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 XE 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 the runversion state for an extended period, you need to stop the
rollback timer by entering the acceptversion command. Then validate the new software and enter
the commitversion command (as described in the following section).
• If you want to proceed with the commitversion operation within the rollback timer window of 45
minutes (or the configured value), you do not need to use the acceptversion command to stop the
roll-back timer.
Note The issu acceptversion command may be optionally executed after the issu runversion command.
