This window allows you to stop or start address learning, use an address look-up mode, and select an age-out time of the
MAC address in the selected address table. Click Apply to let your changes take effect.
The following fields above can be set:
♦ Lock Address Table (Stops learning new address) Mostly used for security purposes, when the forwarding
table is locked the Switch will no longer learn the MAC addresses for new hosts. If your network configuration doesn’t
change, locking the forwarding table helps keep intruders off your network since any packet coming from an unknown
source address will be dropped by the Switch.
♦ Address Look-up Mode Select from: Level 0, Level 1, Level 2, Level 3, Level 4, Level 5, Level 6, or Level 7.
Reboot the Switch to allow the new setting to take effect.
♦ MAC Address Aging Enter the desired MAC address age-out time in this field (10 to 1000000 seconds).
