Basic QinQ should be configured on the ports connecting customer networks. 

z 

It is recommended that you do not configure QinQ on an RRPP-enabled port, because RRPP 

packets may be transmitted to the wrong VLANs, causing RRPP to become invalid. If you really 

need to configure QinQ on an RRPP-enabled port, you can configure VLAN mapping on the port 

and configure the RRPP control VLANs as the CVLANs and SVLANs at the same time. In this way, 

the RRPP packets can skip QinQ operations and continue to be transmitted in the control VLANs. 

For detailed information about RRPP control VLANs, refer to the RRPP Configuration in the High 

Availability Volume.  

z 

Do not configure QinQ on a reflector port. For information about reflector ports, refer to Mirroring 

Configuration in the Access Volume. 

 

When basic QinQ is enabled on a port, all packets passing through the port will be tagged with the port’s 

default VLAN tag. However, by configuring the VLAN transparent transmission function on a port, you 

can specify the port not to add its default VLAN tag to packets carrying specific inner VLAN tag(s) when 

they pass through it, so that these packets are transmitted in the service provider network with single 

tags.  

Follow these steps to configure VLAN transparent transmission:
