3.10.7 Protocol-based VLAN
This section describe Protocol-based VLAN. The Switch supports protocols including Ethernet, LLC, and SNAP.
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 Sub-network 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
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 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 Apply.
