	backup role.
	This text after the slash displays the monitored interface’s status in the virtual router.

	Stand-By- This interface is a backup interface in the virtual router. It is not using the
	virtual IP address and subnet mask.
	Fault - This interface is not functioning in the virtual router right now. In active-passive
	mode , if one of the master ZyWALL’s interfaces loses its connection, the master ZyWALL
	forces all of its interfaces to the fault state so the backup ZyWALL can take over all of the
	master ZyWALL’s functions.
