This read-create MepDestinationType object, applicable only to point-to-multipoint probes per its description, indicates whether the destination MEP is identified via the esaProbeDestinationMepId object or by another method such as MAC address. An administrator sets this to tell the device which of the two destination-identification objects on this row should actually be used to reach the remote MEP. For example, an operator without CC protocol enabled between endpoints would set esaProbeDestinationMepType to indicate MAC-address-based identification instead of MEP ID.
