Dear Reader:

Coriolis Technology Press was founded to create a very elite group of books: the ones you keep closest to your machine. Sure, everyone would like to have the Library of Congress at arm’s reach, but in the real world, you have to choose the books you rely on every day very carefully.

To win a place for our books on that coveted shelf beside your PC, we guarantee several important qualities in every book we publish. These qualities are:

•Technical accuracy—It’s no good if it doesn’t work. Every Coriolis Technology Press book is reviewed by technical experts in the topic field, and is sent through several editing and proofreading passes in order to create the piece of work you now hold in your hands.

•Innovative editorial design—We’ve put years of research and refinement into the ways we present information in our books. Our books’ editorial approach is uniquely designed to reflect the way people learn new technologies and search for solutions to technology problems.

•Practical focus—We put only pertinent information into our books and avoid any fluff. Every fact included between these two covers must serve the mission of the book as a whole.

•Accessibility—The information in a book is worthless unless you can find it quickly when you need it. We put a lot of effort into our indexes, and heavily cross−reference our chapters, to make it easy for you to move right to the information you need.

Here at The Coriolis Group we have been publishing and packaging books, technical journals, and training materials since 1989. We’re programmers and authors ourselves, and we take an ongoing active role in defining what we publish and how we publish it. We have put a lot of thought into our books; please write to us at ctp@coriolis.com and let us know what you think. We hope that you’re happy with the book in your hands, and that in the future, when you reach for software development and networking information, you’ll turn to one of our books first.

Acknowledgments

It’s always exciting when you get to the acknowledgments because that means the book is almost done. First off, I must thank Erin for putting up with me during the writing of this book. She is a wonderful person who is as smart as she is good looking and puts up with a lot of extra responsibility while I am working on books. I also need to thank Albert Ip and Hanson Nottingham for their defined knowledge of the Cisco switches. Thanks to my favorite English teacher, Mr. Strange, for being the one who originally thought I would be a great writer some day, and I guess it shows here in my third book. Coriolis deserves many thanks. A few people in particular at Coriolis need to be thanked: Steve Sayre, for believing in my idea of a Cisco Switching Black Book; my project editor for the second time, Toni Zuccarini Ackley; Tiffany Taylor for finding all my mistakes; Charlotte Carpentier and Shari Jo Hehr for handling the many contract issues for this book; Jody Winkler for making the cover; Carla Schuder for making the inside of the book look good; and Paul LoPresto for all his help in acquisitions.
