Configuring Static Addresses

A static address has the following characteristics:
•
•
•
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
