Chapter 5 Configuring the Cisco IOS In-Service Software Upgrade Process Performing the ISSU Process
Entering the issu commitversion command at this stage is equal to entering both the issu acceptversion
and the issu commitversion commands. Use the issu commitversion command if you do not intend to
run in the current state now and are satisfied with the new software version.
Note The rollback timer can be configured only in the ISSU Init state.
Perform this task to configure the rollback timer:
This example shows how to set the rollback timer to 3600 seconds:
Switch> enable
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# issu set rollback-timer 3600
% Rollback timer value set to [ 3600 ] seconds
Switch(config)# exit
Switch# show issu rollback-timer
Rollback Process State = Not in progress
Configured Rollback Time = 60:00
The rollback timer cannot be set in LV state, as the following example illustrates:
Switch# show issu state detail
Slot = 1
RP State = Active
ISSU State = Load Version
Boot Variable = bootflash:old_image,12
Operating Mode = RPR
Primary Version = bootflash:old_image
Secondary Version = bootflash:new_image
Current Version = bootflash:old_image
Slot = 2
RP State = Standby
ISSU State = Load Version
Boot Variable = bootflash:new_image,12;bootflash:old_image,12
Operating Mode = RPR
Primary Version = bootflash:old_image
Secondary Version = bootflash:new_image
Current Version = bootflash:new_image
Switch# show issu rollback-timer
Rollback Process State = Not in progress
Configured Rollback Time = 60:00
