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, Decent 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.
Protocol to Group
Information
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.
1. Select Configuration > VCL > Protocol-based VLAN > Protocol to Group
2. By Default there will be nothing in the protocol to Group Mapping Table. To create a
mapping Select Add New Entry
3. Choose the Frame Type from the drop down menu and then assign the Etype Value by
entering this into the text box.
4. Add the Group name then select Apply
