VLAN for each interface that will participate in the group.
PATH
Advanced Configuration, VCL, Protocol-based VLANs, Group to VLAN
COMMAND USAGE
◆ When creating a protocol-based VLAN, only assign interfaces using this
configuration screen. If you assign interfaces using any of the other
VLAN menus such as the VLAN Static table (page 173), 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.
■
If the frame is untagged but the protocol type does not match, the
frame is forwarded to the default VLAN for this interface.
PARAMETERS

◆ Group Name – The name assigned to the Protocol VLAN Group. This
name must be a unique 16-character long string which consists of a

(Range: 1-4095)
