Juniper SRX / Junos rescue configuration is not set

Juniper devices configuration is saved in files named "juniper.conf.gz" and historical configuratio is saved as "juniper.conf.X.gz" where X is the number of backup configurations saved (max-configuration-rollbacks). Another important configuration role is the rescue configuration which is contained in /config/rescue.conf.gz.

The SRX devices also have a feature called "Reset configuration" which is triggred by the "Reset config" button on front panel. If pressed and released, this button loads the a rescue configuration, a configuration snapshot chosen by the administrator at a specific point in time and is a way of remotely restore a configuration if remote access has been terminated by a configuration or protocol change. The only requirement is physical access to the box to remote personel (trained or untrained).

Saving rescue configuration in Junos

The "request" Junos operational command is used to operate on the rescue configuration:

Code:

admin@R1> request system configuration rescue save 

admin@R1> 

Load Junos rescue configuration

This requires configuration mode.

Code:

Another method of loading the rescue configuration in Junos is pressing shortly the "Reset Config" button in front panel.!!!!! Pressing and holding the "Reset config" button for more than 15 seconds will delete all configuration on the device (backup and rescue configuration) and it will load factory defaults. !!!!!

View the rescue configuration in Junos

Code:

admin@R1> show system configuration rescue
