Statistics Description
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 conditions obtained are,
according to the conventions of IEEE 802.3 Layer Management,
counted exclusively according to the error status presented to the
LLC.
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 the ifOutUcastPkts,
ifOutMulticastPkts, or ifOutBroadcastPkts, and is not counted by
the corresponding instance of the dot3StatsMultipleCollisionFrame
object.
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.
dot3StatsLateCollisions The number of times that a collision is detected on a particular
interface later than 512 bit-times into the transmission of a packet.
Five hundred and twelve bit-times corresponds to 51.2
microseconds on a 10 Mbit/s system. 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.
dot3StatsExcessiveCollisions A count of frames for which transmission on a particular interface
fails due to excessive collisions.
dot3StatsInternalMacTransmitErrors A count of frames for which transmission on a particular interface
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
dot3StatsLateCollisions object, the dot3StatsExcessiveCollisions
object, or the dot3StatsCarrierSenseErrors 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 transmission errors on a
particular interface that are not otherwise counted.
dot3StatsFrameTooLongs A count of frames received on a particular interface that exceeds
the maximum permitted frame size.
The count represented by an instance of this object is incremented
when the frameTooLong status is returned by the MAC service to
the LLC (or other MAC user).
Received frames for which multiple error conditions obtained are,
according to the conventions of IEEE 802.3 Layer Management,
counted exclusively according to the error status presented to the
LLC.
