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.
Selective QinQ is achieved through QoS policies. For detailed information about QoS policies, see
QoS Configuration Approaches in the ACL and QoS Configuration Guide.
