Ethernet Statistics of a Port (continued)
Description
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
dot3StatsMultipleCollisionFrame 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, and is not counted by the
corresponding instance of the
dot3StatsSingleCollisionFrames object.
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.
A count of frames for which transmission on a
particular interface fails due to excessive collisions.
A count of frames for which transmission on a
particular interface fails due to an internal MAC sub
layer 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.
