Parameters
point-id: Specifies a rollback point ID. This option is supported only when there are two or more
rollback points. To identify available rollback points, use the display install rollback command.
original: Rolls back to the status before any activate or deactivate operations were performed.
Usage guidelines
During an incremental upgrade, the system creates a rollback point for each activate or deactivate
operation of a boot, system, or feature image. The device supports a maximum of 50 rollback points.
The earliest rollback point is deleted if this limit has been reached when a rollback point is created.
During a reboot upgrade, the system does not create rollback points. After a reboot upgrade, you can
roll back the software only to the status before any activate or deactivate operations were performed.
For a rollback to take effect after a reboot, you must perform a commit operation to update the main
startup software image list.
After a commit operation is performed, you cannot perform a rollback.
Patch images do not support rollback.
Examples
# Roll back the software to rollback point 1.
<Sysname>install rollback to 1
This operation might take several minutes, please wait...Done.
# Roll back the software to the original software versions and observe the change made by the
rollback.
