9.8 Vendor ID Based VLAN
The Vendor ID 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 Vendor ID 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. You can assign a
802.1p priority to the vendor ID based VLAN and define a vendor ID to VLAN mapping table by entering
a specified source MAC address and mask in the vendor ID based VLAN setup screen. You can also
delete a vendor ID based VLAN entry in the same screen.
For every vendor ID based VLAN rule you set, you can specify a weight number to define the rule’s
priority level. As rules are processed one after the other, stating a priority order will let you choose which
rule has to be applied first and which second.

OUI mask
Enter the mask for the specified IP phone manufacturer’s OUI MAC address to determine
which bits a packet’s MAC address should match.
Enter “f” for each bit of the specified MAC address that the traffic’s MAC address should
match. Enter “0” for the bits of the matched traffic’s MAC address, which can be of any
hexadecimal characters. For example, if you set the MAC address to 00:13:49:00:00:00
and the mask to ff:ff:ff:00:00:00, a packet with a MAC address of 00:13:49:12:34:56
matches this criteria.
Description
