Dot3 Stats Single
Collision Frames 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
dot3StatsMultipleCollisionFrames object.
This counter does not increment when the interface is
operating in full-duplex mode.
Dot3 Stats
Deferred
Transmissions 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.
This counter does not increment when the interface is
operating in full-duplex mode.
Switch Stats In
Bad Octets Total data octets received in frames with a invalid FCS.
Fragments and jabbers are included. The count includes the
FCS but not the preamble.
Switch Stats
Undersized
Frames Total frames received with a length of less than 64 octets
buts with a valid FCS.
Switch Stats In
Fragments Total frames received with a length of less than 64 octets
and an invalid FCS.
Switch Stats In 64
Octets Total frames received with a length of exactly 64 octets,
including those with errors.
Switch Stats In
127 Octets Total frames received with a length of between 65 and 127
octets inclusive, including those with errors.
Switch Stats In
255 Octets Total frames received with a length of between 128 and 255
octets inclusive, including those with errors.
Switch Stats In
511 Octets Total frames received with a length of between 256 and 511
octets inclusive, including those with errors.
Switch Stats In
1023 Octets Total frames received with a length of between 512 and
1023 octets inclusive, including those with errors.
Switch Stats In
Max Octet Total frames received with a length of between 1024 and
MaxSize octets inclusive, including those with errors.
Switch Stats In
Jabber Total frames received with a length of more than MaxSize
octets but with an invalid FCS.
Switch Stats Out
FCS Errored Total frames transmitted with an invalid FCS. Whenever a
frame is modified (such as to add or remove a tag) and a
new FCS is computed for the frame, before the new FCS is
added into the frame the old FCS is inspected to insure the
original unmodified frame was still good. If an error is
detected the new FCS is added with a bad FCS and Switch
Stats Out FCS Errored is incremented.
