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 fo
r 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
rela
tionship 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 Sw
itching VLAN Advanced Protocol Based VLAN Group Configuration.
2. Under Group ID, specify a unique number used to identify the group.
3. Under Group Name, spe
cify 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.
