This object specifies the major node threshold for the WPAN RPL table. When the value of the corresponding instance of cwpanIfRplTableNodes is greater than this value, a cwpanRisingIfRplTblMajorThreshNodesNotif notification will be generated. After a cwpanRisingIfRplTblMajorThreshNodesNotif is generated, another such notification will not be generated if the value of the corresponding instance of cwpanIfRplTableNodes stays above this value. When the value of the corresponding instance of cwpanIfRplTableNodes becomes less than or equal to this value after a cwpanRisingIfRplTblMajorThreshNodesNotif notification is generated, a cwpanFallingIfRplTblMajorThreshNodesNotif notification will be generated. After a cwpanFallingIfRplTblMajorThreshNodesNotif is generated, another such notification will not be generated if the value of the corresponding instance of cwpanIfRplTableNodes does not exceed this value.
