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 node
addresses that are inactive.
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.
The Configuration System Page is displayed with the General Tab
selected by default, as shown in Figure 192 on page 584.
2. In the Configuration section, enter a new value, in seconds, in the
MAC Address Aging Time field.
The range for this field is from 8 to 512 seconds.
3. Click Apply.
Your changes are immediately activated on the switch.
4. Click Save Changes.
The changes you made are saved on the switch.
