CISCO IOS in a Nutshell
Publisher: O'Reilly Media
Final Release Date: December 2001
Pages: 608

Routers are the glue that holds the Internet together, and Cisco Systems--holding roughly 70% of the market--is the most prominent router manufacturer. Cisco's routers come in all shapes and sizes and almost all of them, from the smallest to the largest, run the IOS operating system. IOS is an extremely powerful and complex operating system, with an equally complex configuration language. There are many commands, with many options, and if one thing is configured incorrectly, the entire company could find itself offline.Cisco IOS in a Nutshell covers IOS configuration for the TCP/IP protocol family. The book is divided into two parts: the first part includes chapters on the user interface, configuring lines and interfaces, access lists, routing protocols, and dial-on-demand routing and security; the second part is a classic O'Reilly-style quick reference to all the commands that you need to work with TCP/IP, including the lower-level protocols on which it relies, and lots of examples of the most commonly encountered configuration steps for the routers themselves.

Cisco IOS in a Nutshell Review

By Hans-Georg Hettwer

from Undisclosed

Comments about O'Reilly Media CISCO IOS in a Nutshell:

Recommendable book for all beginners on Cisco routers.

Many detailed example configurations are making this book valuable

and the way it is written makes it enjoyable to read.

What I am missing is a chapter for beginners. Because when you are not familiar with

with Ciscos platform and functionllity concept is it difficult to find out what function

is on your router and which functionallity is not but can be added however.

Cisco IOS in a Nutshell Review

By John Herraghty

from Undisclosed

Comments about O'Reilly Media CISCO IOS in a Nutshell:

CISCO IOS is essentially an ad-hoc effort that lost logical form some years ago. But IOS is widely known, and is thus a de facto router config standard. For some semblance of logic in the ad hoc jumble, this book will shine a light. I would recommend it for both beginners and experienced operators. It provides a lot of glue to hold information together. CISCO IOS on line help is cryptic at best, but the command line reference covers command by command with excellent configuration examples. When you are away from a router for a few months, and then have to go back to doing a routing project, this is a simple and timesaving way to verify your configs for the basic stuff.

Sure, some subjects could have been covered in more depth, but it isn't an encylopaedia, just a desk reference. I much prefer this book which is geared to making things work, than the CISCO books which are geared to passing exams. Use the CISCO web site to review in depth technology configurations. Use this book to review before you configure. Don't show up on a customer site without it.

Cisco IOS in a Nutshell Review

Comments about O'Reilly Media CISCO IOS in a Nutshell:

Some of the good things are:

1. The Special Topics chapter that discusses the differences between IRB, CRB

and what BVI's are used for. Ive never found a better description.

2. The chapter on ATM/Frame Relay. I especially liked the definitions of ATM

encapsulation, aal5snap, aal5mux, aal5nlpid. Excellent. I liked the

discussion of LANE as well.

3. The line command chapter. Cleared up some things for me. Thanks.

A couple of the bad things are:

1. Mutlicasting should be better covered.

2. In the command reference It would be nice to know what IOS image the

command is supported in and on what platform.
