Changing the Aging Time
The switch uses the aging time to delete inactive dynamic MAC
addresses from the MAC address table. When the switch detects that no
packets have been 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nodes that are no longer active.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 default setting for the aging time is 300 seconds (5 minutes).
To adjust the aging time, perform the following procedure:
Note

MAC Address by Port, Display MAC Address by MAC, and Display
