z
If the packet matches a protocol template, the packet will be tagged with the VLAN tag
corresponding to the protocol template.
z
If the packet matches no protocol template, the packet will be tagged with the default VLAN ID of
the port.
The port processes a tagged packet as it processes tagged packets of a port-based VLAN.
z
If the port permits the VLAN ID of the packet to pass through, the port forwards the packet.
z
If the port does not permit the VLAN ID of the packet to pass through, the port drops the packet.
This feature is mainly used to assign packets of the specific service type to a specific VLAN.
