Controller versions above 0.9.2 support temporarily falling back to DHCP by doing the following 10 times:
- Unplugging the network cable
- Waiting 1 second
- Replugging the network cable
The DHCP on the controller will be temporarily enabled and any pending cloud network settings will be written out (finishes with a reboot). If there are no cloud network settings, the next time the controller reboots it will return to its original network configuration.
