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.
