request system software rollback (Junos OS Evolved)



Use this command to revert to the last successfully installed package before the last-issued request system software (add | delete) command. By default, once the software is rolled back, the device uses the current configuration file. You can use this command on either Routing Engine in a dual-Routing Engine system.

On Junos OS Evolved, the reboot option is required in order to complete the rollback.


package-name version

Select any installed version for the rollback. The request system software rollback operational mode command uses the version instead of the package-name. You can see the available versions by using the show system software list operational mode command. If you do not specify the version, the system rolls back to the default rollback version (the one with the '<' before it on the show system software list command output). You can specify any previous Junos OS Evolved release as long as it is neither the one that is currently running nor the rollback version.


Do not check compatibility with the current configuration.

Default: validate


(Optional) Reboot to complete the rollback. If you do not specify the reboot option, then when this command completes, you need to issue the request system reboot operational mode command to reboot the system to finish the rollback process.


(Optional) Rolls back the system to the specified version with the old snapshot of the configuration used in that version. Otherwise, the rollback, by default, takes the current configuration.
