Graphing multilink trunk statistics 67
Field Description
SQETestError A count of times that the SQE TEST
ERROR message is generated by the
PLS sublayer for a particular MLT. 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.
DeferredTransmiss A count of frames for which the first
transmission attempt on a particular MLT is
delayed because the medium is busy. The
count represented by an instance of this
object does not include frames involved in
collisions.
SingleCollFrames A count of successfully transmitted frames
on a particular MLT 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 MultipleCollisionFrames
object.
MultipleCollFrames A count of successfully transmitted frames
on a particular MLT 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 SingleCollisionFrames
object.
LateCollisions The number of times that a collision is
detected on a particular MLT 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.
ExcessiveColls A count of frames for which transmission
on a particular MLT fails due to excessive
collisions.
