MAC-based VLAN
The MAC-based VLAN feature assigns incoming untagged packets to a VLAN and classifies the
traffic based on the source MAC address of the packet. When untagged packets arrive at the switch,
the source MAC address of the packet is looked up in a MAC to VLAN mapping table. If an entry is
found, the corresponding VLAN ID is assigned to the packet. The assigned VLAN ID is verified
against the VLAN table. If the VLAN is valid, ingress processing on the packet continues; otherwise,
the packet is dropped.
This feature allows users to change ports without having to reconfigure the VLAN, which allows
better mobility. You can assign priority to the MAC-based VLAN and define a MAC to VLAN mapping
table by entering a specified source MAC address in the MAC-based VLAN setup screen. You can
also delete a MAC-based VLAN entry in the same screen.
Click MAC-based VLAN in the VLAN Configuration window to see the following screen.
