Release Information
Command introduced before Junos OS Release 7.4.
Command introduced in Junos OS Release 9.0 for EX Series switches.
Option sfc introduced for the TX Matrix Plus router in Junos OS Release 9.6.
Command introduced in Junos OS Release 11.1 for the QFX Series.
Command behavior changed in Junos OS Release 12.1.
Option reboot introduced in Junos OS Release 12.3.
Description
For all versions of Junos OS up to and including Junos OS 11.4, revert to the software that was loaded at the last successful request system software add command.
As of Junos OS 12.1 and greater, revert to the last known good state before the most recent request system software (add | delete) command. For example, using rollback in Junos OS 12.1 after using request system software add restores the system to a known good state prior to using the add command. Similarly, using rollback in Junos OS 12.1 after using request system software delete restores the system to a known good state prior to using the delete command.
A software rollback fails if any required package (or a jbundle package containing the required package) cannot be found in /var/sw/pkg.
Additional Information
- On M Series and T Series routers, if request system software add <jinstall> reboot was used for the previous installation, then request system software rollback has o effect. In this case, use jinstall to reinstall the required package.
- On M Series and T Series routers, if request system software add <sdk1> was used for the previous installation, then request system software rollback removes the last installed SDK package (sdk1 in this example).
- On SRX Series devices with dual root systems, when request system software rollback is run, the system switches to the alternate root. Each root can have a different version of Junos OS. Rollback takes each root back to the previously installed image.
