Implementation Of Protocol-Based Vlan - H3C S5100-SI Operation Manual

Implementation of Protocol-Based VLAN

S5100-SI/EI series Ethernet switches assign the packet to the specific VLAN by matching the packet
with the protocol template.
The protocol template is the standard to determine the protocol to which a packet belongs. Protocol
templates include standard templates and user-defined templates:
The standard template adopts the RFC-defined packet encapsulation formats and values of some
specific fields as the matching criteria.
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.
