Dot3StatsAlignmentErrors
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). According to the conventions of IEEE 802.3 Layer
Management, received frames for which multiple error conditions are
obtained are counted exclusively according to the error status
presented to the LLC. This counter does not increment for 8-bit wide
group encoding schemes.
Dot3StatsFCSErrors
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. This
count does not include frames received with a frame-too-long or frame-
too-short error. 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). According to the conventions of
IEEE 802.3 Layer Management, received frames for which multiple
error conditions are obtained are counted exclusively according to the
error status presented to the LLC. Coding errors detected by the
physical layer for speeds above 10 Mb/s will cause the frame to fail
the FCS check.
Dot3StatsSingleCollisionFrames 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, ifOutMulticastPkts,
or ifOutBroadcastPkts, and is not counted by the corresponding
instance of the dot3StatsMultipleCollisionFrames object. This counter
does not increment when the interface is operating in full-duplex mode.
Dot3StatsMultipleCollisionFrames
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, and is not counted by the corresponding
instance of the dot3StatsSingleCollisionFrames object. This counter
does not increment when the interface is operating in full-duplex mode.
Dot3StatsSQETestErrors
A count of times that the SQE TEST ERROR message is generated by
the PLS sublayer for a particular interface. The SQE TEST ERROR is set
in accordance with the rules for verification of the SQE detection
mechanism in the PLS Carrier Sense Function as described in IEEE Std.
802.3, 1998 Edition, section 7.2.4.6. This counter does not increment
on interfaces operating at speeds greater than 10 Mb/s or operating
in full-duplex mode.
Dot3StatsDeferredTransmissions A
count of frames for which the first transmission attempt on a
particular interface is delayed because the medium is busy. The count
represented by an instance of this object does not include frames
involved in collisions. This counter does not increment when the
interface is operating in full-duplex mode.
Dot3StatsLateCollisions The
number of times that a collision is detected on a particular
interface later than one slotTime into the transmission of a packet. A
(late) collision included in a count represented by an instance of this
object is also considered as a (generic) collision for purposes of other
