The protocol template is the standard to determine the protocol to which a packet belongs. Protocol
templates include standard templates and user-defined templates:
z The standard template adopts the RFC-defined packet encapsulation formats and values of some
specific fields as the matching criteria.
z The user-defined template adopts the user-defined encapsulation formats and values of some
specific fields as the matching criteria.
After configuring the protocol template, you must add a port to the protocol-based VLAN and associate
this port with the protocol template. This port will add VLAN tags to the packets based on protocol types.
The port in the protocol-based VLAN must be connected to a client. However, a common client cannot
process VLAN-tagged packets. In order that the client can process the packets out of this port, you must
configure the port in the protocol-based VLAN as a hybrid port and configure the port to remove VLAN
tags when forwarding packets of all VLANs.
For the operation of removing VLAN tags when the hybrid port sends packets, refer to the section “Port
Basic Configuration” in this manual.
