1.3.5 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.
