Definition
A count of frames received on a particular interface
that are not an integral 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 LLC (or other MAC
user). Received frames for which multiple error
conditions exist are, according to the conventions of
IEEE 802.3 Layer Management, counted exclusively
according to the error status presented to the LLC.
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 occur are,
according to the conventions of IEEE 802.3 Layer
Management, counted exclusively according to the
error status presented to the LLC.
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 either the ifOutUcastPkts
object, the ifOutMulticastPkts object, or the
ifOutBroadcastPkts object, and is not counted by
the corresponding instance of the
dot3StatsMultipleCollisionFrames object.
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 either the ifOutUcastPkts,
ifOutMulticastPkts, or ifOutBroadcastPkts object, and
is not counted by the corresponding instance of the
dot3StatsSingleCollisionFrames object.
A count of times that the SQE TEST ERROR
message is generated by the PLS sublayer for a
particular interface. The SQE TEST ERROR message
is defined in section 7.2.2.2.4 of ANSI/IEEE
802.3-1985 and its generation is described in section
7.2.4.6 of the same document.
