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that are no longer active.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 configure the aging time, perform the following procedure:
1. From the Home page, select Configuration.
The System page is displayed with the General tab selected by default,
as shown in Figure 5 on page 38.
2. In the Configuration section, for the MAC Address Aging Time, 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.
3. Click Apply.
4. From the Configuration menu, select the Save Config option to
permanently save your changes. (This option is not displayed if there
are no changes to save.)
