Table 39 Ethernet Errors tab fields
Field Description
AlignmentErrors A count of frames received on a particular MLT 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 occur 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 an MLT 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 occur are, according to the
conventions of IEEE 802.3 Layer Management, counted
exclusively according to the error status presented to the LLC.
IMacTransmitError A count of frames for which transmission on a particular MLT
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 LateCollisions object,
the ExcessiveCollisions object, or the CarrierSenseErrors
object.
IMacReceiveError A count of frames for which reception on a particular MLT 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 FrameTooLongs object,
the AlignmentErrors object, or the FCSErrors 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.
CarrierSenseErrors The number of times that the carrier sense condition was lost or
never asserted when attempting to transmit a frame on a
particular MLT. The count represented by an instance of this
object is incremented at most once per transmission attempt,
even if the carrier sense condition fluctuates during a
transmission attempt.
