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.
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.
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.
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 Mb/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.
