Switch# show redundancy states
my state = 13 -ACTIVE
peer state = 8 -STANDBY HOT
Mode = Duplex
Unit = Primary
Unit ID = 1
Redundancy Mode (Operational) = Stateful Switchover
Redundancy Mode (Configured) = Stateful Switchover
Redundancy State = Stateful Switchover
Maintenance Mode = Disabled
Manual Swact = enabled

The following example shows how the forced option places the system in RPR mode:
Switch> enable
Switch# issu loadversion 1 bootflash:new_image 2 slavebootflash:new_image forced
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
The following example shows the redundancy mode as RPR:
Switch# show redundancy states
my state = 13 -ACTIVE
peer state = 4 -STANDBY COLD
Mode = Duplex
Unit = Primary
Unit ID = 1
Redundancy Mode (Operational) = RPR
Redundancy Mode (Configured) = Stateful Switchover
Redundancy State = RPR
Maintenance Mode = Disabled
Manual Swact = enabled
Communications = Up
