIC supports only one SPAN session.

Command Purpose

Step 1

configure terminal

Example:

Router#configure terminal

Enters global configuration mode.

Step 2

mac-address-table aging-time 10-1000000

Example:

Router(config)#mac-address-table aging-time 320

Configures the MAC address aging timer age, in seconds.

Acceptable time range is from 10 to 630.

Step 3

end

Example:

Router(config)#end

Exits configuration mode.
