Changing the Aging Time
This procedure changes the aging time of the MAC address table. The
switch uses the aging time to delete inactive dynamic MAC addresses
from the MAC address table. The switch deletes an address from the table
if no packets are sent to or received from the address for the period of time
specified in the timer. This prevents the table from becoming full of
addresses of inactive nodes. The default setting for the aging time is 300
seconds (5 minutes).
To configure the aging time:
5. From the Home page, click the Configuration button.
6. From the Configuration menu, click the Layer 2 button.
7. If the MAC Address tab is not selected, click it. The tab is shown in
Figure 16 on page 64.
8. In the MAC Address Aging Time field, enter a new value in seconds.
The range is 0 to 1048575 seconds. The default is 300 seconds (5
minutes). The value 0 disables the aging timer. If the aging timer is
disabled, inactive dynamic addresses are not deleted from the table
and the switch stops learning new addresses after the table reaches
maximum capacity.
9. Click the Apply button. The new MAC address aging time is
immediately activated on the switch.
10. To save your changes in the master configuration file, click the Save
Config button in the Configuration menu.
