Book Reviews of Network Warrior
Book Review: What a great book
Summary: 5 Stars
I loved three things about this book:
1- The simple style it conveys from cover to cover. Every subject in network administration is divided into short but detailed chapters in order to keep the reader's attention focused. Anyone can write a book that lists an experienced user's knowledge of the subject, but it takes a real engineer to compile the data in small doses of knowledge.
2- The clarity of the information mentioned. The author uses the same style of defining the problem, suggesting the best solution, and detailing the technical commands to implement the best solution.
Common pitfalls, problem symptoms, and real life examples are provided as well.
3- The deep coverage of the subject at hand. The author goes over almost every subject in network administration, but without the extra fluff. It's really what you need to know.
Definitely a great buy.
Book Review: Excellent book
Summary: 5 Stars
I found this book to be absolutely remarkable. The text at the top about it being what you need to be that wasn't on the CCNA is all too true.
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.
Book Review: A good effort, needs a little more depth in some places
Summary: 4 Stars
Network Warrior is another quite useful O'Reilly effort in the Cisco handbook space. It really is potentially handy for many real-time network operators. One thing I wish the author had spent much more time on is Ethernet switching. He does dig into some of the quirks of configuring VLANs in the Cisco environment but to my way of thinking associated subjects (mirroring, span port config, spanning tree troubleshooting) need a lot more exposure. One area that cannot be talked about enough are the twists involved in setting up spanning tree through a complex VLAN network. Another potentially vital topic involves interoperating with other vendors' equipment in a spanning tree network. I bought this book hoping for more exposure than I got in those areas. This is the only reason I didn't give it five.Book Review: Great next read after getting your CCNA!
Summary: 4 Stars
One of the best networking books I have read, period. Not just how it works, but why it works and should be configured. After you study and obtain your CCNA, this is the next read that will fill in many information holes.
Highly recommended.
Book Review: Essential reading for both the exams and everyday networking.
Summary: 5 Stars
In preparation for the CCNA exam, I have gone through several networking books, both Cisco-specific and otherwise. I had thought that the official Cisco Press CCNA set was the best resource... until I took a chance on this tome. While I have found the Wendell Odom CCNA set to be the definitive guide to CCNA/CCENT material, I now must admit that this book is nearly - or even exactly - as essential as a CCNA exam prep guide. While the other guides read like textbooks, giving the reader adequate conceptual and theoretical information, this book felt like a nice long chat with a seasoned "network warrior" about real-world, everyday issues faced by network engineers.
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.
