MAC address table - static entry

When configuring a switch, it is possible to assign a static MAC address within the MAC address table. This can be done using the following command:

SW1(config)#mac address-table static 001d.a18b.36d0 vlan 1 interface fastEthernet 0/1

The above command will place a static entry in the MAC address table like so:

SW1#show mac address-table static | include Fa0/1 1 001d.a18b.36d0 STATIC Fa0/1

Some platforms allow a static MAC entry to correspond with multiple interfaces. This should be done with caution as it may cause MAC address flapping.
