You can create a rescue configuration to be used in the event you make some change to a Juniper Networks SRX router/firewall, which runs Junos OS, that makes the device inaccessible. With a rescue configuration saved on the device, you can return the router/firewall to a known operational state. The rescue configuration saved on the device can provide a last resort means of quickly restoring the device to operational status. You can use either the web-based graphical user interface (GUI) method to create a saved rescue configuration via a web browser connection to the system or a command line interface (CLI) method.
