Switch# show redundancy states
Redundancy Mode (Operational) = Stateful Switchover
Redundancy Mode (Configured) = Stateful Switchover
Communications = Up
client_notification_TMR = 240000 milliseconds
The following example shows how the forced option places the system in RPR mode:
Switch> enable
Switch# issu loadversion 5 bootflash:new_image 6 slavebootflash:new_image forced
%issu loadversion executed successfully, Standby is being reloaded
Switch# show issu state detail
The following example shows the redundancy mode as RPR:
