The value of this object is used to determine when
to generate a pingProbeFailed NOTIFICATION.
Setting BIT probeFailure(0) of object
pingCtlTrapGeneration to '1' implies that a
pingProbeFailed NOTIFICATION is generated only when
a number of consecutive ping probes equal to the
value of pingCtlTrapProbeFailureFilter fail within
a given ping test. After triggering the notification,
the probe failure counter is reset to zero.
