Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with Simple Network Management Protocol (SNMP) in TCP/IP-
   based internets.  In particular, it defines objects for managing
   Optical Interfaces associated with WavelengthDivision Multiplexing
   systems or characterized by the Optical Transport Network (OTN) in
   accordance with the OTN architecture defined in ITU-T Recommendation
   G.872.

   The MIB module defined in this memo can be used for performance
   monitoring and/or configuration of such optical interface.

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].

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.

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.

      opticalChannel IfEntries are stacked above the second
      opticalTransport IfEntry.  As the optical channels in this example
      are terminated, OTUk objects and possibly ODUk objects will be
      instantiated for the terminated opticalChannel IfEntries.

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.

   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.

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
         declared bad if the percentage of detected errored blocks in
         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.

   Expected Destination Access Point Identifier (ExDAPI) - G.798
         The Expected Destination Access Point Identifier (ExDAPI),
         provisioned by the managing system, to be compared with the TTI

         of checking the integrity of connectivity.

   Expected Source Access Point Identifier (ExSAPI) - G.798
         The Expected Source Access Point Identifier (ExSAPI),
         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.

   Inter-Domain Interface (IrDI) - G.872
         A physical interface that represents the boundary between two
         administrative domains.

         G.709 defines the requirements for the IrDI at the Network Node
         Interface (NNI).

   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

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.

   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.

2.6.2.  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.

RFC 3591               Optical Interface Type MIB         September 2003


   The TCM connection can be nested (B1-B2 is nested in A1-A2) or
   cascaded (B1-B2 and B3-B4).

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,

   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.

   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
