Configuring basic QinQ
This section describes how to configure basic QinQ.
Enabling basic QinQ
Enable QinQ on the customer-side port.
A basic QinQ-enabled port tags an incoming packet with its PVID tag.
To enable basic QinQ:

Configuring VLAN transparent transmission
When basic QinQ is enabled on a port, all packets passing through the port are tagged with the port's
PVID tag. You can exclude a VLAN (for example, the management VLAN) from the QinQ tagging action.
This VLAN is called a "transparent VLAN."
To ensure successful transmissions for a transparent VLAN, follow these configuration guidelines:
• Set the link type of the port to trunk or hybrid, and assign the port to the transparent VLAN.
• Make sure all ports on the traffic path permit the transparent VLAN to pass through.
• Do not configure VLAN mapping for the transparent VLAN on the port. For more information about
VLAN mapping, see "Configuring VLAN mapping."
