The following fields above can be set:
♦
Lock Address Table
Mostly used for security purposes, when the forwarding table is locked the Switch
will no longer learn the MAC addresses of 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.

Static Forwarding Table
Figure 7-14. Static Forwarding Table window
MAC forwarding allows the Switch to permanently forward outbound traffic to specific destination MAC
addresses over a specified port. To use the MAC forwarding function, enter a MAC address. Whenever the
Switch sees a packet with this destination MAC Address, it will forward it over the module, port, and VLAN
you specify.
