Dry, but Useful...
I am reviewing Cisco Catalyst QOS: Quality of Service in Campus Networks (ISBN: 1-58705-120-6). The book is 400 pages in length and is divided into 2 sections, Fundamental QOS Concepts and Advanced QOS Concepts. It includes coverage of QOS functionality on 2900, 3500, 4000 & 6500 series Cisco Catalyst Switches. The book states that it is intended for network engineers who work with Catalysts and seek a deeper understanding of QOS. Add CCNP level switch understanding to that list, at the very least. The book's authors are Mike Flannagan, Richard Froom, and Kevin Turek, all CCIE-level engineers who work directly for Cisco in Research Triangle Park. Notice the presence of "authors", "engineers" and "research" in one sentence... a fearful combination to say the least. Buckle up, kids, it's gonna be a bumpy ride.
My Reading Experience:
I set out to read this book as an attempt to get an understanding of QOS for my CCIE studies. Oops, Rich didn't read the fine print. This book isn't really so much a book about QOS concepts in general as it is an implementation guide for utilizing QOS on a Catalyst network. Works out okay for me, though, because my company runs 4000 and 6500 series Catalysts and the information will prove quite useful as we roll out QOS. For my CCIE studies, however, I will still need to pick up a book that is somewhat more general, like maybe the Cisco DQOS Exam Certification Guide or Cisco IOS 12.0 Quality of Service. Luckily for me, the book spends the first 2 chapters teaching the underlying QOS concepts for the features that are discussed in the remainder of the book. After the first 2 chapters, the Fundamentals section is finished up with a 2-chapter overview of the QOS support on the various Catalyst platforms.
Part 2 of the book presents QOS implementation on the various Catalyst platforms. I believe the intention of the authors was for the reader to only read the specific chapters in part 2 that pertained to the specific equipment they'd be using. I say this because the chapters repeat a lot of the same information. From the standpoint of this being an implementation guide, it's good that each chapter stands on its own and you don't have to read the entire book to get an understanding of QOS as it applies to your particular Catalyst platform.
The thing that makes this book unique, and the thing which I liked most about it, is the in-depth coverage of the Catalyst 6500 series. There is a chapter dedicated to 6500 by itself, which shows both hybrid and native commands for all the QOS functions. There is also a chapter that focuses on the 6500 MSFC and Flexwan modules. The last time I checked, there was exactly one book that I knew of that had any info about the 6500, Cisco LAN Switching (CCIE Professional Development series). Since my network uses 6509's with MSFC2 and FlexWAN cards, I found those chapters to be extremely useful and will be using them to implement QOS.
If I seem wishy-washy about this title, it's because I am. My recommendation depends upon what you want to accomplish. If you want to learn QOS concepts, I'd recommend reading something else, like the Cisco DQOS Exam Certification Guide. If you're actually implementing QOS in a Catalyst network, I'd recommend this book. The writing is just a little too dry and the examples are a little too abstract. I would have liked to have seen more real-world examples in plain English. Using my 5-ping rating scale, I'll give Cisco Catalyst QOS three pings - two for the beginning of the book, and one for the 6500 coverage.

Global Knowledge Instructor Review
I'm a Global Knowledge instructor who teaches the Cisco DQoS 1.0 class. This book is GREAT! It unlocked many of the QoS mysteries that I still had concerning Layer 2 and 3 on the switches. Switches perform QoS in the TCAM and other hardware resources. Because of such, it is a very complex topic. This book is a great follow-on to the Wendell Odom DQoS book or great as a stand-alone if you already understand "some" QoS. These guys cover the Modular QoS CLI (MQC) and most of what you need to deploy a solution. GREAT BOOK!

A review of "Cisco Catalyst QoS: Quality of Service in Campus Networks" by Michael Flannagan, Rochard Froom, and Kevin Turek - ISBN: 1587051206.
As a network engineer for a Cisco certified partner I deal with a wide variety of technologies. Consistently one of the most complex subjects I deal with regularly is Quality of Service (QoS) and more specifically L2 switch QoS. While the "Cisco AVVID Network Infrastructure Enterprise Quality of Service Design" SRND helped define best practice for configuring QoS in specific situations a thorough explanation of how QoS worked on the various platforms was lacking. This book does a wonderful job of not only picking up where the SRND left off but bringing in a lot of examples that apply outside the world of IP Telephony.
The first chapter of the book provides a good overview of QoS and its pieces and parts as they stand today. While some of the information might be a review, I would recommend that everyone still read this chapter because the authors do a wonderful job of creating a foundation for the rest of the book here. The section on Differentiated Services should be of specific interest because it is still a relatively new concept and a majority of the catalyst line is using DSCP under the hood.
The second chapter does a decent job of bringing QoS from Layer 3 down to Layer 2. This chapter does a good job of connecting the dots because a good portion of the QoS material out there is written specifically for Layer 3. Again, this chapter will be a review for many but still provides enough information that it is worthwhile to read.
Chapter three and four discuss functionality and configuration of QoS on what I would call legacy hardware. You might want to skip these chapters if you don't deal with these platforms. However if you still deal with these platforms, as I do, these chapters are a gold mine of information. The tables and diagrams in these chapters do a great job of explaining what features are available on each platform as well as how they function. I can not say enough about how valuable this information can be; these chapters alone would make me recommend the book.
Chapter five is a short chapter that introduces the Modular QoS CLI and is a good introduction if you haven't dealt with it before. This is probably something you can skim if you have just to make sure there aren't any features you weren't aware of.
Chapters six through nine go into great detail about the current line of catalyst switches and, as I said about chapters three and four, is invaluable. A minor drawback is that since the book was published before the introduction of the SUP720 and the CEF720 linecards so they are not included in the book directly. However, this concepts and information that is included in the book make it easy to understand these new linecards.
Whether you are pursuing a Cisco certification, deploying or managing a network with QoS on Cisco Catalyst switches this book has something for you. You will not be disappointed.
