Description
A count of frames received on a particular interface that
exceed the maximum permitted frame size. The count
represented by an instance of this object is incremented
when the frameTooLong status is returned by the MAC
service to the LLC (or other MAC user). Received frames for
which multiple error conditions occur 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 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.
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
MultipleCollisionFrames 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
SingleCollisionFrames 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 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.
