3-10.7 Protocol -based VLAN
This section describe Protocol -based VLAN, The Switch support Protocol include Ethernet
LLC SNAP Protocol,
LLC
The Logical Link Control (LLC) data communication protocol layer is the upper sub-layer of
the Data Link Layer (which is itself layer 2, just above the Physical Layer) in the seven-
layer OSI reference model. It provides multiplexing mechanisms that make it possible for
several network protocols (IP, IPX, Decnet and Appletalk) to coexist within a multipoint
network and to be transported over the same network media, and can also provide flow
control and automatic repeat request (ARQ) error management mechanisms.
SNAP
The Subnetwork Access Protocol (SNAP) is a mechanism for multiplexing, on networks using
IEEE 802.2 LLC, more protocols than can be distinguished by the 8-bit 802.2 Service Access
Point (SAP) fields. SNAP supports identifying protocols by Ethernet type field values; it also
supports vendor-private protocol identifier spaces. It is used with IEEE 802.3, IEEE
802.4, IEEE 802.5, IEEE 802.11 and other IEEE 802 physical network layers, as well as with
non-IEEE 802 physical network layers such as FDDI that use 802.2 LLC.
3-10.7.1 Protocol to Group
This page allows you to add new protocols to Group Name (unique for each Group) mapping
entries as well as allow you to see and delete already mapped entries for the selected stack
switch unit switch.
Web Interface
To configure Protocol -based VLAN configuration in the web interface:
1. Click Protocol -based VLAN configuration add new entry.
2. Specify the Ethernet LLC SNAP Protocol and Group Name.
3. Click Apply.
