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 
, the user priority field is the 802.1p priority of the tag. The value of this 3-bit field 
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.
