1.3.4 Implementation of Protocol-Based VLAN
S3100 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:
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.
