Abstract

A management system contains: several (potentially many) nodes, each with a processing entity, termed an agent, which has access to management instrumentation; at least one management station; and, a management protocol, used to convey management information between the agents and management stations. Operations of the protocol are carried out under an administrative framework which defines authentication, authorization, access control, and privacy policies.

1. Introduction

A management system contains: several (potentially many) nodes, each

with a processing entity, termed an agent, which has access to

management instrumentation; at least one management station; and, a

management protocol, used to convey management information between

the agents and management stations. Operations of the protocol are

carried out under an administrative framework which defines

authentication, authorization, access control, and privacy policies.

Management stations execute management applications which monitor and

control managed elements. Managed elements are devices such as

hosts, routers, terminal servers, etc., which are monitored and

controlled via access to their management information.

Management information is viewed as a collection of managed objects,

residing in a virtual information store, termed the Management

Information Base (MIB). Collections of related objects are defined

in MIB modules. These modules are written using an adapted subset of

OSI's Abstract Syntax Notation One (ASN.1) [1]. It is the purpose of

this document, the Structure of Management Information (SMI), to

define that adapted subset, and to assign a set of associated

administrative values.

The SMI is divided into three parts: module definitions, object

definitions, and, notification definitions.

(1) Module definitions are used when describing information modules.

An ASN.1 macro, MODULE-IDENTITY, is used to concisely convey the

semantics of an information module.

(2) Object definitions are used when describing managed objects. An

ASN.1 macro, OBJECT-TYPE, is used to concisely convey the syntax

and semantics of a managed object.

(3) Notification definitio...
