Zyxel Nebula [Recovery] - Auto Configuration Recovery feature

Nebula's Auto Configuration Recovery is a specialized feature tailored for network switches. Its purpose is to automatically revert the switch to a previously stable configuration if a newly applied configuration causes a disconnection from the Nebula network. This functionality is primarily geared toward preserving network stability and mitigating prolonged downtime resulting from configuration errors.

Simply put, if a new configuration causes the switch to disconnect from Nebula, the Auto Configuration Recovery feature takes action. It promptly reverts the switch to its previous configuration, ensuring it's seamlessly reconnected to Nebula. This rollback process is instantaneous, swiftly restoring the network to a stable state.

Click on the "Change Log" button and the system will redirect you to the Change Log page, which will display all configuration changes made during the last half an hour before locking the device. You can press the unlock button once the configuration error has been corrected.
