Implementations of QinQ

HP provides the following QinQ implementations: basic QinQ and selective QinQ.

• Basic QinQ

  Basic QinQ enables a port to tag any incoming frames with its port VLAN ID (PVID) tag, regardless of whether they have been tagged or not. If an incoming frame has been tagged, it becomes a double-tagged frame. If not, it becomes a frame tagged with the PVID tag.

• Selective QinQ

  Selective QinQ is more flexible than basic QinQ. In addition to all the functions of basic QinQ, selective QinQ enables a port to perform the following per-CVLAN actions for incoming frames:

  • Tag frames from different CVLANs with different SVLAN tags.

  • Mark the outer VLAN 802.1p priority based on the existing inner VLAN 802.1p priority.

  • Modify the inner VLAN ID.

  Besides being able to separate the service provider network from the customer networks, selective QinQ provides abundant service features and enables more flexible networking.
