Adding Secure Addresses

The secure address table contains secure MAC addresses and their associated ports and VLANs. A
secure address is a manually entered unicast address that is forwarded to only one port per VLAN. If you
enter an address that is already assigned to another port, the switch reassigns the secure address to the
new port.
You can enter a secure port address even when the port does not yet belong to a VLAN. When the port
is later assigned to a VLAN, packets destined for that address are forwarded to the port.
When you change the VLAN ID for a port that is configured with a secure MAC address, you must
Note
reconfigure the secure MAC address to reflect the new VLAN association.
Follow these steps to add a secure address.
