Configurations made in 
Ethernet port view take 
effect only on the current 
port. 

z 

Configurations made in 
Layer-2 aggregate 
interface view take effect 
on the Layer-2 aggregate 
interface and the member 
ports in the aggregation 
group corresponding to 
the Layer-2 aggregate 
interface.  

z 

Configurations made in 
port group view take 
effect on all ports in the 
port group. 

Enable basic QinQ on the port

The configuration of outer VLAN tag priority is achieved through QoS policies. For more information 

about QoS policies, refer to the part talking about QoS in the QoS Volume. 

 

z 

Provider A and Provider B are service provider network access devices.  

z 

Customer A, Customer B, Customer C, and Customer D are customer network access devices.  

z 

Provider A and Provider B are interconnected through a trunk port, which permits the frames of 

VLAN 1000, VLAN 2000, and VLAN 3000 to pass through.  

z 

Third-party devices are deployed between Provider A and Provider B, with a TPID value of 0x8200.  

The expected result of the configuration is as follows:  

z 

VLAN 10 of Customer A and Customer B can intercommunicate across VLAN 1000 on the public 

network.  

z 

VLAN 20 of Customer A and Customer C can intercommunicate across VLAN 2000 on the public 

network.  

z 

Frames of the VLANs other than VLAN 20 of Customer A can be forwarded to Customer D across 

VLAN 3000 on the public network.
