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
another MAC user). Received frames, for which
multiple error conditions obtained are counted,
according to the conventions of IEEE 802.3 Layer
Management, 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
either the ifOutUcastPkts, ifOutMulticastPkts,
or ifOutBroadcastPkts objects and is not
counted by the corresponding instance of the
dot3StatsMultipleCollisionFrames 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; 512 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.
The total number of frames that are too short that
were encountered on this interface.
The total number of link failures encountered on
this interface.
