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that are no longer active.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 Home page, select Configuration.
2. Select the Layer 2 menu option.
3. Select the MAC Address tab.
The MAC Address tab is shown in Figure 19 on page 85.
4. In the MAC Address Aging Time section of the tab, enter a new value
in seconds for the MAC Address Aging Time. The range is 0 to
1048575 seconds. The default is 300 seconds (5 minutes). The value
0 (zero) disables the aging timer. When disabled, no dynamic
addresses are deleted from the table, even addresses of inactive
nodes, and the table stops adding new entries after it reaches
maximum capacity.
5. Click Apply.
6. To permanently save the change, select the Save Config menu
option.
