Create A Mac-Based Vlan - NETGEAR ProSafe GSM5212P Software Administration Manual

Create a MAC-Based VLAN

The MAC-based VLAN feature allows incoming untagged packets to be assigned to a VLAN
and thus classify traffic based on the source MAC address of the packet.
You define a MAC to VLAN mapping by configuring an entry in the MAC to VLAN table. An
entry is specified using a source MAC address and the appropriate VLAN ID. The MAC to
VLAN configurations are shared across all ports of the device (i.e., there is a system-wide
table that has MAC address to VLAN ID mappings).
When untagged or priority tagged packets arrive at the switch and entries exist in the MAC to
VLAN table, the source MAC address of the packet is looked up. If an entry is found, the
corresponding VLAN ID is assigned to the packet. If the packet is already priority tagged it will
maintain this value; otherwise, the priority will be set to 0 (zero). 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 implies that you can configure a MAC
address mapping to a VLAN that has not been created on the system.
