Table 48 Ethernet statistics for port

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 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 Mbit/s 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 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.

dot3StatsFrameTooLongs	A count of frames received on a particular interface that exceeds the
	maximum permitted frame size.
	The count represented by an instance of this object is incremented when
	the frameTooLong 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.
dot3StatsInternalMacReceiveErrors	A count of frames for which reception on a particular interface fails due
	to an internal MAC sublayer receive error.
	A frame is only counted by an instance of this object if it is not counted
	by the corresponding instance of the dot3StatsFrameTooLongs object,
	the dot3StatsAlignmentErrors object, or the dot3StatsFCSErrors 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 received errors on a particular interface that
	are not otherwise counted.
