Introduction This memo defines the management information base (MIB) for use with the OSI network management protocol in TCP/IP based internets. It formats the Management Information Base (MIB-II) in OSI templates and adds variables necessary for use with the OSI management protocol. Together with internet memos that define agreements for using the OSI management protocol to manage TCP/IP internets (RFC 1189) [3], the management information base: MIB-II, and OSI standards defining the structure of management information (ISO/IEC DIS 10165) [4,5,6], these documents provide an OSI compatible architecture and system for managing TCP/IP based internets and in particular the Internet community. This OSI version of the MIB specification is an incremental refinement of MIB-II. It has been designed according to the following policy: first, maintain compatibility with MIB-II by including objects in MIB-II without changes to their registered identifiers, syntax, and behaviour; second, format the MIB-II using the OSI structure of information defined templates; third, add attributes necessary for identification using the OSI management protocol; fourth, identify object instances in a manner which is compatible with development of a common application programming interface for both CMIP and SNMP; and finally, define notifications (events), including those defined by SNMP (RFC 1157) [14], deemed necessary for management. It is expected that the MIB will grow over time to accommodate the changing needs of the Internet. As reported in RFC 1109, Report of the Second Ad Hoc Network Management Review Group [13], the requirements for SNMP and OSI frameworks were more different than anticipated. Therefore, the requirement for compatibility between the SMI/MIB for both frameworks was suspended. This action allowed both frameworks to independently define the MIB according to their SMI requirements and views of management. The SNMP response included development of MIB-II. The OSI response is this document which builds on the excellent work done in MIB-II, and adds to it attributes necessary to map into the OSI OIM Working Group [Page 2] RFC 1214 MIB-II-OIM April 1991 SMI. The OIM network management framework consists of: Open Systems Interconnection - Structure of Management Information: Parts 1-4, ISO/IEC DIS 10165 [4,5,6], with slight modifications to maintain compatibility with RFC 1155 [11]; OSI Internet Management: Management Information Base, this memo; and the OSI Common Management Information Service (CMIS) [7] and Common Management Information Protocol (CMIP) [8]. 2. Additions to MIB-II Additions to MIB-II fall into the following categories: the addition of the managed object class "top" from which all object classes are derived; additions for object instance identification purposes according to the OSI SMI; additions for generation of asynchronous events; the addition of name bindings which define the binding between objects in the containment (naming) hierarchy; and the addition of proposed changes to RFC 1158 that are expected to be accepted by the IETF [16]. 2.1 Structure of the OIM Subtree The oim subtree structure is defined below. Note that the "cmot" subtree has been relabeled to "oim". cmot OBJECT IDENTIFIER ::= {mib 9} oim OBJECT IDENTIFIER ::= {cmot} cmotVersion OBJECT IDENTIFIER ::= {oim 1} cmotACSEInfo OBJECT IDENTIFIER ::= {oim 2} cmotSystemId OBJECT IDENTIFIER ::= {oim 3} misc OBJECT IDENTIFIER ::= {oim 4} objects OBJECT IDENTIFIER ::= {oim 5} attributes OBJECT IDENTIFIER ::= {oim 6} events OBJECT IDENTIFIER ::= {oim 7} nameforms OBJECT IDENTIFIER ::= {oim 8} actions OBJECT IDENTIFIER ::= {oim 9} 2.2 Supporting ISO Definitions The OSI defined managed object class "top" [5], as defined by OSI, has been added to the MIB. This managed object class is the root of the inheritance hierarchy. The class "top" contains attributes that are inherited by all objects in the MIB. Pending the progression of ISO/IEC DIS 10165 to an International Standard status, "top" and its associated attributes are registered in Appendix 3. OIM Working Group [Page 3] RFC 1214 MIB-II-OIM April 1991 2.3 Additions for Object Instance Identification The conventions for identifying objects in the OIM MIB-II for use with CMIP are defined below. 2.3.1 Distinguished Names The distinguished name of an object shall consist of a sequence of relative distinguished names, one for each object on the containment path from the root to the object. Each relative distinguished name shall contain exactly one attribute, the "naming" attribute for the corresponding class, as specified by a NAME BINDING template. The CMIP ObjectInstance shall be encoded using the distinguishedName choice. Object classes for which there is only a single instance normally implemented in a managed system, other than the "system" managed object class, shall use an empty string for their naming attribute value, i.e., a string of length zero. The format of the naming attribute for the "system" managed object class and object classes which normally have multiple instances, e.g., table entries, are defined in the attribute templates for the naming attributes of those classes. The formats for naming attributes of table entries are compatible with instance identification conventions used by SNMP, thereby facilitating the development of a common application programming interface that may interface to either protocol. For example, a distinguished name designating a particular routing table entry (of class ipRouteEntry) might be { { sysName = "troi.mitre.org"} { ipId = ""} { ipRoutingTableId = "" } { ipRouteEntryId = "129.83.2.17" } }. The naming attributes for each OIM MIB-II managed object class listed in section 5 may be determined by reference to the NAME BINDING templates listed in section 8. The naming attribute definitions can be found in the alphabetical listing of all attributes in section 6. The following attributes have been defined for MIB-II object classes for purposes of object instance identification. OIM Working Group [Page 4] RFC 1214 MIB-II-OIM April 1991 Attribute Identifier Object ifTableId {attributes 1} ifTable atTableId {attributes 2} atTable atEntryId {attributes 3} atEntry ipId {attributes 4} ip ipAddrTableId {attributes 5} ipAddrTable ipRoutingTableId {attributes 6} ipRoutingtable ipNetToMediaTableId {attributes 7} ipNetToMediaTable ipNetToMediaEntryId (attributes 8} ipNetToMediaEntry icmpId {attributes 9} icmp tcpId {attributes 10} tcp tcpConnTableId {attributes 11} tcpConnTable tcpConnId {attributes 12} tcpConnEntry udpId {attributes 13} udp udpTable udpEntryId {attributes 15} udpEntry egpId {attributes 16} egp egpNeighTableId {attributes 17} egpneighTable snmpId {attributes 18} snmp ipAdEntryId {attributes 19} ipAddrEntry ipRouteEntryId {attributes 20} ipRouteEntry ifEntryId {attributes 21} ifEntry egpNeighEntryId {attributes 22} egpNeighEntry ifId {attributes 23} interfaces 2.4 Events Events have been defined in accordance with the OSI SMI. These events include those defined for SNMP. The OSI SMI requires that events (notifications) are part of a specific managed object class definition. Accordingly the SNMP defined events have been assigned to specific objects within the MIB. Event Identifier Object coldStartEvent {events 0} system warmStartEvent {events 1} system linkDownEvent {events 2} ifEntry linkUpEvent {events 3} ifEntry snmpAuthentFailureEvent {events 4} snmp egpNeighborLossEvent {events 5} egpNeighEntry entSpecificEvent {events 6} system 2.5 Containment (Naming) Tree Definition The OSI SMI requires that object classes be bound into the containment hierarchy for purposes of naming. The binding must OIM Working Group [Page 5] RFC 1214 MIB-II-OIM April 1991 specify for the managed object class: a) the object which is superior to it in the containment hierarchy; and b) an attribute in the managed object class that is used to distinguish instances of the object at a given level in the containment hierarchy. The containment tree begins with "root". Agents in managed systems will consider root to be immediately above the "system" object in the containment hierarchy. They may ignore any relative distinguished names that precede the relative distinguished name for "system". The name bindings for objects in the OIM MIB-II are specified in section 8. 2.6 Changes from RFC 1158 The proposed successor to RFC 1158 [16] contains several minor additions that have been incorporated into this document. o The sysLocation attribute of the system managed object class is changed to GET-REPLACE. o The ipRouteMetric5 and ipRouteInfo attributes are added to the ipRouteEntry managed object class. o The textual descriptor of the snmpEnableAuthTraps is changed to snmpEnableAuthenTraps. o The PhysAddress textual convention is introduced to represent media addresses. o The definition of sysServices is clarified. o New ifType values (29-32) are defined. In addition, the textual-descriptor for the DS1 and E1 interface types is corrected. o The definition of ipForwarding is clarified. o The definition of ipRouteType is clarified. o The tcpConnState attribute is now GET-REPLACE, to support deletion of the TCB associated with a TCP connection. The definition of this object is clarified to explain this usage. o The definition of egpNeighEventTrigger is clarified. o The definition of several of the variables in the new snmp group are clarified. In addition, the OIM Working Group [Page 6] RFC 1214 MIB-II-OIM April 1991 snmpInBadTypes and snmpOutReadOnlys objects are no longer present. (However, the object identifiers associated with those objects are reserved to prevent future use.) o The definition of snmpInReadOnlys is clarified. o The ipRoutingDiscards attribute is added to the ip object. o The optional use of an implementation-dependent, small positive integer is disallowed when identifying instances of the IP address and routing tables. 3. Format of OSI Templates The format of OSI templates is defined in ISO/IEC DIS 10165-4 [6], Open Systems Interconnection - Structure of Management Information - Part 4: Guidelines for Managed Object Definition. The template definitions relevant to this document are included in Appendix 1. 4. Object Class Definitions The Internet SMI objects are recast into OSI template form using the following conventions: o MIB II groups become OSI object classes, except for the "at" group which has no attributes. o Tables become OSI object classes. o Table entries become OSI object classes. o All other object types become OSI attributes and are assigned to object classes according to their association in MIB II. The templates for the OIM MIB-II object classes are listed in alphabetical order below. atEntry MANAGED OBJECT CLASS DERIVED FROM top; CHARACTERIZED BY atEntryPkg PACKAGE -- see MIB II [16] for attribute semantics ATTRIBUTES atEntryId GET, OIM Working Group [Page 7] RFC 1214 MIB-II-OIM April 1991 atIfIndex GET-REPLACE, atPhysAddress GET-REPLACE, atNetAddress GET-REPLACE;;;

OIM Working Group [Page 56] RFC 1214 MIB-II-OIM April 1991 Appendix 1: Notational Tools for Managed Object Definition This section provides descriptions of the notational tools used to define the templates defined in this memorandum. The text is excerpted and paraphrased from reference 6. Only the templates used in this document are included here. For a complete description of the notational tools specified for OSI management, see reference 6. A1.1 Overview of Notational Tools The "Templates" defined in this clause provide a common set of tools and a common format for the representation of the various aspects of a managed object class definition and its associated naming structure. Formal definitions of each template will be found in clauses A1.3 -A1.11 inclusive; the syntactic conventions used in these formal definitions are specified in clause A1.2. Examples of the use of these tools may be found in Annex A (of 10165-4). The structure and behaviour of a managed object class is primarily defined by means of the Managed Object Class Template. This template identifies the inheritance relationships that exist between the class and other managed object classes, the packages of class specific behaviour, the attributes that are associated with the class, the notifications that the class may issue and the operations that may be performed upon the class. In order to allow re-use of parts of this specification in the specification of other managed object classes, additional templates are defined to provide for the specification of attributes (individual and group), behaviour, actions, notifications and conditional packages. These other templates are "called up" by the Managed Object Class template by means of the referencing mechanism defined in clause A1.2; this mechanism allows references to be made in one standard to specifications that are contained in other standards, hence allowing "generic" specifications to be made available for use in managed object class definitions in addition to local specifications. Templates may also be included "in-line" if so desired. The naming of a managed object class is defined by means of the Name Binding template. This template identifies the managed object class being named and defines the relative distinguished name that will be used to name instances of the class in the context of a particular superior class. This template also provides for the specification of relationships that exist between two object classes as a consequence of a particular name binding. OIM Working Group [Page 57] RFC 1214 MIB-II-OIM April 1991 A1.2 Conventions Used in Template Definitions The templates definitions contained in this clause are based on the following syntactic conventions: - Strings surrounded by [ ] delimit parts of the template that may either be present or absent in each instance of use of the template. If the closing brace is followed by an asterisk, e.g., [ ], the contents of the braces may appear zero or more times. The circumstances under which these parts of the definition may be omitted or repeated are dependent upon the template type; - Strings surrounded by < > delimit strings that must be replaced in each instance of use of the template. The structure and meaning of the replacement string is dependent upon the string type; - Upper case strings denote Keywords which are required to be present in each instance of use of the template, unless they are enclosed in [ ]; - The solidus, \|, is used to separate alternative strings in the template; - Spaces and carriage returns are significant only as string delimiters; - In order to simplify the structure of the templates, particularly where the same syntactic structure is repeated in the template definitions, supporting syntactic definitions may be defined. If any such supporting syntactic definitions are required in order to complete the template definition, these appear following the keywords "supporting productions" at the end of the template definition. These supporting definitions take the general form definition-label-> syntactic-definition where definition-label allows the definition to be referenced by the template definition and syntactic-definition gives the expansion of the definition, using the above notational rules; - The templates themselves have the general structure: <template-label>TEMPLATE NAME [ELEMENT NAME [<element-definition>] ;] [REGISTERED AS <object-identifier> ;] OIM Working Group [Page 58] RFC 1214 MIB-II-OIM April 1991 [supporting productions [<definition-label> -> <syntactic-definition >]] Each instance of use of a template therefore declares a template- label by which that instance may be referenced from other templates, and if the REGISTERED AS clause is present, assigns a value of an ASN.1 OBJECT IDENTIFIER under which the instance has been registered; - Semicolons are used to mark the end of each distinct element in the template. In an instance of use of the template, any text inserted between a semicolon and the next valid keyword is assumed to be a comment; - The notation used for representing object identifiers is the normal notation defined in ASN.1 for object identifier values; i.e., the production: object-identifier-> <ASN.l ObjectIdentifierValue notation> is assumed to be a supporting production for all template definitions in this document; - Further definitions, such as the nature of the element definitions, follow the syntactic definition of the template; - Template labels shall be unique within the standard or document in which they are declared. Where a template-label is declared in document A and referenced in document B, the reference in document B shall be prefixed by the globally unique name of document A. In the case of documents named by an internationally recognized naming authority such as [CCITT\|ISO/IEC], the registered name of the document shall be used as the identifier, such as [Recommendation X.722\|ISO/IEC 10165-4]. Where a globally unique name is not already available, it is permissible to assign the value of an OBJECT IDENTIFIER to the referenced document, and use this value as a globally unique document name. The syntax of a template-label, defined using the above notation, is defined as follows: [<document-identifier> :] < label-string> document-identifier-> "<standard-name>" \| <object-identifier> A label-string may include any number of the following characters: - upper or lower case alphabetic characters; OIM Working Group [Page 59] RFC 1214 MIB-II-OIM April 1991 - the digits 0-9; - the hyphen character (-); in any order, commencing with a lower case character. For example, the following template-label: "ISO/IEC 10165/4":exampleObjectClass constitutes a globally unique label for the definition of exampleObjectClass contained in Annex A of 10165-4. Label references that are not prefixed by a document-identifier are assumed to refer to labels declared in the document in which the reference appears. - Whenever a template-label is present in a template as a pointer to another template, it may be replaced by the entire text of the referenced template itself (including the template's label). A1.3 Managed Object Class Template A1.3.1 Overview The Managed Object Class template forms the basis of the formal definition of a managed object. Elements in the template allow the class to be placed at the appropriate node of the inheritance tree, the various attributes of the class to be specified, and the behaviour of the class to be defined. The major elements of the definition are: - Inheritance. Each managed object class defines the superclass(es) from which it has been derived. All characteristics of the superclass(es) are inherited by the subclass; the subclass definition may add to these characteristics (refinement) but may not remove any characteristics of the superclass. Ultimately, all classes are subclasses of TOP; - Allomorphs. If the class supports allomorphism, the set of classes that are legitimate allomorphic views of the class must be defined. These classes must all be superclasses of the class being defined; - Mandatory Packages. The managed object class definition includes the packages of behaviour, attributes, operations and notifications that provide a complete specification of the OIM Working Group [Page 60] RFC 1214 MIB-II-OIM April 1991 behaviour that is common to all instances of the class; - Conditional Packages. The managed object class definition includes the specification of packages of behaviour, attributes, operations and notifications that are present or absent in instances of that class as a consequence of a specified condition; Note: Attributes, Operations and Notifications that form part of a class definition may only be omitted from an instance of that class if they are defined as features of a Conditional Package and are omitted in accordance with the condition defined for that package. - Class Naming. The managed object class definition must include a class name which may be used to refer to the class in CMIP. This is achieved by registration of an Object Identifier value which corresponds to the class. A1.3.2 Template Structure <class-label> MANAGED OBJECT CLASS [DERIVED FROM <class-label> [, <class-label>]; ] [ALLOMORPHIC SET <class-label> [, < class-label > ] ; ] [CHARACTERIZED BY <package-label>[,<package-label>]; ] [CONDITIONAL PACKAGES <package-label> PRESENT IF <condition-definition> [,<package-label> PRESENT IF <condition-definition>]; ] [PARAMETERS <parameter-label> [,<parameter-label>]; ] REGISTERED AS < object-identifier>; A1.3.3 Supporting Definitions DERIVED FROM <class-label>[,<class-label>]* The DERIVED FROM clause shall be present in all managed object class definitions other than "top". It is therefore the case that "top" is a superclass of all classes other than itself. The class-label identifies a managed object class from which the OIM Working Group [Page 61] RFC 1214 MIB-II-OIM April 1991 managed object class has been derived; i.e., a managed object class which is one of the object class's parents in the inheritance hierarchy. As multiple inheritance is permitted, a managed object class may have one or more parent classes. The process of inheritance (specialization) requires all the characteristics of the superclass(es) other than DERIVED FROM and ALLOMORPHIC SET to be included in the definition of the subclass. If it is intended that the subclass be allomorphic, the definition of the subclass shall include a ALLOMORPHIC SET clause that explicitly defines the set of classes that the subclass is allomorphic to. Where multiple inheritance results in the same element definition being multiply imported (as could happen, for example, if two parent superclasses contain the same attribute), the subclass is assumed to contain a single copy of the definition concerned. Characteristics that are inherited from a superclass shall not be repeated in the documentation of the subclass unless one of the techniques described in ISO/IEC 10165-4 for extending or modifying an element of the superclass is being used. The DERIVED FROM clause is therefore presumed to automatically import all inheritable elements of definition from the superclass definition(s). There may be augmented or modified by elements defined within the CHARACTERISED BY, CONDITIONAL PACKAGES, and PARAMETER constructs. ALLOMORPHIC SET <class-label>[,<class-label>]* The Allomorphic Set allows a set of superclasses to be identified that are "backwards compatible" with the managed object class. Thus, if managed object class A identifies classes B and C as members of its allomorphic set, it is possible to operate on an instance of class A as if it were an instance of class B or C. The definition of allomorphic forms allows, for example, the d
