Protocol Based VLAN Group Configuration
Protocol-based VLAN can be used 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. Enter a number used to identify the group created by the user. Group IDs should be
assigned when a group is created by the user. The Group IDs range is 1–128.
2. Assign a name to a new group in the Group Name field. You may enter up to 16 characters.
3. Populate the Protocol(s) field - Protocol-list can be any valid comma(,) separated string with
standard “arp”, “ip”, “ipx” keywords, hexadecimal, or decimal values in the range of
0x0600(1536) to 0xFFFF(65535).
