Rolling Back to a Previous Software Set

Cisco IOS XR software allows you to roll back one or more SDRs to a previous committed or uncommitted
software set. Use the show install rollback ? command to view the available rollback points and use the
install rollback to command to roll back the SDR to a previous software set. You can also use the install
rollback to committed command to roll back to the most recent committed software set.
Note Rollback operations can be performed by running the command in administration EXEC or EXEC mode.

Displaying Rollback Points

A rollback point is created every time a software package is activated, deactivated, or committed. Use the
show install rollback ? command to display the eligible rollback points.
