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:
•
•
The issu acceptversion command can be optionally executed after the issu runversion command.
Note

Time information indicates the amount of time remaining before an automatic rollback occurs.

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.

ISSU process is not automatically aborted during the ISSU
process.
Enter the issu acceptversion command within the time

and the system reverts to the previous version of Cisco IOS
software by switching to the standby supervisor engine.
