ANAGING ROTOCOL ASED S
In a protocol-based VLAN, traffic is bridged through specified ports based on the protocol associated with the VLAN. User-
defined packet filters determine whether a particular packet belongs to a particular VLAN. Protocol-based VLANs are most
often used in situations where network segments contain hosts running multiple protocols.
You can use a protocol-based VLAN to define filtering criteria for untagged packets. By default, if you do not configure any
port-based (IEEE 802.1Q) or protocol-based VLANs, untagged packets are assigned to VLAN 1. You can override this
behavior by defining either port-based VLANs, 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 (PVID), which is either the default PVID (1) or a PVID you have specifically assigned to the port using the Port
VLAN Configuration screen.

ONFIGURATION
Use the Protocol-based VLAN Configuration page to configure which protocols go to which VLANs, and then enable certain
ports to use these settings.
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 or more protocol definitions, and can include multiple ports.
