Enhance your purchase
Written by networking veteran with 20 years of experience, Network Warrior provides a thorough and practical introduction to the entire network infrastructure, from cabling to the routers. What you need to learn to pass a Cisco certification exam such as CCNA and what you need to know to survive in the real world are two very different things. The strategies that this book offers weren 't on the exam, but they 're exactly what you need to do your job well.
Network Warrior takes you step by step through the world of hubs, switches, firewalls, and more, including ways to troubleshoot a congested network, and when to upgrade and why. Along the way, you 'll gain an historical perspective of various networking features, such as the way Ethernet evolved. Based on the author 's own experience as well as those he worked for and with, Network Warrior is a Cisco-centric book, focused primarily on the TCP/IP protocol and Ethernet networks -- the realm that Cisco Systems now dominates. The book covers:
The type of networks now in use, from LANs, WANs and MANs to CANs
- The OSI Model and the layers involved in sending data
- Hubs, repeaters, switches, and trunks in practice
- Auto negotiation and why it 's a common problem in network slowdowns
- Route maps, routing protocols, and switching algorithms in Cisco routers
- The resilient Ethernet -- how to make things truly redundant
- Cisco 6500 multi-layer switches and the Catalyst 3750 switch
- Telecom nomenclature -- why it 's different from the data world
- T1 and DS3
- Firewall theory, designing access lists, authentication in Cisco devices
- Server load balancing technology
- Content switch module in action
- Designing QOS and what QOS does not do
- IP design and subnetting made easy
The book also explains how to sell your ideas to management, how networks become a mess as a company grows, and why change control is your friend. Network Warrior will help network administrators and engineers win the complex battles they face every day.

What set this book apart from the thousands of pages (hey, I'm dedicated!) of material I'd already covered?
- CatOS commands; the new Cisco Press books barely mention that CatOS exists!
- anecdotes and real-world examples; even if you know how it *should* work, this book reveals how it *does* work
- objective viewpoint on Cisco technology; no "Cisco's way is the best way" dogma here
- meaningful discussion of high-end, core-strength equipment; everything in the Wendell Odom set focused exclusively on Catalyst 2960 switches and one model of router
- frank, direct, humorous, and engaging style; half the material I've covered previously was dreadfully dull
- illustrations for every concept; this makes my life so much easier when trying to explain things to fellow junior technicians
While the book may seem daunting at nearly 600 pages, I'm flying through it at about 80-100 pages per day. The text is very engaging, and the author's way of phrasing things is informative and structured yet very flowing and casual. I feel that every chapter contains some point, if not several points and concepts, that I wouldn't have known from the other books out there. What is possibly the best feature of this book is the real-world, realistic approach to every concept and issue. The Cisco Press books seem to assume that the reader will be using 2960 access layer switches running IOS 12.2 or better. Network Warrior does not make this assumption. The author makes the realistic assumption that the reader's network could have all kinds of gear networked together, and thus includes information about CatOS as well as a wide variety of Cisco hardware. Also included are some quick and dirty tricks to save time, money, and effort. For example, I didn't know that I could abbreviate almost any command in IOS ("sho" instead of "show", etc.) and still get the same result until I read this book. While I feel that the by-the-book approach of the Cisco Press material is necessary for building a clear foundation, I feel that this book's get-the-job-done take on networking is a necessary follow-up.
The book assumes some working knowledge of networking, but not too much. It doesn't explain the bare basics of networking, nor does it give a history lesson about the histories of each and every cabling standard and networking protocol. It's not a total replacement for a book about networking basics, nor a beginner's guide to the CCNA and/or Cisco equipment. What it does instead is reshape one's conception of what a network is and how to manage it. What it does as well, and does excellently, is fill in the gaps that sorely needed filling in the great mass of other Cisco material out there. If you are preparing for the CCNA, or if you have already passed and think you know all you'll need to know about managing Cisco networks, this book was written for you. I guarantee you will learn something new.
If you are studying for a CCNA certification yourself, you have to ask yourself one question - are studying to pass a test, or do you want to learn something? If you want to learn, get a Network Engineering job, or go to a GOOD school. If you want to pass a test, then read the book(s), and study the practice exams. There's no short cuts around either road. This book, by Gary Donahue, promises to bridge that missing link between the classroom and the server room. I haven't read all of it of course (I just got it today), but I had breezed through a digital copy of the book before I actually bought a physical copy from Amazon. This book is 1.25 inches thick and comes with a 45-Day access to the digital version from Safari. However, there just is no comparison between a solid book you can hold in your hands and a digital book. A REAL book is something you can mark with notes and highlights - that's how you can truly own a book.
But I also live in a small apartment in New York City, so shelve space is also an issue. Plus digital books make great reference materials, searches take seconds. It's a balance, there is no panacea for all situations.
My order from Amazon.com came in TWO days, and I only chose the FREE Super Saver Shipping option, so I didn't even pay extra. Only the New York sales tax (Arrgh!). I'm very happy with my purchase, and is very pleased with the U.S. government for building the internet for Amazon.com to do business in. I'm giving this book FOUR stars, because there is not even a single mention of "ROLLOVER cable" in it. Yes, I am deliberately being picky.
Mr. Donahue's writing style is what makes the book. He explains often complex topics in a manner of a grizzled old veteran telling a war story. He doesn't break down into the deep technical details, he tells you how it works and why you should do it the way he's telling you to.
There's more that goes into being a network monkey than just knowing what commands to type, and the insight he offers into the more social aspects of how to be a network guy are invaluable. It is my honest opinion that the final chapters, particularly those on how to deal with management and being a nerd, should be required reading for anyone that works at a technology company.
It is my sincere hope that Mr. Donahue continues his writing career and takes his style of communicating to other complex subjects. I would love a dissertation of BGP written in the same manner, for example.
If you're a bright shiny new CCNA, or studying for the CCNA, and you're serious about pursuing a career in networking, buy this book. It won't help you pass any exams, but you'll find it as one of your favorite reference materials nonetheless.

It's very Cisco orientated, but that's no surprise, given Cisco's market penetration, nor is it a terribly bad thing...I suppose it just reflects the way the world is. The only time it really grated on me was regards firewalls and server load balancers, since Cisco's offerings in these spaces suck like a Dyson on steroids (Mr. Donohue's praise for the late, unlamented Local Director series, for example, is very puzzling to me - but each to their own, I guess). However, it would have been nice for it to be a bit more platform-agnostic, I think. Also, BGP gets no more than a passing nod, really, and for that critically important protocol to be dismissed with what boils down to "Well, you probably won't need to config BGP unless you work for an ISP" is a bit weak.
Apart from that, pretty good.
