tailieunhanh - Internetworking Troubleshooting Handbook

Internetworks come in a variety of topologies and levels of complexity—from single-protocol, point-to-point links connecting cross-town campuses, to highly meshed, large-scale wide-area networks (WANs) traversing multiple time zones and international boundaries. The industry trend is toward increasingly complex environments, involving multiple media types, multiple protocols, and often interconnection to “unknown” networks. Unknown networks may be defined as a transit network belonging to a Internet service provider (ISP) or a telco that interconnects your private networks. In these unknown networks, you do not have control of such factors as delay, media types, or vendor hardware | Preface No single troubleshooting resource can anticipate every possible glitch that can be encountered in internetworks. But any significant contribution that can be made toward preventing connectivity blockages is a step in the right direction. We hope that this publication contributes to the body of knowledge that makes networks more manageable. Audience Internetworking Troubleshooting Handbook is intended for network administrators who are responsible for troubleshooting internetworks that implement Cisco products and Cisco-supported protocols. Administrators should have hands-on experience in configuring administering and troubleshooting a network should know how to configure routers switches and bridges and should be familiar with the protocols and media that their hardware has been configured to support. Awareness of the basic topology of their network is also essential. Document Organization The Internetworking Troubleshooting Handbook provides the information necessary to troubleshoot many problems commonly encountered in internetworks using Cisco hardware and software products. This publication consists of the following six parts The chapters in Part 1 Introduction to Troubleshooting provide an introduction to troubleshooting techniques and an overview of common troubleshooting tools. The chapters in Part 2 Hardware Booting and Media Problems provide information for troubleshooting hardware problems LAN media problems and booting system initialization problems. The chapters in Part 3 Troubleshooting Desktop and Entreprise Routing Protocols provide information on troubleshooting common connectivity and performance problems in TCP IP Novell IPX AppleTalk IBM and other widely-implemented network environments. The chapters in Part 4 Troubleshooting Serial Lines and WAN Connections provide information on troubleshooting problems that commonly occur on serial lines and WAN links such as ISDN Frame Relay and . The chapters in Part 5 Troubleshooting Bridging
