MAC ADDRESS-TABLE AGEING-TIME
Syntax
mac address-table ageing-time
value
|
none
Parameter
ageing-time
Specifies the aging timer in seconds for the MAC address table.
The range is 10 to 1000000 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 MAC addresses from the MAC address
table, to prevent the table from becoming full of inactive addresses. An
address is considered inactive if no packets are sent to or received from
the corresponding node for the duration of the timer.
Setting the aging timer to none disables the timer. No dynamic MAC
addresses are aged out, and the table stops learning new addresses after
reaching its maximum capacity.
To return the aging timer to its default value, use the NO form of this
command.
Confirmation Command
“SHOW MAC ADDRESS-TABLE” on page 406.
Examples
This example sets the aging timer to 500 seconds:
awplus> enable
awplus# configure terminal
awplus(config)# mac address-table ageing-time 500
