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].
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.
 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.
 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.

 Example 2: Management of terminated opticalChannel (och) interfaces
 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 4. Thus 10 opticalChannel IfEntries are
 stacked above the first opticalTransport IfEntry, and the other 10
 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.

 Figure 4: Interface stacks when channels are terminated
 Note that the two examples described above depict the interface
 stacks when the banded configuration is not modeled.
 The exact configuration and multiplexing of the layers is maintained
 in the ifStackTable (RFC 2863) [RFC2863] and in the ifInvStackTable
 (RFC 2864) [RFC2864]; see section 2.5 for details.

 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.

 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
 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
 accepted at the overhead position of the sink for the purpose
 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).
 Intra-Domain Interface (IaDI) - G.872
 A physical interface within an administrative domain.
 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
 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.
2.6.1. 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)
 deg Degraded (DEG)
 lck Locked (LCK)
 lof Loss of Frame (LOF)
 lom Loss of Multi Frame
 los Loss of Signal (LOS)
 losO Loss of Signal - Overhead (LOS-O)
 losP Loss of Signal - Payload (LOS-P)
 oci Open Connection Indication (OCI)
 plm Payload Mismatch (PLM)
 ssf Server Signal Failure (SSF)
 ssfO Server Signal Failure - Overhead (SSF-O)
 ssfP Server Signal Failure - Payload (SSF-P)
 tim Trace Identifier Mismatch (TIM)
 The relationship of these conditions within a network layer and
 between layers are described in G.798 [ITU-T G.798].
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.
 The sink-side monitoring points for the various layers are shown in
 Figure 7 below.

 Note that optical performance parameters are of type Integer32,
 rather than Counter32 or Gauge32, because it is possible for these
 objects to increase or decrease and to assume negative or positive
 values.
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.
 The TCM connection can be nested (B1-B2 is nested in A1-A2) or
 cascaded (B1-B2 and B3-B4).

 GROUP optIfOChSourcePreOtnPMThresholdGroup
 DESCRIPTION
 "This group is mandatory if and only if TCA notifications
 are implemented. If the objects of this group are instantiated
 then the implementation must also provide, in an
 enterprise MIB, suitable TCA notification definitions and
 notification control objects. Implementation of the
 optIfOChSourcePreOtnPMGroup is a prerequisite for
 implementing this group "

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,
 optIfODUkTtpDAPIExpected, optIfODUkTtpSAPIExpected,
 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).
 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.
