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.

Name Type a name up to 32 alpha numeric characters for the vendor ID based VLAN entry.
MAC Address Type a MAC address that is bind to the vendor ID-based VLAN entry. This is the source MAC
address of the data packet that is looked up when untagged packets arrive at the Switch.
Mask Type the mask for the specified source 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.
VLAN Type an ID (from 1 to 4094) for the VLAN that is associated with the vendor ID based VLAN
entry.
Priority Select the priority level that the Switch assigns to frames belonging to this VLAN. The higher
the numeric value you assign, the higher the priority for this vendor ID based VLAN entry.
Weight Enter a number between 0 and 255 to specify the rule’s weight. This is to decide the priority
in which the rule is applied. The higher the number, the higher the rule’s priority.
Add Click Add to save the new vendor ID based VLAN entry.
