Ethernet-Like MIB (RFC 1643)
dot3StatsSingleCollision
Frames
TX
Packets successfully transmitted after
one and only one collision (i.e.: attempt
value=2). Equivalent to
“aSingleCollisionFrames”
Packets successfully transmitted after
more than one collision (i.e.: 2<attempt
value<16). Equivalent to
“aMultipleCollisionFrames”
Packets with CRC error only. Equivalent
to “aFrameCheckSequenceErrors”
Packets with alignment error only.
Equivalent to “aAlignmentErrors”
Packets deferred, i.e. packets whose
transmission was delayed due to busy
medium, on first attempt only. This does
not include collisions. Equivalent to
“aFramesWithDeferredXmissions”
Packets that encounter a late collision,
i.e. encountered collisions more than
512 bit times into transmitted packet. A
late collision is counted twice, as a col-
lision and a late collision. Equivalent to
“aLateCollisions”
