Overview + + This memo is a revision of RFC 1095 - "The Common Management + Information Services and Protocol over TCP/IP" [27]. It defines a + network management architecture that uses the International + Organization for Standardization's (ISO) Common Management + Information Services/Common Management Information Protocol + (CMIS/CMIP) in the Internet. This architecture provides a means by + which control and monitoring information can be exchanged between a + manager and a remote network element. In particular, this memo + defines the means for implementing the International Standard (IS) + version of CMIS/CMIP on top of both IP-based and OSI-based Internet + transport protocols for the purpose of carrying management + information defined in the Internet-standard management information + base. Together with the relevant ISO standards and the companion + RFCs that describe the initial structure of management information + and management information base, these documents provide the basis + for a comprehensive architecture and system for managing both IP- + based and OSI-based internets, and in particular the Internet. + + In creating this revision of RFC 1095, the following technical and + editorial changes were made: + + 1) The tutorial section on OSI Management included in RFC 1095 + has been removed from this document. After some revisions, + the tutorial material may be published as another RFC. + + 2) The sections in RFC 1095 which discussed the semantics of how + to interpret requests in the context of Internet MIBs has been + removed from this protocol document. This topic is now + discussed in the OIM-MIB-II draft document. This protocol + should be useable with MIB-I or MIB-II. But, it will also be + able to exploit the new features of the OIM-MIB-II. + + 3) This document is based on the final International Standards + for CMIS/CMIP (ISO 9595/9596) rather than the Draft + International Standards. + + 4) Many of the original agreements defined in RFC 1095 have been + accepted and included in the OIW NMSIG implementers agreements. + Rather than duplicating these agreements, they have been removed + from this memo. This document should be read in conjunction + with ISO 9595/9596 (CMIS/CMIP) and the OIW Stable Agreements + document. + + 5) The Association Negotiation describe in RFC 1095 has been + changed to align with current international and national + agreements. But, it has retained backwards compatibility with + + + +Warrier, Besaw, LaBarre & Handspicker [Page 2] + +RFC 1189 CMOT and CMIP October 1990 + + + the assignment of an Application Context Name which is identical + to the Application Context Name specified in RFC 1095. + +2. Introduction + + This memo is the output of the OSI Internet Management Working Group + of the Internet Engineering Task Force (IETF). As directed by the + Internet Activites Board (IAB) in RFC 1052, it addresses the need for + a long-term network management system based on ISO CMIS/CMIP. This + memo contains a set of protocol agreements for implementing a network + management system based on these ISO Management standards. Now that + CMIS/CMIP has been voted an International Standard (IS), it has + become a stable basis for product development. This profile + specifies how to apply CMIP to management of both IP-based and OSI- + based Internet networks. Network management using ISO CMIP to manage + IP-based networks will be refered to as "CMIP Over TCP/IP" (CMOT). + Network management using ISO CMIP to manage OSI-based networks will + be refered to as "CMIP". This memo specifies the protocol agreements + necessary to implement CMIP and accompanying ISO protocols over OSI, + TCP and UDP transport protocols. + + This memo must be read in conjunction with ISO and Internet documents + defining specific protocol standards. Documents defining the + following ISO standards are required for the implementor: Abstract + Syntax Notation One (ASN.1) [5, 6], Association Control (ACSE) [7, + 8], Remote Operations (ROSE) [9, 10], Common Management Information + Services (CMIS) [11] and Common Management Information Protocol + (CMIP) [12] with their addenda [32-35]. The specification of a + lightweight presentation layer protocol is required for use with the + CMOT section of this profile (see RFC 1085 [13]). The SMI (see RFC + 1065 [2]), the MIB-I (see RFC 1066 [3]), the MIB-II (see RFC 1156 + [28]), and the OIM-MIB-II (see [29]) are used with this management + system. + + This memo is divided into sections for each of the protocols for + which implementors' agreements are needed: CMISE, ACSE, ROSE, and, + for CMOT, the lightweight presentation protocol. The protocol + profile defined in this memo draws on the technical work of the OSI + Network Management Forum [14] and the Network Management Special + Interest Group (NMSIG) of the National Institute of Standards and + Technology (NIST) (formerly the National Bureau of Standards) [30]. + Wherever possible, an attempt has been made to either directly + reference or remain consistent with the protocol agreements reached + by these groups. + + + + + + + +Warrier, Besaw, LaBarre & Handspicker [Page 3] + +RFC 1189 CMOT and CMIP October 1990 + + +3. Protocol Overview + + This part of the document is a specification of the protocols of the + OIM architecture. Contained herein are the agreements required to + implement interoperable network management systems using these + protocols. The protocol suite defined by these implementors' + agreements will facilitate communication between equipment of + different vendors, suppliers, and networks. This will allow the + emergence of powerful multivendor network management based on ISO + models and protocols. + + The choice of a set of protocol standards together with further + agreements needed to implement those standards is commonly referred + to as a "profile." The selection policy for this profile is to use + existing standards from the international standards community (ISO + and CCITT) and the Internet community. Existing ISO standards and + draft standards in the area of OSI network management form the basis + of this profile. Other ISO application layer standards (ROSE and + ACSE) are used to support the ISO management protocol (CMIP). To + ensure interoperability, certain choices and restrictions are made + here concerning various options and parameters provided by these + standards. Internet standards are used to provide the underlying + network transport. These agreements provide a precise statement of + the implementation choices made for implementing ISO network + management standards in IP-based and OSI-based internets. + + In addition to the OIM working group, there are at least two other + bodies actively engaged in defining profiles for interoperable OSI + network management: the OSI Implementors Workshop (OIW) and the OSI + Network Management Forum. Both of these groups are similar to the + OIM working group in that they are each defining profiles for using + ISO standards for network management. Both differ in that they are + specifying the use only of underlying ISO protocols, while the OIM + working group is concerned with using OSI management in both OSI and + TCP/IP networks. In the interest of greater future compatibility, + the OIM working group has attempted to make this profile conform as + closely as possible to the ongoing work of these two bodies. + + This section will describe the CMOT Protocol Suite, the CMIP Protocol + Suite and Conformance Requirements common to both CMOT and CMIP. + Later sections will specify the implementers agreements for specific + layer protocols that comprise the CMOT and CMIP Protocol Suites. + + + + + + + + + +Warrier, Besaw, LaBarre & Handspicker [Page 4] + +RFC 1189 CMOT and CMIP October 1990 + + +3.1. The CMOT Protocol Suite + + The following seven protocols compose the CMOT protocol suite: ISO + ACSE, ISO DIS ROSE, ISO CMIP, the lightweight presentation protocol + (LPP), UDP, TCP, and IP.

A CMOT-conformant system must support + the use of the LPP over either UDP or TCP. The use of the LPP over + both UDP and TCP on the same system may be supported. + + A CMIP-conformant system must implement the following protocols: + ACSE, ROSE, CMIP, ISO Presentation, ISO Session and ISO Transport. + + + + +Warrier, Besaw, LaBarre & Handspicker [Page 6] + +RFC 1189 CMOT and CMIP October 1990 + + +4. Common Management Information Service Element + + The Common Management Information Service Element (CMISE) is + specified in two ISO documents. The service definition for the + Common Management Information Service (CMIS) is given in ISO 9595 + [11]. The protocol specification for the Common Management + Information Protocol (CMIP) is found in ISO 9596 [12]. In addition, + the addenda for add/remove support in M-SET [32, 34] must be + supported for both CMOT and CMIP. The addenda for M-CANCEL-GET [33, + 35] may be supported by an implementation, but it's use is negotiated + as part of association negotiation. + +4.1. Association Policies + + The following ACSE services are required by CMISE: A-ASSOCIATE, A- + RELEASE, A-ABORT, and A-P-ABORT. The rest of the CMIP protocol uses + the RO-INVOKE, RO-RESULT, RO-ERROR, and RO-REJECT services of ROSE. + + There are four types of association that may be negotiated between + managing and managed systems. These types are: + + Event M-EVENT-REPORTs may be sent by the + managed system; no other CMIP PDUs + are allowed + + Event/Monitor same as Event type except that, in + addition, the managing system may + also issue M-GET requests and + receive M-GET responses over the + association + + Monitor/Control managing system may issue M-GET, + M-SET, M-CREATE, M-DELETE and + M-ACTION requests over the + association; no event reporting is + allowed + + Full Mgr/Agent all functions must be supported + + A conformant system must support at least one of these Association + types. Note that a system may play both managing and managed system + roles, but not on the same association. + + The negotiation process uses the A-ASSOCIATE and A-RELEASE services. + Application Context Name is used to determine the requestor's "role" + in an association (as managing or managed system) and to determine + the type of the association. + + + + +Warrier, Besaw, LaBarre & Handspicker [Page 7] + +RFC 1189 CMOT and CMIP October 1990 + + + The following values for Application Context Name are registered for + for CMOT and CMIP: + + {iso(1) identified-organization(3) dod(6) + internet(1) mgmt(2) mib(1) oim(9) acn(1) + cmot1095(1)} + (for backwards compatible negotiation with RFC 1095 CMOT + implementations) + + {iso(1) identified-organization(3) dod(6) + internet(1) mgmt(2) mib(1) oim(9) acn(1) + manager-event-association(2)} + + {iso(1) identified-organization(3) dod(6) + internet(1) mgmt(2) mib(1) oim(9) acn(1) + manager-event-monitor-association(3)} + + {iso(1) identified-organization(3) dod(6) + internet(1) mgmt(2) mib(1) oim(9) acn(1) + manager-monitor-control-association(4)} + + {iso(1) identified-organization(3) dod(6) + internet(1) mgmt(2) mib(1) oim(9) acn(1) + manager-full-association(5)} + + {iso(1) identified-organization(3) dod(6) + internet(1) mgmt(2) mib(1) oim(9) acn(1) + agent-event-association(6)} + + The following negotiation rules are to be used: + + 1. A managed system may only request an Event + association and, in fact, must create an Event + association if it has an event to report and no + suitable association already exists. + + 2. Managing systems may request any association type. + + 3. An association is created by the requesting system + issuing an A-ASSOCIATE request with the + requestor's AE-TITLE and the desired application + context. The responding system then returns + either 1) an A-ASSOCIATE response with the + requestor's AE-TITLE and the application context + which it wishes to accept or 2) an A-ASSOCIATE + response rejecting the association. + + + + + +Warrier, Besaw, LaBarre & Handspicker [Page 8] + +RFC 1189 CMOT and CMIP October 1990 + + + 4. Managed systems may negotiate "downward" from + Full to Monitor/Control, Event/Monitor or Event by + returning the new application context in the + A-ASSOCIATE response to the managing system during + the association creation process. In the same + fashion, managed systems may negotiate from + Event/Monitor to Event. + + 5. When a managing system receives an application + context in an A-ASSOCIATE response that differs + from the context sent in an A-ASSOCIATE request it + may either proceed with the new context or refuse + the new context by issuing an A-RELEASE request. + + A-RELEASE is used when the requestor does not agree with the new + context. A-ABORT is used for invalid negotiation. If A-ABORT were + to be used to terminate an association, there exists the potential + for loss of information, such as pending events or confirmations. + A-ABORT must be used, however, when a protocol violation occurs or + where an association is not yet established. + +4.2. CMIS Services + +4.2.1 General Agreements on Users of CMIS + + The general agreements on users of CMIS shall be as specified in the + OIW Stable Agreements [30] section 18.6.2. + + The following additional agreements are specified. + + o A system need only implement the services and service + primitives required for the association types (section 4.1) + that it supports. + + o Current/Event times shall be fields shall use 1 millisecond + granularity. If the system generating the PDU does not have + the current time, yet does have the time since last boot, then + GeneralizedTime can be used to encode this information. The + time since last boot will be added to the base time "0001 + Jan 1 00:00:00.00" using the Gregorian calendar algorithm. + (In the Gregorian calendar, all years have 365 days except + those divisible by 4 and not by 400, which have 366.) The use + of the year 1 as the base year will prevent any confusion + with current time. + + If no meaningful time is available, then the year 0 shall be + used in GeneralizedTime to indicate this fact. + + + + +Warrier, Besaw, LaBarre & Handspicker [Page 9] + +RFC 1189 CMOT and CMIP October 1990 + + +4.2.2 Specific Agreements on Users of CMIS + + The specific agreements on users of CMIS shall be as specified in the + OIW Stable Agreements [30] section 18.6.3. + + The following additional agreements are specified: + + o Event time shall be mandatory for all events. + + o Both the "managed Object Class" and "managed Object + Instance" parameters must be present in the following CMIS + Service Response/Confirmation primitives: the + M-EVENT-REPORT Confirmed, the M-GET, the M-SET, the + M-ACTION, the M-CREATE, and the M-DELETE. + +4.3. CMIP Agreements + + The CMIS and CMIP implementers agreements documented in the OIW + Stable Implementers Agreements [30] plus those mandated by the CMIP + standard will be used for both CMOT and CMIP. In addition to these + implementers agreements, the following specific agreements must be + observed: + + o An implementation is required to support all filter items + except subsetOf, supersetOf, nonNullSetIntersection, and + substrings. + + o The "managedObjectInstance" field must be present in the + ProcessingFailure Error PDU. The "managedObjectClass" + field must be present in the NoSuchArgument Error PDU. + + + [Temporary Note: The CMIS/P implementers agreements have reach a + fairly stable status in the OIW working agreements document. It is + expected that the CMIS/P agreements (18.6.2 and 18.6.3) will be + recommended to be moved into the stable agreements document during + either the June 1990 meetings. Reference [30] points to the presumed + June 1990 updated version of the stable agreements document.] + +5. Services Required by CMIP + + The services required by CMIP shall be as specified in the OIW Stable + Implementors Agreements [30] section 18.6.5. + + The following additional agreements are specified: + + o ASCE Requirements: Application contexts shall be as defined + in section 4.1 of these agreements. The values and defaults + + + +Warrier, Besaw, LaBarre & Handspicker [Page 10] + +RFC 1189 CMOT and CMIP October 1990 + + + of parameters to the ACSE parameters given to the presentation + service are specified in RFC 1085 [13] for CMOT and in the NIST + Stable Implementers Agreements [30] for CMIP. + + o Presentation Requirements: CMOT implementations shall be + supported by the Lightweight Presentation Protocol (LPP) + [13]. The LPP may use either TCP or UDP. When UDP is used, + an implementation need not accept LPP PDUs whose length + exceeds 484 octets. + + o Session Requirements: CMOT implementations will not + require the session protocol. + +6.
