Basic Dial NMS Implementation Guide

LE

Preface

Purpose

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).

Audience

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-onexperience 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.

Scope

This guide provides guidelines and a case study for:

Designing a dial NMS.

Collecting and using data-managementstreams 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.

Protocols—SNMPand NTP.

Functions—Syslog,modem call records, Cisco IOScommand-lineinterface (CLI), Log File Rotator, Device Navigator,web-basedmanagement, and War Dialer.

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