Port Statistic Description
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 collision-
related statistics. This counter does not increment when the interface is
operating in full-duplex mode.
