Introduction This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects used for managing multiple logical and physical entities managed by a single SNMP agent. 2. The SNMP Network Management Framework The SNMP Network Management Framework presently consists of three major components. They are: o the SMI, described in RFC 1902 [1], - the mechanisms used for describing and naming objects for the purpose of management. o the MIB-II, STD 17, RFC 1213 [2], - the core set of managed objects for the Internet suite of protocols. o the protocol, RFC 1157 [6] and/or RFC 1905 [4], - the protocol for accessing managed information. Textual conventions are defined in RFC 1903 [3], and conformance statements are defined in RFC 1904 [5]. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. This memo specifies a MIB module that is compliant to the SNMPv2 SMI. A semantically identical MIB conforming to the SNMPv1 SMI can be produced through the appropriate translation. 2.1. Object Definitions Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) defined in the SMI. In particular, each object type is named by an OBJECT IDENTIFIER, an administratively assigned name. The object type together with an object instance serves to uniquely identify a specific instantiation of the object. For human convenience, we often use a textual string, termed the descriptor, to refer to the object type. McCloghrie & Bierman Standards Track [Page 2] RFC 2037 Entity MIB using SMIv2 October 1996 3. Overview There is a need for a standardized way of representing a single agent which supports multiple instances of one MIB. This is presently trueShow full document text
