QinQ implementations
HP provides the following QinQ implementations:
• Basic QinQ—Basic QinQ enables a port to tag any incoming frames with its PVID tag, regardless
of whether they have already been tagged. If an incoming frame has been tagged, it becomes a
double-tagged frame. If the frame has not been tagged, it becomes a single-tagged frame.
• Selective QinQ—Selective QinQ is more flexible than basic QinQ. In addition to all functions of
basic QinQ, selective QinQ enables a port to perform the following per-CVLAN actions for
incoming frames:
{ Tags frames from different CVLANs with different SVLAN tags.
{ Marks the SVLAN 802.1p priority based on the existing CVLAN 802.1p priority.
{ Modifies the CVLAN ID.

QinQ configuration task list
When you configure QinQ, follow these guidelines:
• QinQ requires configurations only on the service provider network.
• QinQ configurations made in Ethernet interface view take effect on the current interface only. The
configurations made in Layer 2 aggregate interface view take effect on the current aggregate
interface and all the member ports in the aggregation group. The configurations made in port
group view take effect on all member ports in the current port group.
• Do not configure QinQ on a reflector port. For more information about reflector ports, see Network
Management and Monitoring Configuration Guide.
• On a port with basic QinQ enabled, you must configure the port to allow packets from its PVID to
pass through. On a port with selective QinQ enabled, you must configure the port to allow packets
from the SVLANs to pass through.
