} dot3StatsIndex OBJECT-TYPE SYNTAX INTEGER ACCESS read-only STATUS mandatory DESCRIPTION "An index value that uniquely identifies an interface to an ethernet-like medium. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex." ::= { dot3StatsEntry 1 } dot3StatsAlignmentErrors OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory 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." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 2 }Kastenholz [Page 7] RFC 1623 Ethernet-Like MIB May 1994 dot3StatsFCSErrors OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory 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. 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." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 3 } dot3StatsSingleCollisionFrames OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory 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." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 4 } dot3StatsMultipleCollisionFrames OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "A count of successfully transmitted frames on a particular interface for which transmissionKastenholz [Page 8] RFC 1623 Ethernet-Like MIB May 1994 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." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 5 } dot3StatsSQETestErrors OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory 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 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." REFERENCE "ANSI/IEEE Std 802.3-1985 Carrier Sense Multiple Access with Collision Detection Access Method and Physical Layer Specifications" ::= { dot3StatsEntry 6 } dot3StatsDeferredTransmissions OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory 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." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 7 } dot3StatsLateCollisions OBJECT-TYPEKastenholz [Page 9] RFC 1623 Ethernet-Like MIB May 1994 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." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 8 } dot3StatsExcessiveCollisions OBJECT-TYPE SYNTAX Counter ACCESS read-only STATUS mandatory DESCRIPTION "A count of frames for which transmission on a particular interface fails due to excessive collisions." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 9 } 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 byKastenholz [Page 10] RFC 1623 Ethernet-Like MIB May 1994 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." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 10 } 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. The count represented by an instance of this object is incremented at most once per transmission attempt, even if the carrier sense condition fluctuates during a transmission attempt." REFERENCE "IEEE 802.3 Layer Management" ::= { dot3StatsEntry 11 } -- { dot3StatsEntry 12 } is not assigned 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 to the error status presented to the LLC."

A frame is only 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." REFERENCE "IEEE 802.3 Layer Management" ::= { 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 transmitKastenholz [Page 12] RFC 1623 Ethernet-Like MIB May 1994 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." ::= { dot3StatsEntry 17 } -- the Ethernet-like Collision Statistics group -- Implementation of this group is optional; it is appropriate -- for all systems which have the necessary metering dot3CollTable OBJECT-TYPE SYNTAX SEQUENCE OF Dot3CollEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "A collection of collision histograms for a particular set of interfaces." ::= { dot3 5 } dot3CollEntry OBJECT-TYPE SYNTAX Dot3CollEntry ACCESS not-accessible STATUS mandatory DESCRIPTION "A cell in the histogram of per-frame collisions for a particular interface.
