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

1. Use Group Name to assign a name to a new group. You may enter up to 16 characters.
2. Use Protocol(s) to select the protocols you want to be associated with the group.
There are
three configurable protocols: IP, IPX, ARP.
• 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.
3. Use VLAN ID to select the VLAN ID. It can be any number in the range of 1 to 4093.
All the
ports in the group will assign this VLAN ID to untagged packets received for the protocols
you included in this group.
4. Click Add to add a new Protocol Based VLAN group to the switch.
5. Click Delete to remove the Protocol Based VLAN group identified by the value in the Group
ID field.
