DESCRIPTION "The MIB module to describe generic objects for
Ethernet-like network interfaces.
The following reference is used throughout this
MIB module:
[IEEE 802.3 Std] refers to:
IEEE Std 802.3, 1998 Edition: 'Information
technology - Telecommunications and
information exchange between systems -
Local and metropolitan area networks -
Specific requirements - Part 3: Carrier
sense multiple access with collision
detection (CSMA/CD) access method and
physical layer specifications',
September 1998.
Of particular interest is Clause 30, '10Mb/s,
100Mb/s and 1000Mb/s Management'."
REVISION "9908240400Z" -- August 24, 1999
DESCRIPTION "Updated to include support for 1000 Mb/sec
interfaces and full-duplex interfaces.
This version published as RFC 2665."
REVISION "9806032150Z"
DESCRIPTION "Updated to include support for 100 Mb/sec
interfaces.
This version published as RFC 2358."

this index is the same interface as identified
by the same value of ifIndex."
REFERENCE "RFC 2233, ifIndex"
::= { dot3StatsEntry 1 }
dot3StatsAlignmentErrors OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
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 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
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
to the error status presented to the LLC.
This counter does not increment for 8-bit wide
group encoding schemes.
Discontinuities in the value of this counter can
occur at re-initialization of the management
system, and at other times as indicated by the
value of ifCounterDiscontinuityTime."

aAlignmentErrors"
::= { dot3StatsEntry 2 }
dot3StatsFCSErrors OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION "A count of frames received on a particular
interface that are an integral number of octets
in length but do not pass the FCS check. This
count does not include frames received with
frame-too-long or frame-too-short error.
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 obtain are,
according to the conventions of IEEE 802.3
Layer Management, counted exclusively according
to the error status presented to the LLC.
Note: Coding errors detected by the physical
layer for speeds above 10 Mb/s will cause the
frame to fail the FCS check.
Discontinuities in the value of this counter can
occur at re-initialization of the management
system, and at other times as indicated by the
value of ifCounterDiscontinuityTime."

::= { dot3StatsEntry 3 }
dot3StatsSingleCollisionFrames OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION "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 dot3StatsMultipleCollisionFrames
object.
This counter does not increment when the
interface is operating in full-duplex mode.
Discontinuities in the value of this counter can
occur at re-initialization of the management
system, and at other times as indicated by the
value of ifCounterDiscontinuityTime."
REFERENCE "[IEEE 802.3 Std.], 30.3.1.1.3,
aSingleCollisionFrames."
::= { dot3StatsEntry 4 }
dot3StatsMultipleCollisionFrames OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION "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.
This counter does not increment when the
interface is operating in full-duplex mode.
Discontinuities in the value of this counter can
occur at re-initialization of the management
system, and at other times as indicated by the
value of ifCounterDiscontinuityTime."

::= { dot3StatsEntry 5 }
dot3StatsSQETestErrors OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION "A count of times that the SQE TEST ERROR
message is generated by the PLS sublayer for a
particular interface. The SQE TEST ERROR
is set in accordance with the rules for
verification of the SQE detection mechanism in
the PLS Carrier Sense Function as described in
IEEE Std. 802.3, 1998 Edition, section 7.2.4.6.
This counter does not increment on interfaces
operating at speeds greater than 10 Mb/s, or on
interfaces operating in full-duplex mode.
Discontinuities in the value of this counter can
occur at re-initialization of the management
system, and at other times as indicated by the
value of ifCounterDiscontinuityTime."
REFERENCE "[IEEE 802.3 Std.], 7.2.4.6, also 30.3.2.1.4,

::= { dot3StatsEntry 6 }
dot3StatsDeferredTransmissions OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION "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.
