Chapter 9: MAC Address Table Commands

SET SWITCH AGINGTIMERAGEINGTIMER

Syntax

set switch agingtimerageingtimer=value

Parameter

 

agingtimer

Specifies the aging timer for the MAC address table.

ageingtimer

The value is in seconds. The range is 0 to 1048575

 

seconds. The default is 300 seconds (5 minutes).

 

Entering the value 0 (zero) disables the aging timer.

 

The parameters are equivalent.

Description

 

The switch uses the aging timer to delete inactive dynamic MAC addresses from the MAC address table. When the switch detects that no packets have been sent to or received from a particular MAC address in the table after the period specified by the aging time, the switch deletes the address. This prevents the table from becoming full of addresses of nodes that are no longer active.

The value 0 (zero) disables the aging timer. When disabled, no dynamic addresses are deleted from the table, even addresses that belong to inactive nodes.

Example

The following command sets the aging timer to 120 seconds (2 minutes):

set switch agingtimer=120
