	STATUS mandatory
	DESCRIPTION "A count of frames received on a particular

a particular interface for which transmission
is inhibited by exactly one collision.

A frame that is counted by an instance of this

dot3StatsSQETestErrors OBJECT-TYPE
	SYNTAX Counter

message is generated by the PLS sublayer for a
particular interface. The SQE TEST ERROR

collisions."

dot3StatsLateCollisions OBJECT-TYPE
	SYNTAX Counter
	ACCESS read-only
	STATUS mandatory
	DESCRIPTION "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."
	::= { dot3StatsEntry 8 }


dot3StatsExcessiveCollisions OBJECT-TYPE
	SYNTAX Counter
	ACCESS read-only
	STATUS mandatory

dot3StatsInternalMacTransmitErrors OBJECT-TYPE
	SYNTAX Counter
	ACCESS read-only
	STATUS mandatory
	DESCRIPTION "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."

dot3StatsCarrierSenseErrors OBJECT-TYPE
	SYNTAX Counter
	ACCESS read-only
	STATUS mandatory
	DESCRIPTION "The number of times that the carrier sense
condition was lost or never asserted when
attempting to transmit a frame on a particular
interface.

transmission attempt, even if the carrier sense
condition fluctuates during a transmission
attempt."

dot3StatsFrameTooLongs OBJECT-TYPE
	SYNTAX Counter
	ACCESS read-only
	STATUS mandatory
	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 obtain are,
according to the conventions of IEEE 802.3
Layer Management, counted exclusively according

counted by an instance of this object if it is
not counted by the corresponding instance of
either the dot3StatsFrameTooLongs object, the
dot3StatsAlignmentErrors object, or the
dot3StatsFCSErrors 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 receive errors
on a particular interface that are not
otherwise counted."
	::= { dot3StatsEntry 16 }


dot3StatsEtherChipSet OBJECT-TYPE
	SYNTAX OBJECT IDENTIFIER
	ACCESS read-only
	STATUS mandatory
	DESCRIPTION "This object contains an OBJECT IDENTIFIER
which identifies the chipset used to
realize the interface. Ethernet-like
interfaces are typically built out of
several different chips. The MIB implementor
is presented with a decision of which chip
to identify via this object. The implementor
should identify the chip which is usually
called the Medium Access Control chip.
If no such chip is easily identifiable,
the implementor should identify the chip
which actually gathers the transmit
and receive statistics and error
indications. This would allow a
manager station to correlate the
statistics and the chip generating
them, giving it the ability to take
into account any known anomalies
in the chip."

dot3CollTable OBJECT-TYPE
	SYNTAX SEQUENCE OF Dot3CollEntry

	ACCESS read-only
	STATUS mandatory

represents the frequency on a particular
interface."

dot3CollFrequencies OBJECT-TYPE
	SYNTAX Counter
	ACCESS read-only
	STATUS mandatory
	DESCRIPTION "A count of individual MAC frames for which the
transmission (successful or otherwise) on a
particular interface occurs after the
frame has experienced exactly the number
of collisions in the associated
dot3CollCount object.

For example, a frame which is transmitted
on interface 77 after experiencing
exactly 4 collisions would be indicated
by incrementing only dot3CollFrequencies.77.4.
No other instance of dot3CollFrequencies would
be incremented in this example."
