Network Working Group T. Cox Request For Comments: 1304 K. Tesink Editors Bell Communications Research February 1992 Definitions of Managed Objects for the SIP Interface Type Status of this Memo This RFC specifies an IAB standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "IAB Official Protocol Standards" for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing SIP (SMDS Interface Protocol) objects. Table of Contents 1. The Network Management Framework ............................ 2 2.

The Network Management Framework The Internet-standard Network Management Framework consists of three components. They are: RFC 1155 [3] which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management. RFC 1212 [9] defines a more concise description mechanism, which is wholly consistent with the SMI. RFC 1156 [4] which defines MIB-I, the core set of managed objects for the Internet suite of protocols. RFC 1213 [6], defines MIB- II, an evolution of MIB-I based on implementation experience and new operational requirements. RFC 1157 [5] which defines the SNMP, the protocol used for network access to managed objects. The Framework permits new objects to be defined for the purpose of experimentation and evaluation. 2. Objects 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) International Standard 8824 [7] defined in the SMI. In particular, each object has a name, a syntax, and an encoding. The name is an object identifier, an administratively assigned name, which specifies an object type. 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 OBJECT DESCRIPTOR, to also refer to the object type. The syntax of an object type defines the abstract data structure corresponding to that object type. The ASN.1 language is used for this purpose. However, the SMI RFC 1155 [3] purposely restricts the ASN.1 constructs which may be used. These restrictions are explicitly made for simplicity. The encoding of an object type is simply how that object type is represented using the object type's syntax. Implicitly tied to the notion of an object type's syntax and encoding is how the object type is represented when being transmitted on the network. The SMI specifies the use of the basic encoding rules of ASN.1 International Standard 8825 [8], subject to the additional requirements imposed by the SNMP.
