Chapter 19: MAC Address Table

Setting the Aging Timer

The aging timer defines the length of time that inactive dynamic MAC
addresses remain in the table before they are deleted by the switch. The
switch deletes inactive addresses to insure that the table contains only
active and current addresses.
The aging timer does not apply to static addresses because static
addresses are not deleted by the switch, even when the network devices
are inactive.
To set the aging timer, use the MAC ADDRESS-TABLE AGEING-TIME
command in the Global Configuration mode. Here is the format of the
command:
value none
mac address-table ageing-time |
The aging-time is expressed in seconds and has a range of 10 to 1000000
seconds. The default is 300 seconds (5 minutes). The value none disables
the aging timer so that inactive MAC addresses are never deleted from the
table.
To view the current setting for the MAC address aging timer, refer to
"Displaying the MAC Address Table" on page 377.
This example sets the aging timer to 800 seconds:
awplus> enable
awplus# configure terminal
awplus(config)# mac address-table ageing-time 800
