tion with onsite training. He is currently working with a large international organization

with most major networking technologies, developing a specific expertise in secure, con-
verged network infrastructures based largely on Cisco hardware. Before that, he accumu-

Dedications
As always, this book is dedicated to the most important people in my life: my wife,
Marci, and my two daughters, Lauren and Kara. Their love, encouragement, and sup-
port carry me along. I’m so grateful to God, who gives endurance and encouragement
(Romans 15:5), and who has allowed me to work on projects like this.

Acknowledgments
It has been my great pleasure to work on another Cisco Press project. I enjoy the net-
working field very much, and technical writing even more. And more than that, I’m
thankful for the joy and inner peace that Jesus Christ gives, making everything more
abundant.
Technical writing may be hard work, but I’m finding that it’s also quite fun because I’m
working with very good friends at Cisco Press. Even after nearly 15 years, I still get to
work with Brett Bartow and Chris Cleveland, the finest editors I know.
I am very grateful for the insight, suggestions, and helpful comments that Geoff Tagg
and Joe Harris contributed. Their knowledge and attention to detail helped make this a
more well-rounded book and me a more educated author.
