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nodes that are no longer active.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 the System Menu.
2. From the System Menu, type 1 to select Configure System.
The Configure System Menu is shown in Figure 9 on page 52.
3. From the Configure System menu, type 1 to select Configure System
Software.
The Configure System Software menu is shown in Figure 10 on
page 53.
4. From the Configure System Software menu, type 3 to select MAC
Address Aging Time.
The following prompt is displayed:
Enter MAC address aging timer -> [8 to 512]
5. Enter a new value in seconds.
The new value is immediately activated on the switch.
6. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
