Statistics Description
dot3StatsAlignment
Errors
A count of frames received on a particular interface that are not an inte-
gral number of octets in length and do not pass the Frame Check
Sequence (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
Logical Link Control (LLC) (or other MAC user). Received frames for
which multiple error conditions obtained are, according to the conven-
tions of IEEE 802.3 Layer Management, counted exclusively according
to the error status presented to the LLC.
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 con-
ditions obtained are, according to the conventions of IEEE 802.3 Layer
Management, counted exclusively according to the error status presented
to the LLC.
Note: Values in this statistics counter usually indicate a bad cable.
