This example shows how to set the rollback timer to 3600 seconds:
Switch> enable
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# issu set rollback-timer 3600
% Rollback timer value set to [ 3600 ] seconds
Switch(config)# exit
Switch# show issu rollback-timer
The Rollback Timer cannot be set in loadversion or runversion state, as the following example illustrates:
Switch# show issu state detail
Switch# show issu rollback-timer
Switch# configure terminal
Enter configuration commands, one per line.
Switch(config)# issu set rollback-timer 20
% ISSU state should be [ init ] to set the rollback timer
