Introduction

CCNP Practical Studies: Troubleshooting is part of the Practical Studies series of Cisco Press books designed to prepare readers for the CCNP exams and real-world application of LAN and WAN technologies. Unfortunately, life is not just a checklist and neither is supporting networks. However, if you know how things are supposed to work, use a consistent troubleshooting method and layered approach, apply your skills through hands-on application, and have a positive attitude, you are most certainly on your way to shooting trouble before it shoots you.

Troubleshooting skills are a must-have for every CCNA, CCNP, and CCIE today. There is an increasing demand for practical application of the knowledge learned in Cisco and other internetworking classes. People learn by doing. Practice makes perfect. Employers want people with degrees and certifications, but they really need people who can perform the job that their resume says they can. This book gives you a practical advantage over the competition through real-world application of internetworking topics. It is designed for CCNAs and CCNPs as well as the want-to-be seeking practical experience in the topics covered on the CCNP Troubleshooting exam. Because material in this book is very helpful for anyone in or pursuing a support career, even CCIEs and other support professionals may enjoy reviewing the book to sharpen their troubleshooting skills. The scope is limited to TCP/IP and routing and switching and to a lesser extent Novell IPX troubleshooting.
