MAC ADDRESS-TABLE AGEING-TIME

Syntax

mac address-table ageing-time

time

Parameter

time

Specifies the aging timer in seconds for the MAC address table.
The range is 0 to 1,048,575 seconds. The default is 300 seconds
(5 minutes).

Mode

Global Configuration mode

Description

Use this command to set the aging timer. The aging timer is used by the
switch to delete inactive dynamic entries of MAC addresses from the MAC
address table. By setting the aging timer, you prevent the table from
becoming full of inactive addresses. An address is considered inactive if
no frames are sent to or received from the MAC addresses for the duration
of the timer.

Setting the aging timer to 0 disables the timer. No dynamic MAC
addresses are aged out and the table stops learning new addresses after
reaching its maximum capacity.

To restore the default setting of 300 seconds, use the NO MAC
ADDRESS-TABLE AGEING-TIME command.

Confirmation Command

“SHOW MAC ADDRESS-TABLE” on page 394.

Examples

This example sets the aging timer to 500 seconds:

awplus> enable
awplus# configure terminal
awplus(config)# mac address-table ageing-time 500
