CONFIGURING MAC BASED VLANS
When using IEEE 802.1Q port-based VLAN classification, all untagged
frames received by a port are classified as belonging to the VLAN whose
VID (PVID) is associated with that port.
When MAC-based VLAN classification is enabled, the source address of
untagged ingress frames are checked against the MAC address-to-VLAN
mapping table. If an entry is found for that address, these frames are
assigned to the VLAN indicated in the entry. If no MAC address is matched,
the untagged frames are classified as belonging to the receiving port’s
VLAN ID (PVID).
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 vlan vlan-id [priority priority]
no mac-vlan mac-address {mac-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.
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)
