Inner-To-Outer Tag Priority Mapping; Selective Qinq Configuration; Configuration Task List; Enabling The Selective Qinq Feature For A Port - 3Com WX3000 Series Operation Manual

In this way, you can configure different forwarding policies for data of different type of users, thus
improving the flexibility of network management. On the other hand, network resources are well utilized,
and users of the same type are also isolated by their inner VLAN tags. This helps to improve network
security.

Inner-to-Outer Tag Priority Mapping

As shown in Figure
is in the range 0 to 7. By configuring inner-to-outer tag priority mapping for a VLAN-VPN-enabled port,
you can assign outer tags of different priorities to packets according to their inner tag priorities.
Refer to QoS-QoS profile part for information about priority.
