    Release Information

    Statement introduced before Junos OS Release 7.4.


    Configure the router to reboot if the software process fails four times within 30 seconds, and specify the software to use during the reboot.


    process-name—Junos OS process name. Some of the processes that support the failover statement are bootp, chassis-control, craft-control, ethernet-connectivity-fault-management, init, interface-control, neighbor-liveness, pfe, redundancy-interface-process, routing, smg-service, and vrrp.

    alternate-media—Use the Junos OS image on alternate media during the reboot.

    other-routing-engine—On routers with dual Routing Engines, use the Junos OS image on the other Routing Engine during the reboot. That Routing Engine assumes mastership; in the usual configuration, the other Routing Engine is the designated backup Routing Engine.
