HP BMD00022 manual Dot3StatsMultipleCollisionFrames, Dot3StatsSingleCollisionFrames object

Table 48 Ethernet statistics for port

Statistics	Description
dot3StatsMultipleCollisionFrames	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.
dot3StatsLateCollisions	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 Mbps 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.
dot3StatsExcessiveCollisions	A count of frames for which transmission on a particular
	interface fails due to excessive collisions.
dot3StatsInternalMacTransmitErrors	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.
dot3StatsFrameTooLongs	A count of frames received on a particular interface that
	exceeds 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 obtained
	are, according to the conventions of IEEE 802.3 Layer
	Management, counted exclusively according to the error
	status presented to the LLC.
