MAC addresses can only be unicast addresses. The MAC address
must be specified in the format xx-xx-xx-xx-xx-xx or xxxxxxxxxxxx.
mask-address - Identifies a range of MAC addresses. The mask can
be specified in the format xx-xx-xx-xx-xx-xx or xxxxxxxxxxxx,
where an equivalent binary value “1” means relevant and “0” means
ignore.
vlan-id – VLAN to which the matching source MAC address traffic is
forwarded. (Range: 1-4094)
priority – The priority assigned to untagged ingress traffic.
(Range: 0-7, where 7 is the highest priority)

COMMAND USAGE
◆ The MAC-to-VLAN mapping applies to all ports on the switch.
◆ The source MAC address can be mapped to only one VLAN ID.
◆ Configured MAC addresses cannot include broadcast or multicast
addresses.
◆ When MAC-based, IP subnet-based, and protocol-based VLANs are
supported concurrently, priority is applied in this sequence, and then
port-based VLANs last.
EXAMPLE
The following example assigns traffic from source MAC address 00-00-00-
11-22-33 to VLAN 10.
Console(config)#mac-vlan mac-address 00-00-00-11-22-33 mask FF-FF-FF-FF-00-00
vlan 10
Console(config)#
