Acknowledgments
Internetworking must be built around the business at hand in order to provide easy access to
pertinent information regardless of location, time, or system. Much of the information included in
this book is based on questions I have received in class. I have to send out a special thanks to all
of my students and coworkers from TCP/IP to CCNA to CCNP and others over the years who have
kept me on my toes. I wouldn't want to forget my technical reviewers, who have helped me
make this book what it is today. Thank you Scott Morris, Rick Burts, Marty Adkins, Mark Olivo,
and Chris Heffner. I would also like to thank Charlie Mann for testing the hands-on scenarios and
Trouble Tickets.

Foreword
CCNP Practical Studies: Troubleshooting is designed to provide you with another vehicle to
obtain hands-on experience, which is a critical component of any preparation program for the
Cisco Certified Network Professional exams. The detailed lab scenarios contained in this book
illustrate the application of key support and troubleshooting concepts covered on the CCNP
Troubleshooting exam, helping you master the advanced practical skills you need to install,
configure, and operate LAN, WAN, and dial access services for networks from 100 to more than
500 nodes. With the introduction of performance-based testing elements to the CCNP exams,
these hands-on skills are of critical importance to succeeding on the exam and in your daily job
as a CCNP professional. This book was developed in cooperation with the Cisco Internet Learning
Solutions Group. Cisco Press books are the only self-study books authorized by Cisco for CCNP
exam preparation.
Cisco and Cisco Press present this material in text-based format to provide another learning
vehicle for our customers and the broader user community in general. Although a publication
does not duplicate the instructor-led or e-learning environment, we acknowledge that not
everyone responds in the same way to the same delivery mechanism. It is our intent that
presenting this material via a Cisco Press publication will enhance the transfer of knowledge to a
broad audience of networking professionals.
Cisco Press will present lab manuals on existing and future exams through these Practical
Studies titles to help achieve Cisco Internet Learning Solutions Group's principal objectives: to
educate the Cisco community of networking professionals and to enable that community to build
and maintain reliable, scalable networks. The Cisco Career Certifications and classes that
support these certifications are directed at meeting these objectives through a disciplined
approach to progressive learning. To succeed on the Cisco Career Certifications exams, as well
as in your daily job as a Cisco-certified professional, we recommend a blended learning solution
that combines instructor-led, e-learning, and self-study training with hands-on experience. Cisco
Systems has created an authorized Cisco Learning Partner program to provide you with the most
highly qualified instruction and invaluable hands-on experience in lab and simulation
environments. To learn more about Cisco Learning Partner programs available in your area,
please go to: www.cisco.com/go/training.
The books that Cisco Press creates in partnership with Cisco Systems meet the same standards
for content quality demanded of our courses and certifications. It is our intent that you will find
this and subsequent Cisco Press certification and training publications of value as you build your
networking knowledge base.

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.
