Network Working Group R. Stine, Editor
Request for Comments: 1147 SPARTA, Inc.
FYI: 2 April 1990
FYI on a Network Management Tool Catalog:
Tools for Monitoring and Debugging TCP/IP Internets
and Interconnected Devices
Status of this Memo
The goal of this FYI memo is to provide practical informa-
tion to site administrators and network managers. This memo
provides information for the Internet community. It does
not specify any standard. It is not a statement of IAB pol-
icy or recommendations. Comments, critiques, and new or
updated tool descriptions are welcome, and should be sent to
Robert Stine, at stine@sparta.com, or to the NOCTools work-
ing group, at noctools@merit.edu.
Distribution of this memo is unlimited.
1. Introduction
This catalog contains descriptions of several tools avail-
able to assist network managers in debugging and maintaining
TCP/IP internets and interconnected communications
resources. Entries in the catalog tell what a tool does,
how it works, and how it can be obtained.
The NOCTools Working Group of the Internet Engineering Task
Force (IETF) compiled this catalog in 1989. Future editions
will be produced as IETF members become aware of tools that
should be included, and of deficiencies or inaccuracies.
Developing an edition oriented to the OSI protocol suite is
also contemplated.
The tools described in this catalog are in no way endorsed
by the IETF. For the most part, we have neither evaluated
the tools in this catalog, nor validated their descriptions.
Most of the descriptions of commercial tools have been pro-
vided by vendors. Caveat Emptor.
1.1 Purpose
The practice of re-inventing the wheel seems endemic to the
field of data communications. The primary goal of this
IETF NOCTools Working Group [Page 1]
RFC 1147 FYI: Network Management Tool Catalog April 1990
document is to fight that tendency in a small but useful
way. By listing the capabilities of some of the available
network management tools, we hope to pool and share
knowledge and experience. Another goal of this catalog is
to show those new in the field what can be done to manage
internet sites. A network management tutorial at the end of
the document is of further assistance in this area.
Finally, by omission, this catalog points out the network
management tools that are needed, but do not yet exist.
There are other sources of information on available network
management tools. Both the DDN Protocol Implementation and
Vendors Guide and the DATAPRO series on data communications
and LANs are particularly comprehensive and informative.
The DDN Protocol Implementation and Vendors Guide addresses
a wide range of internet management topics, including
evaluations of protocol implementations and network
analyzers.* The DATAPRO volumes, though expensive (check
your local university or technical libraries!), are good
surveys of available commercial products for network manage-
ment. DATAPRO also includes tutorials, market analyses,
product evaluations, and predictions on technology trends.
1.2 Scope
The tools described in this document are used for managing
the network resources, LANs, and devices that are commonly
interconnected by TCP/IP internets. This document is not,
however, a "how to" manual on network management. While it
includes a tutorial, the coverage is much too brief and gen-
eral to serve as a sole source: a great deal of further
study is required of aspiring network managers. Neither is
this catalog is an operations manual for particular tools.
Each individual tool entry is brief, and emphasizes the uses
to which a tool can be put. A tool's documentation, which
in some cases runs to hundreds of pages, should be consulted
for assistance in its installation and operation.
1.3 Overview
Section 1 describes the purpose, scope, and organization of
this catalog.
Section 2 lists and explains the standard keywords used in

* Instructions for obtaining the DDN Protocol Guide are
given in Section 7 of the appendix.

RFC 1147 FYI: Network Management Tool Catalog April 1990
the tool descriptions. The keywords can be used as a sub-
ject index into the catalog.
Section 3, the main body of the catalog, contains the
entries describing network management tools. The tool
entries in Section 3 are presented in alphabetical order, by
tool name. The tool descriptions all follow a standard for-
mat, described in the introduction to Section 3.
Following the catalog, there is an appendix that contains a
tutorial on the goals and practice of network management.
1.4 Acknowledgements
The compilation and editing of this catalog was sponsored by
the Defense Communications Engineering Center (DCEC), con-
tract DCA100-89-C-0001. The effort grew out of an initial
task to survey current internet management tools. The cata-
log is largely, however, the result of volunteer labor on
the part of the NOCTools Working Group, the User Services
Working Group, and many others. Without these volunteer
contributions, the catalog would not exist. The support
from the Internet community for this endeavor has been
extremely gratifying.
Several individuals made especially notable contributions.
Mike Patton, Paul Holbrook, Mark Fedor and Gary Malkin were
particularly helpful in composition and editorial review,
while Dave Crocker provided essential guidance and
encouragement. Bob Enger was active from the first with the
gut work of chairing the Working Group and building the
catalog. Phill Gross helped to christen the NOCTools Work-
ing Group, to define its scope and goals, and to establish
its role in the IETF. Mike Little contributed the formative
idea of enhancing and publicizing the management tool survey
through IETF participation.
Responsibility for any deficiencies and errors remains, of
course, with the editor.

2. Keywords
This catalog uses "keywords" for terse characterizations of
the tools. Keywords are abbreviated attributes of a tool or
its use. To allow cross-comparison of tools, uniform key-
word definitions have been developed, and are given below.
Following the definitions, there is an index of catalog
entries by keyword.
2.1 Keyword Definitions
The keywords are always listed in a prefined order, sorted
first by the general category into which they fall, and then
alphabetically. The categories that have been defined for
management tool keywords are:
o+ the general management area to which a tool
relates or a tool's functional role;
o+ the network resources or components that are
managed;
o+ the mechanisms or methods a tool uses to perform
its functions;
o+ the operating system and hardware environment of a
tool; and
o+ the characteristics of a tool as a hardware pro-
duct or software release.
The keywords used to describe the general management area or
functional role of a tool are:
Alarm
a reporting/logging tool that can trigger on specific
events within a network.
Analyzer
a traffic monitor that reconstructs and interprets pro-
tocol messages that span several packets.
Benchmark
a tool used to evaluate the performance of network com-
ponents.

a tool that can change the state or status of a remote
network resource.
Debugger
a tool that by generating arbitrary packets and moni-
toring traffic, can drive a remote network component to
various states and record its responses.
