Changing QinQ modes
Changing QinQ modes (or disabling QinQ operations) will result in the current configuration being erased. See the following Caution for details.
CAUTION:
Configuring the switch to operate in a different bridge mode requires a reboot to take effect. Upon reboot, all configuration information for the prior QinQ mode is lost. Any configurations created under the existing QinQ mode is erased, and the device boots up with a default configuration for the new QinQ mode.
For information on the effect of the different QinQ modes on switch protocols and operations, see the table Impacts of QinQ configurations on other switch features.
