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 add a protocol based VLAN group:

1.Select Switching > VLAN > Advanced > Protocol Based VLAN Group Configuration.

2.Under Group ID, specify a unique number used to identify the group.

3.Under Group Name, specify a name to identify the group. You can enter up to 16 characters.

4.Under Protocol, specify the protocol or protocols to use as the match criteria to determine whether a particular packet belongs to the protocol-based VLAN.

The protocols you specify are checked against the two-byte EtherType field of ingress Ethernet frames on the PVBLAN Group Interfaces. When adding a protocol, you can specify the EtherType hex value or (for IP, ARP, and IPX) the protocol keyword.

5.Under VLAN ID, specify the VLAN ID to associate with the protocol-based VLAN.

All the ports in the group will assign this VLAN ID to untagged packets received for the protocols you included in this group.

The Ports field displays all the member ports which belong to the group.

6.Click Add.
