Configuration Archive Auto-Revert

Configuration archive auto-revert provides the capability to revert or roll back to a previous configuration if the changed running configuration is not saved to the non-volatile memory within a predefined time. This prevents the system from entering an unknown state by reminding the system administrator that the running configuration has changed and these configurations have not been saved. If the write memory command is not used after the reminder is issued, the system can reload automatically using the golden archive that has been previously configured.

When an ICX system runs from non-volatile configurations without any changes, it is assumed that the system is running under a supervised state or is in a stable state. The time interval between changing any running configuration and saving it into the non-volatile memory is known as an un-supervised or unstable state. Changes to the configuration are saved using the write memory command and the system transits from an unsupervised state to a supervised state. Configuration archive auto-revert steps in when the system runs over a period of time in un-supervised state so that the last snapshot of the system is saved before the system is reloaded.

When an auto-revert time expiry occurs, an informational message is displayed in any newly connected session through the console, Telnet, or SSH.
