11.3.7 Managing Protocol-based VLAN
11.3.7.1 Protocol-based VLAN Configuration Page
You can use a protocol-b a sed VLAN to define filterin g crite ria for untagge d packets. By defaul t, 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 receive d 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-ba sed VLAN by creating a group. Each grou p has a one-to-one relationship with a
VLAN ID, can include one to three protocol definitions, and can inclu de multiple ports. When you create a
group you will choose a name and a Group ID will be assigned automatically.
