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:
•
•
Note The issu acceptversion command may be optionally executed after the issu runversion command.
Command or Action
Step 1
Switch> enable
Step 2
Switch# issu acceptversion [active-slot]
[active-image-new]]
Step 3
Switch# show issu rollback-timer
This example displays the Timer before you stop it. In the following example, the "Automatic Rollback
Time" information indicates the amount of time remaining before an automatic rollback will occur.
Switch> enable
Switch# show issu rollback-timer
Configured Rollback Time = 00:45:00
Switch# issu acceptversion 6 bootflash:new_image

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.
Rollback Process State = 00:31:09 remaining
Purpose
Enables privileged EXEC mode.
Enter your password if prompted.
Halts the rollback timer and ensures the new Cisco IOS XE
ISSU process is not automatically aborted during the ISSU
process.
Enter the issu acceptversion command within the time
period specified by the rollback timer to acknowledge that
the supervisor engine has achieved connectivity to the
outside world; otherwise, the ISSU process is terminated,
when the rollback timer expires, and the system reverts to
the previous version of Cisco IOS XE software by switching
to the standby supervisor engine.
Displays the amount of time left before an automatic
rollback will occur.
