Cisco routers are everywhere that networks are. They come in all sizes, from inexpensive units for homes and small offices to equipment costing well over $100,000 and capable of routing at gigabit speeds. A fixture in today's networks, Cisco claims roughly 70% of the router market, producing high-end switches, hubs, and other network hardware. One unifying thread runs through the product line: virtually all of Cisco's products run the Internetwork Operating System, or IOS.

If you work with Cisco routers, it's likely that you deal with Cisco's IOS software--an extremely powerful and complex operating system, with an equally complex configuration language. With a cryptic command-line interface and thousands of commands--some of which mean different things in different situations--it doesn't have a reputation for being user-friendly.

Fortunately, there's help. This second edition of Cisco IOS in a Nutshell consolidates the most important commands and features of IOS into a single, well-organized volume that you'll find refreshingly user-friendly.

This handy, two-part reference covers IOS configuration for the TCP/IP protocol family. The first section includes chapters on the user interface, configuring lines and interfaces, access lists, routing protocols, and dial-on-demand routing and security. A brief, example-filled tutorial shows you how to accomplish common tasks.

The second part is a classic O'Reilly quick reference to all the commands for working with TCP/IP and the lower-level protocols on which it relies. Brief descriptions and lists of options help you zero in on the commands you for the task at hand. Updated to cover Cisco IOS Software Major Release 12.3, this second edition includes lots of examples of the most common configuration steps for the routers themselves. It's a timely guide that any network administrator will come to rely on.

Just Useful! - 2008-11-20

Depending on what you wish to get you will judge this book.
I was after a quick reference just to check various switches in different IOS commands and to quickly work out how they can be utilized - It did the job! however there some caveats :
The version of IOS used by the Author probably is 12.1 or even earlier , some commands have been changed and some configurations are no longer valid. For instance in order for static RP to work you have to configure the RP itself to make things happen but the nice example in the Multicast chapter does not have this command (since it was not mandatory prior to 12.2). Or in the SNAT section, there is a fantastic example but for a first timer it's pretty much useless because most of Stateful NAT commands are required to be changed in the latest IOS versions. Anyway, I strongly believe that by developing a new edition of this valuable book it still could be one of the best IOS resources.
HTH,

This is a good reference book, but don't count on it to teach you how to set up a Cisco device or any networking. Even though it is fairly current, I have found a few differences between it and IOS 12.4 T.

Another good in job reference book - 2008-02-28

this is another all in one book that i have, the other one is cisco ios cookbook. what i found that this book is very good after using it for some time, and also the writing style makes me easy to understand it very well.

i like the part where the author give comment on each line after a command to tell the reader what does that command do.

this book cover wide variety of things, and honestly i haven't read and tried all of the parts, but from what i have read and tried, this book gives very good detail in setting up tunnel and its security, it did help me understand how to set it up from scratch while i didn't know about it at all before.

in qos part, this is why i give this book 4/5, it just tell you briefly what each type of qos method does what it doesn't really give you an example of working configuration. i would like to see the author give an example from a real life configuration, suggestion to choose which type that we should use for particular case or even maybe combining few different type.

another suggestion is maybe to update the book with more information, and more commands that newer ios supports.

my recommendation is to get this book along with cisco ios cookbook, i am pretty sure it will cover the part where this book is missing and vise versa. you might also find this book is easier to read and understand than cookbook as well.

Must for Cisco Network Professionals - 2007-09-20

I bought this book for my Master's research paper on Cisco IOS.

I have found this book to be a good source on IOS's architecture. It has approximately 120 pages dedicated to general internetworking fundamentals such as differences betwen RIP, OSPF, and EIGRP.

The rest of the book is dedicated to IOS commands and proper syntax usages. This is a great reference book and good overview of networking concepts.

Great!!!!! - 2009-05-29
