Stopping the ISSU Rollback Timer (Optional)
This optional task describes how to stop the rollback timer.
If you do not run the following procedure before the rollback timer “timeout,” the system automatically
aborts the ISSU process and reverts to the original Cisco IOS software version. By default the rollback
timer is 45 minutes.
Use the following information to decide what action you should take:
• If you want to retain your switch in this state for an extended period, you need to stop the rollback
timer (then validate and run the acceptversion command directly).
• If you want to proceed to the following step (running “commitversion”) within the rollback timer
window of 45 minutes, you do not need to stop the rollback timer.
Note The issu acceptversion command can be optionally executed after the issu runversion command.
