Upgrading and Managing Cisco IOS XR Software

Rolling Back to a Specific Rollback Point

You can roll back to a specific rollback point, including a noncommitted software set:
• If you roll back to the most recent noncommitted rollback point (with the highest number), you do not
• You can repeat the rollback process one rollback point at a time without reloading if you always choose
• If you choose a rollback point that is older than the most recent point, the impacted nodes reload,
In the following example, the system is rolled back to noncommitted rollback point 8:
RP/0/RSP0/CPU0:router(admin)# install rollback to 8
Install operation 10 'install rollback to 8' started by user 'cisco' at 07:49:26
UTC Mon Nov 14 2009.
The install operation will continue asynchronously.

interrupting data traffic on those nodes. Before the reload occurs, you are prompted to confirm the install
rollback operation.
The changes made to software configurations will not be persistent
across system reloads. Use the command 'admin install commit' to make
changes persistent.
Please verify that the system is consistent following the software
change using the following commands:
show system verify
install verify packages
The rollback to committed software will require a reload of impacted
nodes because it is over multiple activation & deactivation
operations.
This operation will reload the following node:
0/RP1/CPU0 (RP) (SDR: Owner)
This operation will reload all RPs in the Owner SDR, and thereby
indirectly cause every node in the router to reload.
The changes made to software configurations will not be persistent
across system reloads. Use the command 'admin install commit' to make
changes persistent.
Please verify that the system is consistent following the software
change using the following commands:
show system verify
install verify packages
