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 that you can roll back to at any time. This alleviates the necessity of having to remember the rollback number with the rollback command. You use the rescue configuration when you need to roll back to a known configuration or as a last resort if your router or switch 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:
To return to the rescue configuration, use the rollback rescue configuration mode command:
 | Note: If the rescue configuration does not exist, or if the rescue configuration is not a complete, viable configuration, the rollback command fails, an error message appears, and the current configuration remains active. |
To activate the rescue configuration that you have loaded, use the commit command:
To delete an existing rescue configuration, issue the request system configuration rescue delete command:
For more information about the request system configuration rescue delete and request system configuration rescue save commands, see the Junos OS Operational Mode Commands.
