1.  The Internet-Standard Management Framework

  For a detailed overview of the documents that describe the current
  Internet-Standard Management Framework, please refer to section 7 of
  RFC 3410 [RFC3410].

  Managed objects are accessed via a virtual information store, termed
  the Management Information Base or MIB.  MIB objects are generally
  accessed through the Simple Network Management Protocol (SNMP).
  Objects in the MIB are defined using the mechanisms defined in the
  Structure of Management Information (SMI).  This memo specifies a MIB
  module that is compliant to the SMIv2, which is described in STD 58,
  RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
  [RFC2580].






Lam, et al.                 Standards Track                     [Page 2]

RFC 3591               Optical Interface Type MIB         September 2003


2.  Overview

  In this document, the term OTN (Optical Transport Network) system is
  used to describe devices that are compliant with the requirements
  specified in the ITU-T Recommendations G.872 [ITU-T G.872], G.709
  [ITU-T G.709], G.798 [ITU-T G.798], G.874 [ITU-T G.874], and G.874.1
  [ITU-T G.874.1].

  The optical objects will be managed using the MIB II ifTable and
  ifStackTable.  Additional tables will also be supported to monitor
  layer specific status and provide performance monitoring data.  In
  the tables, some entries are required for OTN systems only.  A
  Configuration (Config) table, Current Performance Monitoring (PM)
  table, and Interval PM table will be maintained for the OTSn, OMSn,
  OChGroup, and OCh layers on a source and sink trail termination
  basis.  These tables will be linked to the ifTable by using the
  ifIndex that is associated with that layer.

  These objects are used when the particular media being used to
  realize an interface is an Optical Transport interface.  At present,
  this applies to these values of the ifType variable in the Internet-
  standard MIB:

  opticalChannel (195), opticalChannelGroup (219), opticalTransport
  (196)

  The definitions contained herein are based on the OTN specifications
  in ITU-T G.872[ITU-T G.872], G.709 [ITU-T G.709], G.798[ITU-T G.798],
  G.874[ITU-T G.874], and G.874.1 [ITU-T G.874.1].

2.1.  Use of the ifTable

  This section specifies how the MIB II interfaces group, as defined in
  RFC 2863 [RFC2863], is used for optical interfaces.  Only the
  ifGeneralInformationGroup will be supported for the ifTable and the
  ifStackTable to maintain the relationship between the various layers.
  The OTN layers are managed in the ifTable using IfEntries that
  correlate to the layers depicted in Figure 1.

  For example, a DWDM device with an Optical Network Node Interface
  (ONNI) will have an Optical Transmission Section (OTS) physical
  layer, an Optical Multiplex Section (OMS) layer (transports multiple
  optical channels), and an Optical Channel (OCh) layer.  There is a
  one to one relationship between the OMS and OTS layers.  The OMS
  layer has fixed connectivity via the OTS and thus no connectivity
  flexibility at the OMS layer is supported.





Lam, et al.                 Standards Track                     [Page 3]

RFC 3591               Optical Interface Type MIB         September 2003


  A device with an ONNI that does not multiplex would consist of the
  OTS and OCh layers supporting a single channel.

  MIB-II (RFC 1213) [RFC1213], as amended and extended by RFC 3418
  [RFC3418], RFC 2863 [RFC2863], and RFC 2864 [RFC2864], accommodates
  these cases through appropriate use of the system and interfaces
  groups.  The system group names and describes the type of managed
  resource.  The interfaces group defines which OTN layers exist and
  how these layers are configured and multiplexed.  This is achieved by
  proper representation of OTN Layers as IfEntries as defined in RFC
  2863 [RFC2863], as follows.

  In the following figures, opticalChannel and opticalTransport are
  abbreviated as och and otn respectively.

                        Figure 1: OTN Layers

  Since the OMSn and OTSn layers have a one to one relationship, only
  one otn IfEntry is required to support these two layers.  Therefore,
  each opticalChannel IfEntry may be mapped to m opticalTransport
  IfEntries, where m is greater than or equal to 1.  Conversely, each
  opticalTransport entry may be mapped to n opticalChannel IfEntries,
  where n is greater than or equal to 1.

  There are implementations that have banded amplifers that operate on
  a group of optical channels separately (e.g., C and L band channels)
  before finally muxing them together and transporting them over a

  physical layer.  For such DWDM system implementations, it is
  important to have the ability to model each of the groups (or bands)
  with an ifIndex and measure the pre-OTN PM parameters for each band
  separately.

  The OTN layering, as described in Figure 1, can be extended to
  accomodate such implementations by introducing another layer called
  the OChGroup Layer.

  As an example, Figure 2 depicts the OTN layering of a DWDM system
  with 80 C-band and 80 L-band channels combined into their respective
  channel band groups before being muxed into the OMS and transported
  over the OTS.

            Figure 2: OTN Layers for a Banded Configuration

  If an implementation does not wish to model the banded configuration,
  the OChGroup layer is absent and the OTN layering model degenerates
  to the description in Figure 1.  In other words, when there is an
  amplifier that covers the whole band, the optIfOMSn objects should be
  used, rather than using the optIfOChGroup objects with a degenerate
  group that covers all channels.

  The design of the Optical Interface MIB provides the option to model
  an interface either as a single bidirectional object containing both
  sink and source functions or as a pair of unidirectional objects, one
  containing sink functions and the other containing source functions.



Lam, et al.                 Standards Track                     [Page 5]

RFC 3591               Optical Interface Type MIB         September 2003


  If the sink and source for a given protocol layer are to be modelled
  as separate objects, then there need to be two ifTable entries, one
  that corresponds to the sink and one that corresponds to the source,
  where the directionality information is provided in the configuration
  tables for that layer via the xxxDirectionality objects.  The agent
  is expected to maintain consistent directionality values between
  ifStackTable layers (e.g., a sink must not be stacked in a 1:1 manner
  on top of a source, or vice-versa), and all protocol layers that are
  represented by a given ifTable entry are expected to have the same
  directionality (i.e., instances of optIfOTSnDirectionality and
  optIfOMSnDirectionality that correspond to a given ifIndex value must
  have the same value, and instances of optIfOChDirectionality,
  optIfOTUkDirectionality, and optIfODUkDirectionality that correspond
  to a given ifIndex value must have the same value).

  When separate ifTable entries are used for the source and sink
  functions of a given physical interface, association between the two
  uni-directional ifTable entries (one for the source function and the
  other for the sink functions) should be provided.  It is recommended
  that identical ifName values are used for the two ifTable entries to
  indicate such association.  An implementation shall explicitly state
  what mechanism is used to indicate the association, if ifName is not
  used.

  Example 1: Management of unterminated opticalChannel (och) using
             passive optics

     An OTN device connected with two adjacent nodes in a single fiber
     ring that supports 10 wavelengths per fiber would have 2
     opticalTransport IfEntries and 20 opticalChannel IfEntries, as
     depicted in Figure 3.  Thus 10 opticalChannel IfEntries are
     stacked above the first opticalTransport IfEntry, and the other 10
     opticalChannel IfEntries are stacked above the second
     opticalTransport IfEntry.  Note that the optical channels in this
     example are un-terminated, and thus no OTUk objects will be
     instantiated for these optical channels.  The opticalChannel
     IfEntries of one otn may be dropped/added from/to the OTN device
     or cross-connected with the opticalChannel IfEntries of the other
     otn.  Cross-connection from a member of the first 10
     opticalChannel IfEntries to a member of the second 10
     opticalChannel IfEntries could be modelled by using a cross-
     connect object, which is not yet defined in this version of the
     MIB.

2.5.  Use of ifStackTable

  Use of the ifStackTable and ifInvStackTable to associate the
  opticalTransport and opticalChannel interface entries is best
  illustrated by the example shown in Figure 5.  The example assumes an
  otn interface with ifIndex i that carries two multiplexed och
  interfaces with ifIndex values of j and k, respectively.  The example
  shows that j and k are stacked above (i.e., multiplexed into) i.
  Furthermore, it shows that there is no layer lower than i and no
  layer higher than j and/or k.

                    HigherLayer   LowerLayer
                   --------------------------
                        0             j
                        0             k
                        j             i
                        k             i
                        i             0

             Figure 5: Use of ifStackTable for an OTN port

  Figure 6 illustrates an example for a banded configuration.  The
  example assumes an otn interface with ifIndex i that carries two
  multiplexed och groups with ifIndex values u and v.  An och group
  with ifIndex value u combines two och interfaces with ifIndex values
  of a and b.  An och group with ifIndex value v combines two och
  interfaces with ifIndex values of c and d.  The example show that a
  and b are stacked above (i.e., multiplexed into) u.  Likewise, c and
  d are stacked above v.  u and v are multiplexed into i.  Furthermore,
  it shows that there is no layer lower than i and no layer higher than
  a, b, c, and/or d.  It also shows that u has a and b as its higher
  layers, and v has c and d as its higher layers.

                    HigherLayer   LowerLayer
                   --------------------------
                        0             a
                        0             b
                        0             c
                        0             d
                        a             u
                        b             u
                        c             v
                        d             v
                        u             i

  For the inverse stack table, it provides the same information as the
  interface stack table, with the order of the Higher and Lower layer
  interfaces reversed.

2.6.  Optical Network Terminology

  The terminology used in this document to describe the layers of an
  optical network and the error conditions and performance monitoring
  parameters on an optical circuit as monitored by an optical system is
  listed below.  These terms are defined in ITU-T Recommendations G.872
  [ITU-T G.872], G.709 [ITU-T G.709], G.798 [ITU-T G.798], G.874 [ITU-T
  G.874], G.874.1 [ITU-T G.874.1], and G.806 [ITU-T G.806].  Brief
  definitions of some terms are also included here to facilitate the
  readability of this document.

  Degraded Threshold (DEGTHR) - G.806
        A threshold level for declaring a performance monitoring (PM)
        Second (a time period of one second) to be bad.  A PM Second is

        that second or the number of errored blocks in that Second is
        greater than or equal to DEGTHR.

  DEGM - G.806
        A threshold level for declaring a Degraded Signal defect
        (dDEG).  A dDEG shall be declared if DEGM consecutive bad PM
        Seconds are detected.

        The Expected Destination Access Point Identifier (ExDAPI),
        provisioned by the managing system, to be compared with the TTI
        accepted at the overhead position of the sink for the purpose
        of checking the integrity of connectivity.

  Optical Channel Layer Network (OCh) - G.872
        This layer network provides end-to-end networking of optical
        channels for transparently conveying client information of
        varying format (e.g., SDH STM-N, PDH 565 Mbit/s, cell based
        ATM, etc.).

  Optical Channel Data Unit Path Layer Network (ODUk) - G.709/Y.1331
        This layer network provides functionality for the transport of
        information structure consisting of the information payload
        (OPUk) and the related overhead for management of an optical
        channel.

  Optical Channel Data Unit Tandem Connection Sub-Layer Network (ODUkT)
  - G.709/Y.1331
        This layer network is a sub-layer of the optical data unit
        layer, which provides the capability for tandem connection
        monitoring.  One to six nested levels of monitoring are defined
        for OTN.

  Optical Channel Payload Unit (OPUk) - G.709/Y.1331
        The OPUk is the information structure used to adapt client
        information for transport over an optical channel.  OPUk
        capacities for k=1, k=2, k=3 are defined in ITU-T.  The index
        "k" is used to represent different versions of OPUk, ODUk and
        OTUk.  k=1 represents an approximate bit rate of 2.5 Gbit/s,
        k=2 represents an approximate bit rate of 10 Gbit/s, and k=3
        represents an approximate bit rate of 40 Gbit/s.

  Optical Multiplex Section Layer Network (OMS) - G.872
        This layer network provides functionality for networking of a
        multi-wavelength optical signal.  Note that a "multi-
        wavelength" signal includes the case of just one optical
        channel.

  Optical Transport Module (OTM-n[r].m) - G.872
        The OTM is the information structure that is transported across
        an ONNI.  The index n and m define the number of supported
        wavelengths and bit rates at the interface.

        Two OTM structures are defined: OTM with full functionality
        (OTM-n.m) and OTM with reduced functionality (OTM-0.m & OTM-
        nr.m).

        The OTM-n.m consists of up to n multiplexed optical channels
        and an OTM overhead signal to support the non-associated
        overhead.  The OTM-0 consists of a single optical channel





Lam, et al.                 Standards Track                    [Page 14]

RFC 3591               Optical Interface Type MIB         September 2003


        without a specific color assigned.  The OTM-nr.m consists of up
        to n multiplexed optical channels.  Non associated overhead is
        not supported.

  Optical Transport Network (OTN) - G.872
        A transport network bounded by optical channel access points.
        The optical transport network layered structure is comprised of
        the optical channel, optical multiplex section and optical
        transmission section layer networks.

        According to G.872, an OTN-compliant interface is an interface
        of the optical transport network based on the architecture
        defined in G.872, while an OTN-non-compliant interface is an
        interface that does not comply with the interface
        recommendations that will be defined for the optical transport
        network based on the architecture defined in G.872.

  Optical Transmission Section Layer Network (OTS) - G.872
        This layer network provides functionality for transmission of
        optical signals on optical media of various types.

  Optical Channel Transport Unit Section Layer Network (OTUk) - G.709
        The OTUk is the layer network that provides for the transport
        of an ODUk over one or more optical channel link connections.
        It consists of the optical channel data unit and OTUk related
        overhead (FEC and overhead for management of an optical channel
        link connection).  It is characterized by its frame structure,
        bit rate, and bandwidth.

  Payload Type Mismatch (PLM)
        The detection of a mismatch of payload type is based on a
        comparison between the expected Payload Type signal,
        provisioned via the management interface, and the received
        Payload Type signal.

  Trail Trace Identifier Transmitted (TxTI) - G.798
        The Trail Trace Identifier (TTI) information, provisioned by
        the managing system, to be placed in the TTI overhead position
        of the source of a trail for transmission.

  Trail Trace Identifier Accepted (AcTI) - G.798
        The Trail Trace Identifier (TTI) information accepted from the
        TTI overhead position at the sink of a trail.

  Trail Trace Identifier Accepted Status (AcTIStatus) - G.798
        The Status of the Trail Trace Identifier (TTI) accepted from
        the TTI overhead position at the sink of a trail.




Lam, et al.                 Standards Track                    [Page 15]

RFC 3591               Optical Interface Type MIB         September 2003


  Trace Identifier Mismatch (TIM) - G.798
        The detection of TIM is based on a comparison between the
        expected Trial Trace Identifier (TTI), configured via the
        management interface, and the received TTI.

  Trace Identifier Mismatch Consequent Action Enabled (TimActEnabled) -
  G.798
        The Consequent Action function of TIM is disabled.

  Trace Identifier Mismatch Detection Mode (TimDetMode) - G.798
        The mode of detecting Trace Identifier Mismatch (TIM).
        Possible modes are:

        (1) off - no checking,
        (2) SAPI - checking the SAPI only,
        (3) DAPI - checking  the DAPI only, and
        (4) Both - checking both the SAPI and DAPI.

2.6.1.  Defect Conditions

  The following Defect conditions are defined in G.798 (as fault cause)
  for OTN monitoring.

  ais          Alarm Indication Signal (AIS)
  bdi          Backward Defect Indication (BDI)
  bdiO         Backward Defect Indication - Overhead (BDI-O)
  bdiP         Backward Defect Indication - Payload (BDI-P)

2.6.2.  Performance Parameters

  To facilitate identification of equipment and facilities that may
  require maintenance, it is necessary to monitor parameters such as
  optical power at each layer.  The measurements are taken
  periodically, and a snapshot of the current value is also made
  available.  More specifically, performance parameters at each layer
  are maintained for the current 15-minute interval, the current 24-
  hour interval, N previous 15-minute intervals where 4 <= N <= 96, and
  one previous 24-hour interval.

  Note that some of the previous interval data will be unavailable if
  the agent has restarted within the last 24 hours.

  There is no requirement for an agent to ensure a fixed relationship
  between the start of a 15-minute or 24-hour interval and any wall
  clock;  however, some agents may align the 15-minute intervals with
  quarter hours and may align the 24-hour intervals with a particular
  hour of the day (e.g., 00:00 UTC).

  Note that some DWDM systems may also monitor the laser temperature of
  the equipment in addition to monitoring the optical power.  However,
  industry opinions vary widely with respect to laser temperature
  monitoring, in particular regarding the benefit of the monitoring and
  which temperatures are to be monitored (i.e., all or only some of the
  pump lasers).  Similarly, there are varying opinions regarding mid-
  stage power monitoring.  Since no consensus was reached, it was
  decided that the laser temperature monitoring and mid-stage
  monitoring would not be standardized in the MIB.  If an
  implementation would like to monitor these parameters, one could use
  a proprietary MIB or the ENTITY-SENSOR-MIB [RFC3433] to capture this
  information.

2.7.  Tandem Connection Monitoring (TCM)

  An ODUk termination can be provisioned to support (0..6) TCM levels.
  Each TCM field contains the following subfields:

     -  Trail Trace Identifier (TTI)
     -  Bit Interleaved Parity 8 (BIP8)
     -  Backward Defect Indication (BDI)
     -  Backward Error Indication (BEI)
     -  Status bits indicating the presence of TCM overhead, Incoming
        AlignmentError, or a maintenance signal (STAT).

  The insertion of these subfields is controlled by:

     -  optIfODUkTSourceMode or otnODUkTsinkMode

  The detection and corresponding action of these subfields are
  controlled by:

     -  optIfODUkTTimDetMode
     -  optIfODUkTTimActEnabled

  The TCM connection is used for monitoring the quality of an end to
  end connection or any segment, as illustrated in the example:

     TCM1 used for the end-to-end connection from A1 to A2.
     TCM2 used for segment B1-B2, then used again for segment B3-B4.
     TCM3-TCM6 these bytes are not in used in this example.

5.  Security Considerations

  There are a number of management objects defined in this MIB module
  with a MAX-ACCESS clause of read-write and/or read-create.  It is
  possible for writes to these objects to have disruptive effects on
  network operation that range from invalid performance data to traffic
  interruptions.  Users of this MIB module must therefore be aware that
  support for SET operations in a non-secure environment without proper
  protection can have a negative effect on network operations.  The
  most sensitive objects are the read-write and read-create objects
  listed in the optIfOtnConfigCompl compliance statement that control
  the maximum number of TCM levels allowed (optIfOTMnTcmMax), automatic
  power reduction (optIfOTSnAprControl), transmitted trail trace
  (optIfOTSnTraceIdentifierTransmitted,
  optIfOTUkTraceIdentifierTransmitted,
  optIfODUkTtpTraceIdentifierTransmitted,
  optIfODUkTTraceIdentifierTransmitted), expected source/destination
  access point identifiers (optIfOTSnDAPIExpected,
  optIfOTSnSAPIExpected, optIfOTUkDAPIExpected, optIfOTUkSAPIExpected,



Lam, et al.                 Standards Track                   [Page 167]

  optIfODUkNimDAPIExpected, optIfODUkNimSAPIExpected,
  optIfODUkTDAPIExpected, optIfODUkTSAPIExpected,
  optIfODUkTNimDAPIExpected, optIfODUkTNimSAPIExpected), trace
  identifier mismatch detection mode (optIfOTSnTIMDetMode,
  optIfOTUkTIMDetMode, optIfODUkTtpTIMDetMode, optIfODUkNimTIMDetMode,
  optIfODUkTTIMDetMode, optIfODUkTNimTIMDetMode), trace identifier
  mismatch consequent action (optIfOTSnTIMActEnabled,
  optIfOTUkTIMActEnabled, optIfODUkTtpTIMActEnabled,
  optIfODUkNimTIMActEnabled, optIfODUkTTIMActEnabled,
  optIfODUkTNimTIMActEnabled), threshold level for declaring a PM
  Second to be bad (optIfOTUkDEGThr, optIfODUkTtpDEGThr,
  optIfODUkNimDEGThr, optIfODUkTDEGThr, optIfODUkTNimDEGThr), threshold
  level for declaring a Degraded Signal defect (optIfOTUkDEGM,
  optIfODUkTtpDEGM, optIfODUkNimDEGM, optIfODUkTDEGM,
  optIfODUkTNimDEGM), whether the sink/source adaptation function is
  activated (optIfOTUkSinkAdaptActive, optIfOTUkSourceAdaptActive),
  whether Forward Error Correction is supported
  (optIfOTUkSinkFECEnabled), the application transported by the GCC
  entities (optIfGCC0Application, optIfGCC12Application), creating and
  deleting a conceptual row of a config table (optIfGCC0RowStatus,
  optIfODUkNimRowStatus, optIfGCC12RowStatus, optIfODUkTRowStatus,
  optIfODUkTNimRowStatus), whether the selected GCC overhead bytes are
  passed through or modified (optIfGCC12GCCPassThrough), TCM mode
  (optIfODUkTSinkMode), and provisioning of the sink/source LOCK signal
  (optIfODUkTSinkLockSignalAdminState,
  optIfODUkTSourceLockSignalAdminState), as these may cause traffic
  interruptions if improperly set.

  The readable objects in this MIB module (i.e., the objects with a
  MAX-ACCESS other than not-accessible) may be considered sensitive in
  some environments since, collectively, they provide information about
  the performance of interfaces in OTN equipment or networks and can
  reveal aspects of their configuration.  In such environments it is
  important to control even GET and NOTIFY access to these objects and
  possibly to 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),
  there is no control as to who on the secure network is allowed to
  access and GET/SET (read/change/create/delete) objects in this MIB
  module.

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



Lam, et al.                 Standards Track                   [Page 168]

RFC 3591               Optical Interface Type MIB         September 2003


  Further, deployment of SNMP versions prior to SNMPv3 is NOT
  RECOMMENDED.  Instead, it is RECOMMENDED that SNMPv3 be deployed and
  cryptographic security be enabled.  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.

6.  Acknowledgements

  Nathan Kohn initiated the concept, then gathered and coordinated the
  team that led to the initial version of the MIB.  Mark Stewart/Brian
  Teer wrote sections on use of interface tables, reviewed the MIB
  Object Definitions for SNMP SMIv2 compliance, and wrote the PM
  sections in working with G.7710/Y.1701.  Anni Huynh wrote the initial
  MIB definitions for the OTN interface.  Tom Rutt wrote the summary
  section on the Structure of the MIB.  Rishi Grover contributed to the
  objects to monitor banded amplifiers.  Kam Lam wrote the sections on
  Optical Networking Terminology and the OTN layers configuration
  parameters.  He was the editor for the last several versions of this
  document.

  Thanks to Maarten Vissers for providing insight into Optical
  Networking concepts.  Thanks to Lakshmi Raman and Moshe Rozenblit for
  reviewing and commenting on a preliminary version of the document.

  Special thanks to C. Mike Heard for providing a top notch doctor
  review and many helpful suggestions to improve the MIB.
