           DESCRIPTION "A table containing 64-bit versions of error
                       counters from the dot3StatsTable.  The 32-bit
                       versions of these counters may roll over quite
                       quickly on higher speed ethernet interfaces.
                       The counters that have 64-bit versions in this
                       table are the counters that apply to full-duplex
                       interfaces, since 10 Gb/s and faster
                       ethernet-like interfaces do not support
                       half-duplex, and very few 1000 Mb/s
                       ethernet-like interfaces support half-duplex.

                       Entries in this table are recommended for
                       interfaces capable of operating at 1000 Mb/s or
                       faster, and are required for interfaces capable
                       of operating at 10 Gb/s or faster.  Lower speed
                       ethernet-like interfaces do not need entries in
                       this table, in which case there may be fewer
                       entries in this table than in the
                       dot3StatsTable. However, implementations
                       containing interfaces with a mix of speeds may
                       choose to implement entries in this table for

                       10Base5 and 10Base2.  The TDR value may be
                       useful in determining the approximate distance
                       to a cable fault.  It is advisable to repeat
                       this test to check for a consistent resulting
                       TDR value, to verify that there is a fault.

                       A TDR test returns as its result the time

                       an internal loopback test of memory, data paths,

                       only be executed if the interface is offline.
                       Once the test has completed, the MAC chip should

   This document is based on the Proposed Standard Ethernet MIB, RFC
   2665 [RFC2665], edited by John Flick of Hewlett-Packard and Jeffrey
   Johnson of RedBack Networks and produced by the Ethernet Interfaces
   and Hub MIB Working Group.  It extends that document by providing
   support for 10 Gb/s Ethernet interfaces as defined in [IEEE802.3ae].

   RFC 2665, in turn, is based on the Proposed Standard Ethernet MIB,
   RFC 2358 [RFC2358], edited by John Flick of Hewlett-Packard and
   Jeffrey Johnson of RedBack Networks and produced by the 802.3 Hub MIB
   Working Group.  It extends that document by providing support for
   full-duplex Ethernet interfaces and 1000 Mb/sec Ethernet interfaces
   as outlined in [IEEE802.3].

   RFC 2358, in turn, is almost completely based on both the Standard
   Ethernet MIB, RFC 1643 [RFC1643], and the Proposed Standard Ethernet
   MIB using the SNMPv2 SMI, RFC 1650 [RFC1650], both of which were
   edited by Frank Kastenholz of FTP Software and produced by the
   Interfaces MIB Working Group.  RFC 2358 extends those documents by
   providing support for 100 Mb/sec ethernet interfaces.

   RFC 1643 and RFC 1650, in turn, are based on the Draft Standard
   Ethernet MIB, RFC 1398 [RFC1398], also edited by Frank Kastenholz and
   produced by the Ethernet MIB Working Group.

   RFC 1398, in turn, is based on the Proposed Standard Ethernet MIB,
   RFC 1284 [RFC1284], which was edited by John Cook of Chipcom and
   produced by the Transmission MIB Working Group.  The Ethernet MIB
   Working Group gathered implementation experience of the variables
   specified in RFC 1284, documented that experience in RFC 1369
   [RFC1369], and used that information to develop this revised MIB.

   RFC 1284, in turn, is based on a document written by Frank
   Kastenholz, then of Interlan, entitled IEEE 802.3 Layer Management
   Draft M compatible MIB for TCP/IP Networks [KASTEN].  This document
   was modestly reworked, initially by the SNMP Working Group, and then
   by the Transmission Working Group, to reflect the current conventions
   for defining objects for MIB interfaces.  James Davin, of the MIT
   Laboratory for Computer Science, and Keith McCloghrie of Hughes LAN
   Systems, contributed to later drafts of this memo.  Marshall Rose of
   Performance Systems International, Inc. converted the document into
   RFC 1212 [RFC1212] concise format.  Anil Rijsinghani of DEC
   contributed text that more adequately describes the TDR test.  Thanks
   to Frank Kastenholz of Interlan and Louis Steinberg of IBM for their
   experimentation.

9.  Security Considerations

   There is one management object defined in this MIB that has a MAX-
   ACCESS clause of read-write.  That object, dot3PauseAdminMode, may be
   used to change the flow control configuration on a network interface,
   which may result in dropped packets, or sending flow control packets
   on links where the link partner will not understand them.  Either
   action could be detrimental to network performance.

   Such objects may be considered sensitive or vulnerable in some
   network environments.  The support for SET operations in a non-secure
   environment without proper protection can have a negative effect on
   network operations.

   Some of the readable objects in this MIB module (i.e., objects with a
   MAX-ACCESS other than not-accessible) may be considered sensitive or
   vulnerable in some network environments.  In particular, the
   dot3StatsEtherChipSet object may be considered sensitive in many
   environments, since it would allow an intruder to obtain information
   about which vendor's equipment is in use on the network.  Note that
   this object has been deprecated.  However, some implementors may
   still choose to implement it for backwards compatability.

   Most of the objects in this MIB module contain statistical
   information about particular network links.  In some network
   environments, this information may be considered sensitive.

Top      Up      ToC       Page 60 
   It is thus important to control even GET and/or NOTIFY access to
   these objects and possibly to even encrypt the values of these
   objects when sending them over the network via SNMP.

   SNMP versions prior to SNMPv3 did not include adequate security.
   Even if the network itself is secure (for example by using IPSec),
   even then, there is no control as to who on the secure network is
   allowed to access and GET/SET (read/change/create/delete) the objects
   in this MIB module.

   It is recommended that the implementors consider the security
   features as provided by the SNMPv3 framework (see [RFC3410], section
   8), including full support for the SNMPv3 cryptographic mechanisms
   (for authentication and privacy).

   Furthermore, deployment of SNMP versions prior to SNMPv3 is NOT
   RECOMMENDED.  Instead, it is RECOMMENDED to deploy SNMPv3 and to
   enable cryptographic security.  It is then a customer/operator
   responsibility to ensure that the SNMP entity giving access to an
   instance of this MIB module is properly configured to give access to
   the objects only to those principals (users) that have legitimate
   rights to indeed GET or SET (change/create/delete) them.

10.  IANA Considerations

   This document does not define any new name space to be administered
   by IANA.  However, section 3.2.4 does specify that some of the
   defined values in a current IANA-maintained name space are to be
   marked as deprecated or obsolete.  In particular, the following
   enumerated values in the IANAifType TEXTUAL-CONVENTION in the
   IANAifType-MIB module have had an ASN.1 comment added by IANA stating
   that they have been deprecated:

       - iso88032Csmacd(7)
       - starLan(11)

   In addition, the following enumerated values have had an ASN.1
   comment added by IANA stating that they are obsolete:

       - fastEther(62)
       - fastEtherFX(69)
       - gigabitEthernet(117)

   In all of the above cases, the ASN.1 comment indicates that
   ethernetCsmacd(6) should be used instead of these values.

      (5)   The following objects have been added for management
            of the Rate Control function in WAN applications of
            ethernet:  dot3StatsRateControlAbility and
            dot3StatsRateControlStatus.

      (6)   The following 64-bit counters have been added to
            support operation on high-speed ethernet interfaces:
            dot3HCControlInUnknownOpcodes, dot3HCInPauseFrames,
            dot3HCOutPauseFrames, dot3HCStatsAlignmentErrors,
            dot3HCStatsFCSErrors, dot3HCStatsFrameTooLongs,
            dot3HCStatsInternalMacTransmitErrors,
            dot3HCStatsInternalMacReceiveErrors,
            dot3HCStatsSymbolErrors

      (7)   Object groups and compliances have been added to
            contain the new objects.

      (8)   The MODULE-IDENTITY clause has been updated to
            reflect the changes in the MIB module.

      (9)   Use of the various ifType values for ethernet has
            been clarified to emphasize that all ethernet-like
            interfaces must use the ethernetCsmacd ifType.

      (10)  Several clarifications were made to the section on
            the mapping of the Interface MIB objects to ethernet.

      (11)  MIB boilerplate in section 2 has been updated to the

   This section enumerates changes made to RFC 2358 to produce RFC 2665.

      (1)   Section 2 has been replaced with the current SNMP
            Management Framework boilerplate.

      (2)   The ifMtu mapping has been clarified.

      (3)   The relationship between the IEEE 802.3 octet counters
            and the IF-MIB octet counters has been clarified.

      (4)   REFERENCE clauses have been updated to reflect the
            actual IEEE 802.3 managed object that each MIB object
            is based on.

      (5)   The following object DESCRIPTION clauses have been
            updated to reflect that they do not increment in
            full-duplex mode: dot3StatsSingleCollisionFrames,
            dot3StatsMultipleCollisionFrames, dot3StatsSQETestErrors,
            dot3StatsDeferredTransmissions, dot3StatsLateCollisions,
            dot3StatsExcessiveCollisions, dot3StatsCarrierSenseErrors,
            dot3CollFrequencies.

      (6)   The following object DESCRIPTION clauses have been
            updated to reflect behaviour on full-duplex and
            1000 Mb/s interfaces: dot3StatsAlignmentErrors,
            dot3StatsFCSErrors, dot3StatsSQETestErrors,
            dot3StatsLateCollisions, dot3StatsSymbolErrors.
