Parameters
point-id: Specifies a rollback point ID. To view available rollback points, use the display install rollback
command.
original: Rolls back to the software configuration before you perform an ISSU.
Usage guidelines
Every time you activate or deactivate a software image for an incremental upgrade, the system creates
a rollback point to record the current software configuration. Before you execute the install commit
command to confirm the software changes (executing this command also removes all rollback points),
you can roll back the software configuration to a rollback point to cancel all software image
upgrade-related operations performed after the rollback point. You can also roll back the software
configuration to the original software configuration (the software configuration before you performed the
ISSU).
For an incremental upgrade, up to 50 rollback points are supported. After the limit is reached, the oldest
rollback points are deleted to make room for newly created rollback points.
For ISSU upgrades and reboot upgrades, the system does not record and maintain any rollback point,
and you can roll back the software configuration only to the original software configuration.
Patch images do not support rollback.
Examples
# Roll back the software configuration to rollback point 1.
<Sysname>install rollback to 1
# Roll back the software configuration to the original software configuration and observe the change
made by the rollback.
<Sysname> display install active
