Description
A count of frames received on a particular interface that are not an
integral number of octets in length and do not pass the Frame Check
Sequence (FCS) check.
The count represented by an instance of this object is incremented
when the alignmentError status is returned by the MAC service to the
Logical Link Control (LLC) (or other MAC user).
Received frames for which multiple error conditions obtained are,
according to the conventions of IEEE 802.3 Layer Management,
counted exclusively according to the error status presented to the LLC.
A count of frames received on a particular interface that are an
integral number of octets in length but do not pass the Frame Check
Sequence (FCS) check.
The count represented by an instance of this object is incremented
when the frameCheckError status is returned by the MAC service to the
LLC (or other MAC user).
Received frames for which multiple error conditions obtained are,
according to the conventions of IEEE 802.3 Layer Management,
counted exclusively according to the error status presented to the LLC.
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 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 sublayer 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.
