QinQ configuration commands • Throughout this document, customer network VLANs (CVLANs), also called inner VLANs, refer to the VLANs that a customer uses on the private network; and service provider network VLANs (SVLANs), also called outer VLANs, refer to the VLANs that a service provider uses to carry VLAN tagged traffic for customers. • Selective QinQ is achieved through QoS policies. For more information about QoS policy configuration commands, see ACL and QoS Command Reference. nest Syntax nest top-most vlan-id vlan-id View undo nest top-most Traffic behavior view Default level 2: System level Parameters vlan-id vlan-id: Specifies a VLAN tag ID, ranging from 1 to 4094. Description Use nest to add a VLAN nest action to a traffic behavior. If the traffic behavior already contains a VLAN nest action, the new one overwrites the old one. Use undo nest to remove the action. The nest action enables a port to insert an outer VLAN tag in VLAN tagged traffic. If a QoS policy contains a VLAN nest action, apply it only to the incoming traffic of a port, and you must enable basic QinQ on the port first. If this command is configured multiple times for the same traffic behavior, the last configured applies. The nest action cannot be applied to a VLAN or globally. Related commands: qos policy, traffic behavior, and classifier behavior (ACL and QoS Command Reference).
