Book Title
You can remove all secure addresses by using the
clear mac-address-table secure
command in
privileged EXEC mode.
Verifying Secure Addresses
Use the
show mac
-
address
-
table secure
command to verify configuration:
Router#
show mac-address-table secure
Configuring Static Addresses
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.
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.
Follow these steps to add a static address.
