18.2.4 Dot1q-tunnel Troubleshooting
 Enabling dot1q-tunnel on Trunk port will make the tag of the data packet unpredictable
which is not required in the application. So it is not recommended to enable dot1q-
tunnel on Trunk port.
 Enabled with STP/MSTP is not supported.
 Enabled with PVLAN is not supported.
18.3 Selective QinQ Configuration
18.3.1 Introduction to Selective QinQ
Selective QinQ is an enhanced application for dot1q tunnel function. It is able to tag packets
(they are received by the same port) with different outer VLAN tags based on different inner
VLAN tags according to user’s requirement, so it is able to implement that packets of different
types are assigned to different VLAN by selecting different transmission path.
