Caution:
z Before enabling selective QinQ on a port, enable basic QinQ on the port first.
Selective QinQ enjoys higher priority than basic QinQ. Therefore, a received frame
will be tagged with an outer VLAN ID based on basic QinQ only after it fails to match
the match criteria defined in the traffic class.
z Selective QinQ is achieved through QoS policies. For detailed information about
QoS policies, refer to the part talking about QoS.

1.5 QinQ Configuration Example
I. Network requirements
z Provider A and Provider B are service provider network access devices.
z Customer A, Customer B, Customer C, and Customer D are customer network
access devices.
z Provider A and Provider B are interconnected through a trunk port, which permits
the frames of VLAN 1000, VLAN 2000, and VLAN 3000 to pass through.
