A static address has these characteristics:

It is manually entered in the address table and must be manually removed.

It can be a unicast or multicast address.

It does not age and is retained when the switch restarts.

You can add and remove static addresses and define the forwarding behavior for them. The forwarding 
behavior defines how a port that receives a packet forwards it to another port for transmission. Because 
all ports are associated with at least one VLAN, the switch acquires the VLAN ID for the address from 
the ports that you specify. You can specify a different list of destination ports for each source port.

A packet with a static address that arrives on a VLAN where it has not been statically entered is flooded 
to all ports and not learned.

You add a static address to the address table by specifying the destination MAC unicast address and the 
VLAN from which it is received. Packets received with this destination address are forwarded to the 
interface specified with the interface-id option. 

When you configure a static MAC address in a private-VLAN primary or secondary VLAN, you should 
also configure the same static MAC address in all associated VLANs. Static MAC addresses configured 
in a private-VLAN primary or secondary VLAN are not replicated in the associated VLAN. For more 
information about private VLANs, see 

Beginning in privileged EXEC mode, follow these steps to add a static address:

To remove static entries from the address table, use the no mac address-table static mac-addr vlan 
vlan-id [interface interface-id] global configuration command.

Enter global configuration mode.

mac address-table static mac-addr 
vlan vlan-id interface interface-id 

Add a static address to the MAC address table.

For mac-addr, specify the destination MAC unicast address to add to 
the address table. Packets with this destination address received in the 
specified VLAN are forwarded to the specified interface.

For vlan-id, specify the VLAN for which the packet with the 
specified MAC address is received. Valid VLAN IDs are 1 to 4094.

For interface-id, specify the interface to which the received packet is 
forwarded. Valid interfaces include physical ports or port channels. 
For static multicast addresses, you can enter multiple interface IDs. 
For static unicast addresses, you can enter only one interface at a 
time, but you can enter the command multiple times with the same 
MAC address and VLAN ID. 

Return to privileged EXEC mode.

Verify your entries.

(Optional) Save your entries in the configuration file.
