Parameters
point-id: Specifies a rollback point ID. This option is supported only when there are two or more
rollback points. To view available rollback points, use the display install rollback command.
original: Rolls back to the software images that were running before the ISSU.
Usage guidelines
The system creates a rollback point for each service or file upgrade performed through activate or
deactivate operation. The rollback points are retained until any of the following events occur:
•
An ISSU reboot or reboot upgrade is performed.
•
The install commit command is executed.
After an ISSU reboot or reboot upgrade is performed, you can roll back the running software images
only to the status before any activate or deactivate operations were performed.
After a commit operation is performed, you cannot perform a rollback.
For a rollback to take effect after a reboot, you must perform a commit operation to update the main
startup software image list.
A maximum of 50 rollback points are available for service and file upgrades. The earliest rollback
point is removed if this limit has been reached when a rollback point is created.
Patch images do not support rollback.
Examples
# Roll back the software to rollback point 1.
<Sysname>install rollback to 1
# Roll back the software to the original software versions and observe the change made by the
