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 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nodes that are no longer active.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 default setting for the aging time is 300 seconds (5 minutes).
To adjust the aging time, perform the following procedure:
1. From the Main Menu, type 5 to select System Config Menu.
2. From the System Config Menu, type 1 to select MAC Aging Time.
The following prompt is displayed:
Enter your new value -> [1 to 1048575]
3. Enter a new value in seconds.
The value should be an increment of 5 seconds, for example 410,
415, or 420. A value that is not an increment of 5 is rounded down
to the next increment of 5. For example, the value 524 is rounded
down to 520.
The new value is immediately activated on the switch.
