On the J Series router, you can use this command to roll back to a previous software package when the current upgrade has been successful or has failed. On M Series and T Series routers, use this command only to recover from a failed software upgrade—you cannot issue this command to return to the previously installed software after using a jinstall package. To return to the previously installed software, use the corresponding jinstall package.
A software rollback fails if any required package (or a jbundle package containing the required package) cannot be found in /var/sw/pkg.
