Statistics	Description
dot3StatsFCSErrors	A count of frames received on a particular interface that are an
	integral number of octets in length but do not pass the Frame
	Check Sequence (FCS) check.
	The count represented by an instance of this object is incremented
	when the frameCheckError status is returned by the MAC
	service to the LLC (or other MAC user).
	Received frames for which multiple error conditions obtained are,
	according to the conventions of IEEE 802.3 Layer Management,
	counted exclusively according to the error status presented to the
	LLC.
dot3StatsSingleCollisionFrames	A count of successfully transmitted frames on a particular interface
	for which transmission is inhibited by exactly one collision.
	A frame that is counted by an instance of this object is also
	counted by the corresponding instance of the ifOutUcastPkts,
	ifOutMulticastPkts, or ifOutBroadcastPkts, and is not
	counted by the corresponding instance of the
	dot3StatsMultipleCollisionFrame object.
dot3StatsMultipleCollisionFrames	A count of successfully transmitted frames on a particular interface
	for which transmission is inhibited by more than one collision.
	A frame that is counted by an instance of this object is also
	counted by the corresponding instance of either the
	ifOutUcastPkts, ifOutMulticastPkts, or
	ifOutBroadcastPkts, and is not counted by the corresponding
	instance of the dot3StatsSingleCollisionFrames object.
dot3StatsLateCollisions	The number of times that a collision is detected on a particular
	interface later than 512 bit-times into the transmission of a packet.
	Five hundred and twelve bit-times corresponds to 51.2
	microseconds on a 10 Mbps system. A (late) collision included in a
	count represented by an instance of this object is also considered
	as a (generic) collision for purposes of other collision-related
	statistics.
dot3StatsExcessiveCollisions	A count of frames for which transmission on a particular interface
	fails due to excessive collisions.
dot3StatsInternalMacTransmitErrors	A count of frames for which transmission on a particular interface
	fails due to an internal MAC sublayer transmit error.
	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. In particular, an instance of this
	object may represent a count of transmission errors on a particular
	interface that are not otherwise counted.
