Static MAC addresses can be configured for unicast traffic. This feature improves security and reduces unknown unicast flooding.
(switch (config) #) Configure unicast static MAC address:
mac-address-table static unicast <destination mac address> vlan <vlan identifier(1-4094)> interface ethernet <slot>/<port>
For example:
mac-address-table static 00:11:22:33:44:55 vlan 1 interface ethernet 1/1
