9.3.5 Dot1q-tunnel Troubleshooting

Enabling dot1q-tunnel on Trunk port，that is usually not required in the application,
will make the tag of the data packet unpredictable. So it is not recommended to
enable dot1q-tunnel on Trunk port except the VLAN-translation is in operation.
Configuring in port-channel is not supported.
Enabled with STP/MSTP is not supported.
Enabled with PVLAN is not supported.
Enabled with DOT1X is not supported.
