• group-id - Group identifier of this protocol group. (Range: 1-2147483647)
• vlan-id - VLAN to which matching protocol traffic is forwarded.
(Range: 1-4093)
Default Setting

Command Usage
• When creating a protocol-based VLAN, only assign interfaces via this
command. If you assign interfaces using any of the other VLAN commands
(such as
vlan
on page 34-6), these interfaces will admit traffic of any protocol
type into the associated VLAN.
• When a frame enters a port that has been assigned to a protocol VLAN, it is
processed in the following manner:
- If the frame is tagged, it will be processed according to the standard rules
applied to tagged frames.
- If the frame is untagged and the protocol type matches, the frame is
forwarded to the appropriate VLAN.
