PVLAN Priority Levels

PVLAN Tagging

PVLAN Configuration Guidelines

© Copyright Lenovo 2015
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
on page 122.
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 tag
enabled, and the port is a member of a PVLAN, the PVLAN tags egress frames that
match the PVLAN protocol.
Use the tag-pvlan command (vlan <x> protocol-vlan <x> tag-pvlan <x>)
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 8 VLAN protocols.
The CN4093 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.
