Internet Draft                 Event MIB                   13 March 1998


1.  Abstract

This memo defines an experimental 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 monitoring of MIB objects and taking action through events.

2.  The SNMP Network Management Framework

{The following boilerplate is out of date.  It will be replaced when
SNMPv3 boilerplate is available.}

The SNMP Network Management Framework presently consists of three major
components.  They are:

  the SMI, described in RFC 1902 [1] - the mechanisms used for
  describing and naming objects for the purpose of management.

  the MIB-II, STD 17, RFC 1213 [2] - the core set of managed objects for
  the Internet suite of protocols.

  the protocol, RFC 1157 [3] and/or RFC 1905 [4], - the protocol for
  accessing managed objects.

The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.


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.

Internet Draft                 Event MIB                   13 March 1998


3.  Overview

This MIB is based heavily on the RMON and Manager-to-Manager MIBs. It
depends on the services of the SNMPv3 Management Target and Notification
MIBs and is nicely complemented by the Distributed Management Expression
MIB.

All of these components must suit either a relatively powerful manager
or mid-level manager, as well as a somewhat more limited self-managing
system.


4.  Known Problems

The compliance section is missing.
