The index of the eventEntry that is used when a successful poll is made after a number of unsuccessful polls. The eventEntry identified by a particular value of this index is the same as identified by the same value of the eventIndex object. If there is no corresponding entry in the eventTable, then no association exists. In particular, if this value is zero, no associated event will be generated, as zero is not a valid event index. This object may not be modified if the associated remPollStatus object is equal to valid(1).
