Chapter 5: MAC Address Table
114
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. The switch deletes a MAC address from the
table when no packets are sent to or received from the end node of the
address for the period of time specified by the aging time. This prevents
the table from filling with addresses of nodes that are no longer active.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 Main Menu, type
4
to select MAC Address Tables.
The MAC Address Tables menu is shown in Figure 30 on page 106.
2. From the MAC Address Tables menu, type
1
to select MAC Address
Aging Time.
The following prompt is displayed:
Enter MAC address aging time -> [8 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 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.
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.
