perform the following procedure:
1. From the Omega Main Menu, select MAC Address Table.
2. Select Clear dynamic MAC table.

Changing the
Aging Time of the
MAC Address
Table
If a switch detects a packet with a new source MAC address, the switch
stores the MAC address in its address table. This means the switch has
learned about the device that sent packets to the switch. The MAC
address table is updated as new MAC addresses are detected. If a MAC
address listed in the address table does not appear on any port after a
specified period of time, the switch deletes that address from the table.
The default aging time is 300 seconds.
To specify a new aging time for the MAC address table, perform the
following procedure:
1. From the Omega Main Menu, select System Configuration.
The System Configuration menu in Figure 8 on page 43 is displayed.
2. Enter a new value (in seconds) in the Default Aging Time entry field.
The default is 300 seconds. The maximum value is 999 seconds.
Note
Entering a value of 0 (zero) deactivates the MAC aging time
parameter. MAC addresses continue to be added to the table until
the table is full. Once the table is full, any frame with a new MAC
address will be flooded to all appropriate ports.
3. Return to the Main Menu.
