This preface describes the purpose, audience, organization, and conventions for the ATM Switch Router Troubleshooting Guide and provides information on how to obtain related documentation.
Failures in internetworks are characterized by certain symptoms. These symptoms might be general (clients that are unable to access specific servers) or more specific (routes that are not in the routing table). Each symptom can be traced to one or more problems or causes by using specific troubleshooting tools and techniques. When you know what the problem is, you can take steps to fix it.
The goal of this guide is to help you isolate and resolve the most common connectivity and performance problems for your Cisco ATM switch router as it fits into your network environment. This guide describes how to define symptoms, identify problems, and implement solutions in Cisco ATM switch router environments. This guide does not describe troubleshooting router connections and configuration. For router troubleshooting see the "Internetwork Troubleshooting Guide."
This preface describes who should read the ATM Switch Router Troubleshooting Guide, how it is organized, and its document conventions.
This publication is a stand-alone document for experienced network administrators responsible for configuring and maintaining the ATM switch router.
Administrators should have hands-on experience in configuring, administering, and troubleshooting a network, should know how to configure routers, switches, and other internetwork devices, and should be familiar with the protocols and media that their hardware supports. Awareness of the basic topology of their network is also essential.
The major sections of this guide are as follows:
| Chapter | Title | Description |
