2-11.5.3 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.
2-10.5.3.1 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 and add new entry.
2. Specify the Ethernet LLC SNAP Protocol and Group Name.
3. Click Save.
