A frame is only counted by an instance of this object if it is not counted by the corresponding instance of either the dot3StatsLateCollisions object, the dot3StatsExcessiveCollisions object, or the dot3StatsCarrierSenseErrors object. The precise meaning of the count represented by an instance of this object is implementation- specific.

For ethernet-like interfaces, this test -- configures the MAC chip and executes an internal loopback -- test of memory and the MAC chip logic.
