********* THIS OBJECT IS OBSOLETE *********

This object arms and disarms events. The notification node, the associated event object, threshold, hysteresis, and time interval should all be set before an event is armed. The objects do not need to be re-set if the existing values are acceptable. The device will refuse to arm an event with uninitialized objects. Once armed, if the threshold is met or exceeded during the event time interval, a trap PDU is sent to the eventNotificationNode. Subsequently, the monitored object must fall to or below the hysteresis before another trap can be sent via the threshold mechanism. The hysteresis may equal threshold. Events are implicitly rearmed, that is, once an event occurs, it is rearmed. Setting this object to 'on' will result in a genErr in any of the following cases: object not set; cannot set an event on this object; time interval not set; threshold not set.
