Chapter 7: MAC Address Table
134 Section I: Basic Operations
Changing the Aging Time
The switch uses the aging time to delete inactive dynamic MAC addresses
from the MAC address table to prevent the table from becoming full of
addresses of inactive nodes. The switch deletes an address from the table
when it detects no packets sent to or received from the address after the
expiration of the time specified by the aging time.
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 4 to select MAC Address Tables.
The MAC Address Tables menu is shown in Figure 29 on page 126.
2. From the MAC Address Tables menu, type 1 to select MAC Address
Aging Time.
The following prompt is displayed:
Enter your new value -> [0 to 1048575]
3. Enter a new value in seconds.
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.
The new value is immediately activated on the switch.
4. After making changes, type R until you return to the Main Menu. Then
type S to select Save Configuration Changes.
