Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress." The list of current Internet-Drafts can be accessed at http://www.ietf.org/ietf/1id-abstracts.txt. The list of Internet-Draft Shadow Directories can be accessed at http://www.ietf.org/shadow.html. The following changes are made from "draft-stewart-atommib-opticalmib-01.txt" to align with the changes in G.798 for fault causes and fix TCM. 1) Globally: Change TimActEnabled to TimActDisabled and TimDetEnabled to TimDetDisabled to be consistent with the terms used in G.798 2) Section 3.5: Remove the entry "Top of Stack (TOP)" 3) Section 3.5.1: Remove ds, ebc, fdi, fdiO, fdiP, losc, maxTosI, tovr, tudr, and tz. Add bdiP, bdiO, tim, and lom. 4) In otnOTSnCurrentStatus, remove fdiP, fdiO, fdi, and bdi. Add bdiO and bdiP. 5) In otnOMSnCurrentStatus, remove fdiP, fdiO, fdi, and bdi. Add bdiO, bdiP and ssf. 6) In otnOChCurrentStatus, remove fdi and losc. Add losP, oci, ssfP, ssfO, and lom. 7) In the ODUkT config table, remove TopOfStack and MaxTopOfStack. Replace LockAdminState by LockAdminStateSource and LockAdminStateSink 8) In otnODUkTCurrentStatus, remove ais, cMaxTosIngress, tovr, tz, and udr. 9) Add a comment after otnODUkPCBRMapping saying that adaptation control for other client signals, such as ATM VP, is not covered in the current version of the MIB. 10) In the reference section, update the date and version of the G.872, G.709, G.798, and G.874. 11) Update the definition of TxPL and ExPL in Section 3.5. This is an editorial update that should occur even in version -00. 12) Remove otnODUkPCBRMapping from the ODUkP config table. The dedicated async and bitsync adaptation functions now in G.798 do not need Mapping provisioning anymore. Editor's note on otnODUkT Group: There are six levels of Tandem Connection sublayers. I suggest that the otnODUkTConfigTable is indexed by (ifIndex, otnODUkTId), where otnODUkTID is an Unsigned32 (1..6). Copyright Notice Copyright (C) The Internet Society (2000).

The SNMP Network Management Framework The SNMP Management Framework presently consists of five major components: 0 An overall architecture, described in RFC 2571 [RFC2571]. 0 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]. 0 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]. 0 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]. 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 (e.g., 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 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, G.709, G.798, and G.874 [ITU G.872][ITU G.709][ITU G.798][ITU G.874], available as of the date this Internet-Draft. As some of the ITU-T Recommendations have not yet been approved, implementers of DWDM systems are advised to refer to most recent versions of these ITU-T Recommendations. 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, 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), opticalTransport (196) The definitions contained herein are based on the OTN specifications in ITU-T G.872[ITU G.798], G.709 [ITU G.709], G.798[ITU G.798], and G.874[ITU G.874]. 3.1. Use of the ifTable This section specifies how the MIB II interfaces group, as defined in [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 [RFC1213], as extended by [RFC2863], accommodates these cases through appropriate use of the MIB II system and interfaces groups. The system group names and describes the type of managed resource. The interfaces group defines which OTN layers apply and how these layers are configured and multiplexed. This is achieved by proper representation of OTN Layers as IfEntries as defined in [RFC2863], as follows: In the following figures, opticalChannel and opticalTransport are abbreviated as och and otn respectively. _____________________ \ Path Data Unit |\ (ODUkP) | \ _____________________| \ ______________________ | | | > Tandem Data Unit | | | | (ODUkT) | | OCh Layer | > n och IfEntries _____________________| | | | | |______________________| > Optical | /| | > Transport Unit | / | | | (OTUk) |/ | OMSn Layer | | _____________________/ | | | |______________________| | Sub-layers in | | > m otn IfEntries the OCh Layer | | | | OTSn Layer | | | | | |______________________| > 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. 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 opticalChannel IfEntries and 10 opticalChannel IfEntries, as depicted in Figure 2. Thus, the same 10 opticalChannel IfEntries are stacked above each of the opticalTransport IfEntries. ______________________ ______________________ | | | | | | | | | och1 | ... | och10 | | och1 | ... | och10 | |_______|______|_______| |_______|______|_______| | | | | | otn1 | | otn2 | |______________________| |______________________| ____________ | | ___________________\| OTN |__________________\ /| device | / |____________| Figure 2: Interface stacks when channels are unterminated 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 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. ______________________ ______________________ | | | | | | | | | och1 | ... | och10 | | och11 | ... | och20 | |_______|______|_______| |_______|______|_______| | | | | | otn1 | | otn2 | |______________________| |______________________| ____________ | | ___________________\| OTN |__________________\ /| device | / |____________| Figure 3: Interface stacks when channels are terminated The exact configuration and multiplexing of the layers is maintained in the ifStackTable [RFC2863], see section 3.4. 3.2. Use of ifTable for OTN OTS/OMS Layer Only the ifGeneralInformationGroup needs to be supported. ifTable Object Use for combined OTN OTS/OMS Layer ===================================================================== ifIndex The interface index. ifDescr Optical Transport Network (OTN) Optical Transmission Section (OTS)/Optical Multiplex Section (OMS) ifType opticalTransport (196) ifSpeed Actual bandwidth of the interface in bits per second. If the bandwidth of the interface is greater than the maximum value of 4,294,967,295, then the maximum value is reported and ifHighSpeed must be used to report the interface's speed. ifPhysAddress An octet string with zero length. (There is no specific address associated with the interface.) ifAdminStatus The desired administrative status of the interface. Supports read-only access. ifOperStatus The operational status of the interface. The value lowerLayerDown(7) is not used, since there is no lower layer interface. This object is set to notPresent(6) if a component is missing, otherwise it is set to down(2) if either the objects otnOTSnCurrentStatus or otnOMSnCurrentStatus has any value other than noDefect(1). ifLastChange The value of sysUpTime at the last change in ifOperStatus. ifName Enterprise-specific convention (e.g., TL-1 AID) to identify the physical or data entity associated with this interface or an OCTET STRING of zero length. The enterprise-specific convention is intended to provide the means to reference one or more enterprise-specific tables. ifLinkUpDownTrapEnable Default value is enabled(1). Supports read-only access. ifHighSpeed Actual bandwidth of the interface in Mega-bits per second. A value of n represents a range of 'n-0.5' to 'n+0.499999'. ifConnectorPresent Set to true(1). ifAlias The (non-volatile) alias name for this interface as assigned by the network manager. 3.3. Use of ifTable for OTN OCh Layer Only the ifGeneralInformationGroup needs to be supported. ifTable Object Use for OTN OCh Layer ===================================================================== ifIndex The interface index. ifDescr Optical Transport Network (OTN) Optical Channel (OCh) ifType opticalChannel(195) ifSpeed Current bandwidth of the interface in bits per second. If the bandwidth of the interface is greater than the maximum value of 4,294,967,295, then the maximum value is reported and ifHighSpeed must be used to report the interface's speed. ifPhysAddress The wavelength of the optical channel, expressed in nanometers (e.g., 1550). ifAdminStatus The desired administrative status of the interface. Supports read-only access. ifOperStatus The operational status of the interface. This object is set to lowerLayerDown(7) if the ifOperStatus of its otn interface is down(2). Otherwise, it is set to down(2) if one or more of the objects otnOChCurrentStatus, otnOTUkCurrentStatus, otnODUkTCurrentStatus, and otnODUkPCurrentStatus have any value other than noDefect(1). ifLastChange The value of sysUpTime at the last change in ifOperStatus. ifName Enterprise-specific convention (e.g., TL-1 AID) to identify the physical or data entity associated with this interface or an OCTET STRING of zero length. The enterprise-specific convention is intended to provide the means to reference one or more enterprise-specific tables. ifLinkUpDownTrapEnable Default value is disabled(2). Supports read-only access. ifHighSpeed Current bandwidth of the interface in Mega-bits per second. A value of n represents a range of 'n-0.5' to 'n+0.499999'. ifConnectorPresent Set to false(2). ifAlias The (non-volatile) alias name for this interface as assigned by the network manager. 3.4. Use of ifStackTable Use of the ifStackTable to associate the opticalTransport and opticalChannel interface entries is best illustrated by the example shown in Figure 4. 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.

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 are listed below. These terms are defined in ITU-T Recommendations G.872, G.709, G.798, and G.874 [ITU G.798][ITU G.709] [ITU G.798][ITU G.874]. Brief definition of some terms are also included here to facilitate the readability of this document. 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 (ODUkP) - G.709 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 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 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 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 to 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 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 Transmitted (TxPL) The Payload Type signal of size of one byte in the OPUk overhead position of the source of a trail for transmission. TxPL is derived by the equipment from the active adaptation function. If the equipment supports multiple adaptation functions, then the adaptation function type can be provisioned by the managing system. Payload Type Received (AcPL) The Payload Type signal of size of one byte recovered (received) from the OPUk overhead position at the sink of a trail. Payload Type Expected (ExPL) The Payload Type signal of size of one byte to be compared with the payload type signal received at the OPUk overhead position of the sink for the purpose of checking the integrity of adaptation. ExPL is derived by the equipment from the active adaptation function. If the equipment supports multiple adaptation functions, then the adaptation function type can be provisioned by the managing system. Payload Type Mismatch (PLM) The detection of 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) 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 Received (AcTI) The Trail Trace Identifier (TTI) information recovered (received) from the TTI overhead position at the sink of a trail. Trail Trace Identifier Expected (ExTI) The Trail Trace Identifier (TTI) information, provisioned by the managing system, to be compared with the TTI Received at the overhead position of the sink for the purpose of checking the integrity of connectivity. Trace Identifier Mismatch (TIM) 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 Disabled (TimActDisabled) The Consequent Action function of TIM is disabled. Trace Identifier Mismatch Detection Disabled (TimDetDisabled) The function of detecting Trace Identifier Mismatch (TIM) is disabled. 3.5.1 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 loop Loss of Optical Power (LOOP) 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) 3.5.2 Performance Parameters All performance parameters are accumulated in fifteen minute intervals and up to 96 intervals (24 hours worth) are kept by an agent. Fewer than 96 intervals of data will be available if the agent has been restarted within the last 24 hours. In addition, there is a rolling 24-hour total of each performance parameter. Performance parameters continue to be collected when the interface is down. There is no requirement for an agent to ensure fixed relationship between the start of a fifteen minute interval and any wall clock; however some agents may align the fifteen minute intervals with quarter hours. Performance parameters are of types PerfCurrentCount, PerfIntervalCount and PerfTotalCount. These textual conventions are all Gauge32, and they are used because it is possible for these objects to decrease. Objects may decrease when Unavailable Seconds occurs across a fifteen minutes interval boundary. See Unavailable Seconds discussion later in this section. 4. Structure of the MIB The managed Optical Networking interface objects are arranged into the following groups of tables: The otnOTSn group handles the configuration and performance monitoring information for OTS layers. otnOTSnConfigTable otnOTSnSinkCurrentTable otnOTSnSinkIntervalTable otnOTSnSrcCurrentTable otnOTSnSrcIntervalTable The otnOMSn group handles the configuration information for OMS layers. otnOMSnConfigTable otnOMSnSinkCurrentTable otnOMSnSinkIntervalTable otnOMSnSrcCurrentTable otnOMSnSrcIntervalTable The otnOCh group handles the configuration and performance monitoring information for OCh layers. otnOchConfigTable otnOchSinkCurrentTable otnOchSinkIntervalTable otnOchSrcCurrentTable otnOchSrcIntervalTable The otnOTUk group handles configuration information for otnOTUk. otnOTUkConfigTable The otnODUkT group handles configuration information for otnODUkT. OtnODUkTConfigTable The otnODUkP group handles configuration information for otnODUkP. otnODUkPConfigTable This internet draft does not define MIB objects for optical system cross-connects. After consensus is reached on definitions of the interface MIB objects for optical systems (resulting from resolution of discussions on the objects proposed in this internet draft), work can progress on the definitions of tables to representing cross-connects (e.g., OCh optical cross-connects and ODUk electrical cross-connects). 4.1.

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. The managed objects in this MIB contain sensitive information since, collectively, they allow influencing of interfaces in OTN equipment or networks and provide information of their configuration. It is thus important to control even GET access to these objects and possibly to even encrypt the values of these object when sending them over the network via SNMP. Not all versions of SNMP provide features for such a secure environment. SNMPv1 by itself is not a secure environment. 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) 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. 7.
