Command Usage
Make sure that no dot1q-tunnel port is configured before exiting QinQ mode
(see section 7.17.26 on page 884). If there are any dot1q-tunnel ports set
on the ECN330-switch, the no system mode command will fail. If any
L2MPLS VLANs or L2MPLS uplink ports are configured, the system mode
qinq and no system mode commands will also fail.
Example
