Protocol Based VLANs
Path: Network > VLAN > Advanced VLAN > Protocol Based VLAN
In a protocol‐based VLAN, trac is bridged through specied ports based on the protocol associated with the
VLAN. User‐dened packet lters 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 dene ltering criteria for untagged packets. By default, if you do not
congure any port‐based (IEEE 802.1Q) or protocol‐based VLANs, untagged packets are assigned to VLAN 1. You
can override this behavior by dening 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 specic 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 specically
assigned to the port using the Port VLAN Conguration screen. Use the Protocol‐based VLAN Conguration
page to congure which protocols go to which VLANs, and then enable certain ports to use these settings.
You dene 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 denitions, and can include multiple ports.
1. Go to Network > VLAN > Advanced VLAN > Protocol Based VLAN tab.
