Configuring MAC Based VLANs
– 496 –
mac-vlan This command configures MAC address-to-VLAN mapping. Use the no form to
remove an assignment.
Syntax
mac-vlan mac-address mac-address [mask mask-address] vlan vlan-id
[priority priority]
no mac-vlan mac-address {mac-address [mask mask-address] | all}
mac-address – The source MAC address to be matched. Configured 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)
Default Setting
None
Command Mode
Global Configuration
Command Usage
◆ The MAC-to-VLAN mapping applies to all ports on the switch.
◆ Source MAC addresses can be mapped to only one VLAN ID.
◆ Configured MAC addresses cannot be 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)#
