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 1, Level 2,
Level 3, Level 4, Level 5, Level 6, Level 7, or Default.
MAC Address Aging Enter the desired MAC address
age-out time in this field (10 to 9999 seconds).
