PVLAN Priority Levels

PVLAN Tagging/Trunk Mode

PVLAN Configuration Guidelines

G8264CS Application Guide for ENOS 8.4
You can assign each PVLAN a priority value of 0‐7, used for Quality of Service
(QoS). PVLAN priority takes precedence over a port's configured priority level. If
no priority level is configured for the PVLAN (priority = 0), each port's priority is
used (if configured).
All member ports of a PVLAN have the same PVLAN priority level.
When PVLAN tagging is enabled, the switch tags frames that match the PVLAN
protocol. For more information about tagging, see "VLAN Tagging/Trunk Mode"
on page 136.
Untagged ports must have PVLAN tagging disabled. Tagged ports can have
PVLAN tagging either enabled or disabled.
PVLAN tagging has higher precedence than port‐based tagging. If a port is
tagging/trunk mode enabled, and the port is a member of a PVLAN, the PVLAN
tags egress frames that match the PVLAN protocol.
Use the tag list command (protocol-vlan <x> tag-pvlan) to define the
complete list of tag‐enabled ports in the PVLAN. Note that all ports not included in
the PVLAN tag list will have PVLAN tagging disabled.
Consider the following guidelines when you configure protocol‐based VLANs:
 Each port can support up to 16 VLAN protocols.
The G8264CS can support up to 16 protocols simultaneously.

 Each PVLAN must have at least one port assigned before it can be activated.
The same port within a port‐based VLAN can belong to multiple PVLANs.

 An untagged port can be a member of multiple PVLANs.
A port cannot be a member of different VLANs with the same protocol

association.
