Internet Draft SNMPv2 MIB for UDP June 1995
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 a subset of OSI's Abstract
Syntax Notation One (ASN.1) [1], termed the Structure of Management
Information (SMI) [2].
This document is the MIB module which defines managed objects for
managing implementations of the User Datagram Protocol (UDP) [3].
The managed objects in this MIB module were originally defined using the
SNMPv1 framework as a part of MIB-II [4]. This document defines the
same objects for UDP using the SNMPv2 framework.
