JunOS Rescue Configuration

Juniper Rescue Configuration

In addition to snapshots, Juniper devices can generate a rescue configuration. This is a known good configuration that’s saved in case there is a disaster.

If there’s a problem with the ‘live’ configuration (such as a corruption), the rescue configuration can automatically be loaded. This also provides a known-good configuration that you may wish to roll back to.


To create the rescue configuration:

user@Switch01> request system configuration rescue save


Use show system configuration rescue to see the entire rescue configuration.

To rollback to the rescue configuration:

user@Switch01# rollback rescue
load complete
user@Switch01# commit


Some EX-Series switches come with an LCD panel on the front. If you have lost access to the switch, you can use the LCD panel to rollback to the rescue configuration.
