4.3.2 Protocol-based VLAN
4.3.2.1 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.

Selection Criteria
。 Group ID - You can use this screen to reconfigure or delete an existing protocol-based VLAN, or create a new one.
Use this pulldown menu to select one of the existing PBVLANs, or select 'Create' to add a new one. A Group ID
number will be assigned automatically when you create a new group. You can create up to 128 groups.
Configurable Data
。 Group Name - Use this field to assign a name to a new group. You may enter up to 16 characters.
。 Protocol(s) - Select the protocols you want to be associated with the group. There are three configurable
protocols: IP, IPX, ARP. Hold down the control key to select more than one protocol.
。 IP - IP is a network layer protocol that provides a connectionless service for the delivery of data.
