Protocol Based VLAN Group Configuration

You can use a protocol based VLAN to define filtering criteria for untagged packets. By

default, if you do not configure any port- (IEEE 802.1Q) or protocol based VLANs, untagged

packets will be assigned to VLAN 1. You can override this behavior by defining either

port-based VLANs or protocol based VLANs, or both. Tagged packets are always handled

according to the IEEE 802.1Q standard, and are not included in protocol based VLANs.

If you assign a port to a protocol based VLAN for a specific protocol, untagged frames

received on that port for that protocol will be assigned the protocol based VLAN ID. Untagged

frames received on the port for other protocols will be assigned the Port VLAN ID - either the

default PVID (1) or a PVID you have specifically assigned to the port using the Port VLAN

Configuration screen.

You define a protocol based VLAN by creating a group. Each group has a one-to-one

relationship with a VLAN ID, can include one to three protocol definitions, and can include

multiple ports. When you create a group you will choose a name and a Group ID will be

assigned automatically.

To configure a protocol-based VLAN group:

1. Use Group ID to specify a unique ID for the group.

2. Use Group Name

to assign a name to a new group. You may enter up to 16 characters.

3. Use Protocol(s) to specify the protocols you want to be associated with the group. The

protocol options are as follows:

• IP - IP is a network layer protocol that provides a connectionless service for the

delivery of data.

• ARP - Address Resolution Protocol (ARP) is a low-level protocol that dynamically

maps network layer addresses to physical medium access control (MAC) addresses

• IPX - The Internetwork Packet Exchange (IPX) is a connectionless datagram

Network-layer protocol that forwards data over a network.

• User-specified hexadecimal or decimal value in the range of 0x0600 (1536) to

0xFFFF (65535).
