Adding Static Addresses

Beginning in privileged EXEC mode, follow these steps to remove a secure
address:
Purpose
Enter global configuration mode.
Enter the secure MAC address, its associated port, and the
VLAN ID to be removed.
Return to privileged EXEC mode.
You can remove all secure addresses by using the clear mac-address-table
secure command in privileged EXEC mode.
A static address has the following 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 determine 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 select on the
forwarding map.
A static address in one VLAN must be a static address in other VLANs. 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.
Static addresses are entered in the address table with an in-port-list, an
out-port-list, and a VLAN ID, if needed. Packets received from the in-port list are
forwarded to ports listed in the out-port-list.
