Rescue Configuration
A rescue configuration is the known working configuration. If the active configuration is corrupted, the device automatically loads the rescue configuration file as the active configuration.
Creating and Returning to a Rescue Configuration
A rescue configuration allows you to define a known working configuration or a configuration
with a known state for recovery, if necessary. This alleviates the
necessity of having to remember the rollback number with the rollback command. The rescue configuration rolls back the device
to a known configuration, or can serve as a last resort if your device
configuration and the backup configuration files become damaged beyond
repair.
To save the most recently
committed configuration as the rescue configuration so that you can
return to it at any time, issue the request system configuration
rescue save command:
user@host> request system configuration rescue save
To return to the rescue configuration, use the rollback rescue configuration mode command. To commit the rescue
configuration, thereby activating it, use the commit command.
[edit]
user@host# rollback rescue
load complete
If the rescue configuration does not exist,
or if the rescue configuration is not a complete, viable configuration,
then the rollback command fails, an error message appears,
and the current configuration remains active.
To delete an existing
rescue configuration, issue the request system configuration
rescue delete command:
user@host> request system configuration rescue delete
user@host>
