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.
Configuring a Protocol-Based VLAN
Follow these steps to configure a protocol-based VLAN:
To do… Use the command… Remarks
Enter system view system-view —
Enter VLAN view
vlan vlan-id
Required
If the specified VLAN does
not exist, this command
creates the VLAN first.
Create a protocol template for the
VLAN

ipv6 | ipx { ethernetii | llc |
raw | snap } | mode
{ ethernetii etype etype-id |
llc { dsap dsap-id [ ssap

aggregate interface and all
its member ports.
Configure the port link type as
hybrid
port link-type hybrid Required
Configure current hybrid port(s) to
permit the packets of the specified
protocol-based VLANs to pass
through
port hybrid vlan vlan-id-list
{ tagged | untagged }
Required
By default, all hybrid ports
permit packets of VLAN 1 to
pass through only.
Associate the hybrid port(s) with
the specified protocol-based
VLAN port hybrid protocol-vlan
