1.  Abstract

   This document defines a portion of the Management Information Base
   (MIB) for use with network management protocols in TCP/IP based
   internets.  In particular, it defines objects for managing the
   Ethernet Wide Area Network (WAN) Interface Sublayer (WIS) [P802.3ae].

   The MIB module defined in this memo is implemented in conjunction
   with the Ethernet-like Interface MIB [ETHERIF], the 802.3 Medium
   Attachment Unit MIB [MAU-MIB], the Interfaces Group MIB [RFC2863],
   and the Inverted Stack Table MIB [RFC2864].  It also extends the
   SONET MIB [RFC2558] and is implemented in conjunction with that MIB
   module.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

2.  The SNMP Management Framework

   The SNMP Management Framework presently consists of five major
   components:

    o   An overall architecture, described in RFC 2571 [RFC2571].

    o   Mechanisms for describing and naming objects and events for the
        purpose of management.  The first version of this Structure of
        Management Information (SMI) is called SMIv1 and described in
        STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
        1215 [RFC1215].  The second version, called SMIv2, is described
        in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and
        STD 58, RFC 2580 [RFC2580].

    o   Message protocols for transferring management information.  The
        first version of the SNMP message protocol is called SNMPv1 and
        described in STD 15, RFC 1157 [RFC1157].  A second version of
        the SNMP message protocol, which is not an Internet standards
        track protocol, is called SNMPv2c and described in RFC 1901
        [RFC1901] and RFC 1906 [RFC1906].  The third version of the
        message protocol is called SNMPv3 and described in RFC 1906
        [RFC1906], RFC 2572 [RFC2572] and RFC 2574 [RFC2574].

    o   Protocol operations for accessing management information.  The
        first set of protocol operations and associated PDU formats is
        described in STD 15, RFC 1157 [RFC1157].  A second set of
        protocol operations and associated PDU formats is described in
        RFC 1905 [RFC1905].

Internet Draft        <draft-ayers-wis-mib-00.txt>            10/17/2001


    o   A set of fundamental applications described in RFC 2573
        [RFC2573] and the view-based access control mechanism described
        in RFC 2575 [RFC2575].

   A more detailed introduction to the current SNMP Management Framework
   can be found in RFC 2570 [RFC2570].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB.  Objects in the MIB are
   defined using the mechanisms defined in the SMI.

   This memo specifies a MIB module that is compliant to the SMIv2.  A
   MIB conforming to the SMIv1 can be produced through the appropriate
   translations.  The resulting translated MIB must be semantically
   equivalent, except where objects or events are omitted because no
   translation is possible (use of Counter64).  Some machine readable
   information in SMIv2 will be converted into textual descriptions in
   SMIv1 during the translation process.  However, this loss of machine
   readable information is not considered to change the semantics of the
   MIB.

3.  Overview

   The objects defined in this memo are used in conjunction with objects
   defined in the Interfaces Group MIB [RFC2863], the SONET MIB
   [RFC2558], and the MAU MIB [MAU-MIB] to manage the WAN Interface
   Sublayer (WIS) defined in [P802.3ae].  The WIS contains functions to
   perform OC-192c/VC-4-64c framing and scrambling.  It resides between
   the PCS and PMA sublayers within a 10GBASE-W 10 Gb/s WAN-compatible
   PHY and may be used in conjunction with any of the PCS, PMA, and PMD
   sublayers that are defined in [P802.3ae] for 10GBASE-W PHYs.  Three
   types of 10GBASE-W PHYs are defined, distinguished by the type of
   optics employed:  10GBASE-SW, 10GBASE-LW, and 10GBASE-EW.  The
   objects defined in this memo may be used to manage an Ethernet
   interface employing any type of 10GBASE-W PHY.  They do not apply to
   any other kind of interface.  In particular, they do not apply to
   so-called Ethernet Line Terminating Equipment (ELTE) residing within
   a SONET network element that uses the 10GBASE-W PMA/PMD sublayers but
   otherwise acts as SONET Line Terminating Equipment (LTE).

   The objects presented here -- along with those incorporated by
   reference from the Interfaces Group MIB, the SONET MIB, and the MAU
   MIB -- are intended to provide exact representations of the mandatory
   attributes in the oWIS managed object class (i.e., the members of the
   pWISBasic package) defined in Clause 30 and Annex 30A of [P802.3ae].
   They are also intended to provide approximate representations of the
   optional attributes (i.e., the members of the pWISOptional package).
   Some objects with no analogues in oWIS are defined to support WIS
   testing features required by Clause 50 of [P802.3ae].

3.1.  Relationship to the SONET MIB

   Since the Ethernet WAN Interface Sublayer was designed to be SONET-
   compatible, information similar to that provided by most of the
   members of the oWIS managed object class is available from objects
   defined in the SONET MIB [RFC2558].  Thus, the MIB module defined in
   this memo is a sparse augmentation of the SONET MIB -- in other
   words, every table defined here is an extension of some table in the
   SONET MIB.  An agent implementing the objects defined in this memo
   MUST implement the objects required by the sonetCompliance2
   conformance statement in the SONET MIB, and as further detailed in
   the conformance statement in the MIB module defined in this memo.

   It should be noted that some of the objects incorporated by reference
   from the SONET MIB -- specifically, the threshold objects and
   interval counter objects -- provide only approximate representations
   of the corresponding oWIS attributes, as detailed in Section 3.6.  An
   alternative approach would have been to define new objects to exactly
   match the oWIS definitions.  That approach was rejected because the
   SONET MIB objects are already used in deployed systems to manage the
   SONET sublayers of ATM over SONET and PPP over SONET interfaces, and
   it was deemed undesirable to use a different scheme to manage the
   SONET sublayers of 10 Gb/s WAN-compatible Ethernet interfaces.  Note
   that the approach adopted by this memo requires no hardware support
   beyond that mandated by [P802.3ae] subclause 50.3.10.

3.2.  Relationship to the Ethernet-like Interfaces MIB

   An interface which includes the Ethernet WIS is, by definition, an
   Ethernet-like interface, and an agent implementing the objects
   defined in this memo MUST implement the objects required by the
   dot3Compliance2 compliance statement in the EtherLike-MIB.

3.3.  Relationship to the 802.3 MAU MIB

   Support for the mauModIfCompl2 compliance statement of the MAU-MIB
   [MAU-MIB] is REQUIRED for all Ethernet-like interfaces.  The MAU-MIB
   is needed in order to allow applications to control and/or determine
   the media type in use.  That is important for devices than can
   support both the 10GBASE-R 10 Gb/s LAN format (which does not include
   the WIS) and the 10GBASE-W 10 Gb/s WAN format (which does include the
   WIS).  The MAU-MIB also provides the means to put a device in standby
   mode or to reset it;  the latter operation is one of the actions in
   oWIS.

3.4.  Use of the ifTable

   This section specifies how the ifTable, as defined in [RFC2863], is
   used for the Ethernet WIS application.

3.4.1.  Layering Model

   Ethernet interfaces that employ the WIS are layered as defined in
   [P802.3a3].  The corresponding use of the ifTable [RFC2863] is shown
   in the figure below.

           _____________________________   _

       Figure 1 - Use of ifTable for an Ethernet WIS port

   The exact configuration and multiplexing of the layers is maintained
   in the ifStackTable [RFC2863] and in the ifInvStackTable [RFC2864].

3.4.2.  Use of ifTable for LLC Layer/MAC Layer/Reconciliation
Sublayer/Physical Coding Sublayer

   The ifTable MUST be used as specified in [ETHERIF] and [MAU-MIB] for
   the LLC Layer/MAC Layer/Reconciliation Sublayer/Physical Coding
   Sublayer.

3.4.3.  Use of ifTable for SONET/SDH Path Layer

   The ifTable MUST be used as specified in [RFC2558] for the SONET/SDH
   Path Layer.  The value of ifHighSpeed is set to 9585.  ifSpeed
   reports a value of 4294967295.

3.4.4.  Use of ifTable for SONET/SDH Medium/Section/Line Layer

   The ifTable MUST be used as specified in [RFC2558] for the SONET/SDH
   Medium/Section/Line Layer.  The value of ifHighSpeed is set to 9953.
   ifSpeed reports a value of 4294967295.

3.5.  SONET/SDH Terminology

   The SONET/SDH terminology used in [P802.3ae] is mostly the same as in
   [RFC2558], but there are a few differences.  In those cases the
   definitions in [P802.3ae] take precedence.  The specific differences
   are as follows.

   Unequipped
       This defect is not defined by [P802.3ae].  An implementation that
       supports it SHOULD report it by setting the sonetPathUnequipped
       bit in the appropriate instance of sonetPathCurrentStatus.

   Signal Label Mismatch
       This defect is called Payload Label Mismatch (PLM) in [P802.3ae].
       It is reported by setting both the sonetPathSignalLabelMismatch
       bit in the appropriate instance of sonetPathCurrentStatus
       (defined in [RFC2558]) and the etherWisPathPLM bit in the
       corresponding instance of etherWisPathCurrentStatus (defined
       below).

   Loss of Codegroup Delineation
       [P802.3ae] defines Loss of Codegroup Delineation (LCD) as
       occurring when the Physical Coding Sublayer is unable to locate
       64B/66B code group boundaries.  There is no analogous defect
       defined in [RFC2558].  It is reported by setting the
       etherWisPathLCD bit in the appropriate instance of the object
       etherWisPathCurrentStatus defined below.

   STS-Path Remote Defect Indication
       [P802.3ae] mandates the use of ERDI-P (Enhanced Remote Defect
       Indication - Path) defined in [T1.231] to signal remote server
       defects (triggered by path AIS or path LOP) and remote payload
       defects (triggered by Payload Label Mismatch or Loss of Codegroup
       Delineation).  [RFC2558] defines the one-bit RDI-P (Remote Defect
       Indication - Path), which signals remote server detects (i.e.,
       path AIS and path LOP) only.  An implementation of the WIS MUST
       set the sonetPathSTSRDI bit in the appropriate instance of
       sonetPathCurrentStatus when it receives an ERDI-P server defect
       indication from the remote end.  Both ERDI-P payload defects and
       ERDI-P server defects are reported in the object
       etherWisFarEndPathCurrentStatus defined below.

   Path Coding Violations
       In [P802.3ae] the path layer CV count is based on block errors
       and not BIP-8 errors, i.e., it is incremented only once for each
       B3 byte that indicates incorrect parity, regardless of the number
       of bits in error.  Note that Section 8.4.5.1 of [T1.231] allows
       either path BIP-8 errors or path block errors to be used for the
       path layer error count.

   Please note that despite the differences in semantics between the
   threshold objects and counter objects imported from the SONET-MIB and
   the corresponding IEEE 802.3 objects, the hardware support mandated
   by [P802.3ae] subclause 50.3.10 suffices for both.  See Appendix A
   for details.

3.7.  Mapping of SNMP Objects to WIS Station Management Registers

   Some of the objects defined in this memo or incorporated by reference
   from the SONET-MIB [RFC2558] or the MAU-MIB [MAU-MIB] require WIS-
   specific hardware support.  [P802.3ae] subclause 50.3.10 specifies
   WIS management interface requirements, including a required subset of
   the WIS MDIO (Management Data Input/Output) registers defined in
   [P802.3ae] subclause 45.2.2.  The table below provides a cross-
   reference between those managed objects and the WIS MDIO registers
   from the subset in [P802.3ae] subclause 50.3.10 required to support
   them.  Note that the MDIO interface is optional;  however, if it is
   not implemented, then the capabilities of the required register
   subset must be provided by other means.

3.8.  Structure of the MIB Module

   Four tables are defined in this MIB module.

3.8.1.  etherWisDeviceTable

   The purpose of this table is to define managed objects to control the
   WIS test pattern mode.  These objects are required to support
   mandatory WIS test features required by Clause 50 of [P802.3ae].

   The etherWisDeviceTable is a sparse augmentation of the
   sonetMediumTable of the SONET MIB -- in other words, for each entry
   in the etherWisDeviceTable there SHALL be an entry in the
   sonetMediumTable and the same ifIndex value SHALL be used for both
   entries.

3.8.2.  etherWisSectionCurrentTable

   The purpose of this table is to define managed objects for the
   transmitted and received section trace messages (J0 byte).

   The etherWisSectionCurrentTable is a sparse augmentation of the
   sonetSectionCurrentTable of the SONET MIB -- in other words, for each
   entry in the etherWisSectionCurrentTable there SHALL be an entry in
   the sonetSectionCurrentTable and the same ifIndex value SHALL be used
   for both entries.

3.8.3.  etherWisPathCurrentTable

   The purpose of this table is to define managed objects for the
   current WIS path layer status and for the transmitted and received
   path trace messages (J1 byte).  The path layer status object is
   provided because the WIS supports some near-end path status
   conditions that are not reported in sonetPathCurrentStatus.

Internet Draft        <draft-ayers-wis-mib-00.txt>            10/17/2001


   The etherWisPathCurrentTable is a sparse augmentation of the
   sonetPathCurrentTable of the SONET MIB -- in other words, for each
   entry in the etherWisPathCurrentTable there SHALL be an entry in the
   sonetPathCurrentTable and the same ifIndex value SHALL be used for
   both entries.

3.8.4.  etherWisFarEndPathCurrentTable

   The purpose of this table is to define a managed object for the
   current status of the far end of the path.  This object is provided
   because the WIS supports some far-end path status conditions that are
   not reported in sonetPathCurrentStatus.

   The etherWisFarEndPathCurrentTable is a sparse augmentation of the
   sonetFarEndPathCurrentTable of the SONET MIB -- in other words, for
   each entry in the etherWisFarEndPathCurrentTable there SHALL be an
   entry in the sonetFarEndPathCurrentTable and the same ifIndex value
   SHALL be used for both entries.

5.  Acknowledgments

   This document is a product of the WIS MIB Design Team of the the IETF
   Hubmib and AToMMIB Working Groups.  It builds upon the work of the
   IEEE P802.3ae 10 Gigabit Ethernet Task Force.

6.  Security Considerations

   There are a number of management objects defined in this MIB that
   have a MAX-ACCESS clause of read-write and/or read-create.  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.

   SNMPv1 by itself is not a secure environment.  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.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework.  Specifically, the use
   of the User-based Security Model RFC 2574 [RFC2574] and the View-
   based Access Control Model RFC 2575 [RFC2575] is recommended.

   It is then a customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, 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.

Appendix A:  Collection of Performance Data Using WIS MDIO Registers

   The purpose of this appendix is to illustrate how the WIS MDIO
   registers specified in [P802.3ae] subclause 45.2.2 (and more
   specifically the subset required by [P802.3ae] subclause 50.3.10) can
   be used to collect performance data either according to the
   conventions adopted by this document or according to the conventions
   specified in [P802.3ae] Clause 30.

   For an agent implementing the SNMP managed objects required by this
   document the first step in collecting WIS performance data would be
   to poll the 10G WIS Status 3 register and the various error count
   registers (10G WIS Section BIP Error Count, 10G WIS Line BIP Errors,
   10G WIS Far End Line BIP Errors, 10G WIS Path Block Error Count, and
   10G WIS Far End Path Block Error Count) once per second.  The 10G WIS
   Status 3 register bits are all latched until read and so would
   indicate whether a given defect occurred any time during the previous
   second.  The error count registers roll over modulo 2^16 or 2^32, and
   so to find the number of errors within the previous second the agent
   would need to subtract (modulo 2^16 or 2^32) the current reading from
   the reading taken one second ago.  Armed with that information, the
   agent could determine for any layer whether the one second interval
   was an errored second, a severely errored second (that requires
   comparison with a threshold unless a defect is present), or a
   severely errored frame second.  Determining whether a given second is
   or is not part of unavailable time requires additional logic;  the
   most straightforward and accurate method is the delay-line approach
   outlined in Appendix A of [RFC2558].  With that information available
   the agent would be able to determine by how much each current count
   should be incremented (including effects of inhibiting).
   Implementations that conform to [T1.231] would end each 15-minute
   interval on time-of-day clock 1/4 hour boundaries;  if the delay-line
   approach is used then a time-of-day timestamp would accompany the
   one-second statistics.  At the end of each interval the current
   registers would be pushed onto the history stack and then would be
   cleared.  The xyxIntervalValidData flags would be set to False(2) if
   the number of samples was not between 890 and 910 or, in the case of
   far-end counts, if a near-end defect occurred during the just-
   completed interval (see [T1.231] Section 9.1.2.2 for details).

   An agent implementing the [P802.3ae] Clause 30 oWIS objects could
   start in much the same way, i.e., by polling the 10G WIS Status 3
   register and the various error count registers to find the defects
   and error counts for the previous second, and it could determine the
   number of errors and whether the second was an errored second, a
   severely errored second, or a severely errored frame second in the
   same manner as above.  The rest of the process would be simply to
   increment the generalized non-resetable counters without
   consideration of any inhibiting rules.
