Purpose
Enters the global configuration mode.
Adds a static address to the MAC address table.
• mac-addr Specifies 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.
• vlan-id Specifies the VLAN for which the packet
with the specified MAC address is received. Valid
VLAN IDs are 1 to 4094.
• interface-id Specifies 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.
Verifies your entries.
(Optional) Saves your entries in the configuration file.
