The backup unit takes overas the new management unit without clearing the hardware state on any ofthe stack members. The original management unit reboots. If the system isnot ready for a warm restart, for example because no backup unit has beenelected or one or more members of the stack do not support nonstopforwarding, the command fails with a warning message. Use the standbycommand to select a specific unit to act as the backup unit. Use the show nsfcommand to check the NSF state. If the switch shows Warm Restart Ready asYes, then the master switch state is synchronized with the standby switch.ExamplesExample-No Stack Port Errorsconsole(config-stack)#initiate failover ?
