This Internetworking Solutions Guide (ISG) describes how to implement and operate a dial network management system (NMS) that provides management functions for a dial Internet access service (DIAS).


This guide is intended for network engineers and operators who implement and operate dial NMS systems.

This guide assumes that you have the following level of knowledge and experience:

An understanding of NMS protocols, such as Simple Network Management Protocol (SNMP), Network Time Protocol (NTP), and syslog.

Hands-on experience working with Cisco routers, IOS technologies, and UNIX.

Success configuring a Cisco network access server (NAS) for basic IP modem services.

A Cisco Certified Network Associate (CCNA) certificate or equivalent level of experience.


This guide provides guidelines and a case study for:

Designing a dial NMS.

Collecting and using data-management streams to operate a dial access network.

Managing important connection events and alarms for statistical analysis.

Reporting on the performance of a DIAS.

Addressing the perception problems that are commonly associated with dial access networks.

This guide describes the following network protocols, functions, and NMS applications:

Protocols—SNMP and NTP.

Functions—Syslog, modem call records, Cisco IOS command-line interface (CLI), Log File Rotator, Device Navigator, web-based management, and War Dialer.

NMS applications—UCD-SNMP, Multi Router Traffic Grapher (MRTG), HP OpenView (HPOV), and CiscoWorks 2000 Resource Manager Essentials (CW2000 RME).

This guide does not provide the following information:

Descriptions about the basics of network management.

Windows NT-based management of Cisco routers.

Detailed authentication, authorization, and accounting (AAA).

Basic access server configurations.

Information about integrating high-end NMS systems in to a dial access environment.

Optional keyword or argument that you enter with a required keyword or argument.


Set of characters that you enter. Do not use quotation marks around the character string, or the string will include the quotation marks.


Information that appears on the screen.

^ or Ctrl

Control key—for example, ^D means press the Control and the D keys simultaneously.

< >

Nonprinting characters, such as passwords.


Comment line at the beginning of a line of code.

Caution Means reader be careful. In this situation, you might do something that could result in equipment damage or loss.

Note Means reader take note. Notes contain helpful suggestions or reference to materials not contained in this manual.
