Description
AlignmentErrors
A count of frames received on a particular interface that are 
not an integral number of octets in length and do not pass the 
FCS check. The count represented by an instance of this 
object is incremented when the alignmentError status is 
returned by the MAC service to the LLC (or other MAC user). 
Received frames for which multiple error conditions obtain 
are, according to the conventions of IEEE 802.3 Layer 
Management, counted exclusively according to the error 
status presented to the LLC.
FCSErrors
A count of frames received on a particular interface that are 
an integral number of octets in length but do not pass the 
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.
InternalMacTransmitErrors 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.
InternalMacReceiveErrors 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 
either 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 
receive errors on a particular interface that are not otherwise 
counted.
