How to Perform the ISSU Process
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 loadversion or runversion state, as the following example illustrates:
Switch# show issu state detail
Slot = 5
RP State = Active
ISSU State = Load Version
Operating Mode = Stateful Switchover
Current Image = bootflash:old_image
Pre-ISSU (Original) Image = bootflash:old_image
Post-ISSU (Targeted) Image = bootflash:new_image
Slot = 6
RP State = Standby
ISSU State = Load Version
Operating Mode = Stateful Switchover
Current Image = bootflash:new_image
Pre-ISSU (Original) Image = bootflash:old_image
Post-ISSU (Targeted) Image = bootflash:new_image
Switch# show issu rollback-timer
Rollback Process State = Not in progress
Configured Rollback Time = 60:00
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# issu set rollback-timer 20
% ISSU state should be [ init ] to set the rollback timer
