Cisco IOS in a Nutshell (In a Nutshell
(OReilly)) by James Boney
Must For Cisco Network Professionals
Three cheers for the Nutshell format! There may be no better printed style
for command-line environments, like the Internetwork Operating System
(IOS) that runs on Cisco Systems routers. Cisco IOS in a Nutshell
documents the most important bits of the frequently arcane IOS command
line from aaa accounting to write, thereby providing a valuable resource to
everyone who works with IOS. The reference section--which makes up
about 60 percent of this book--summarizes each command (again, theyre
not all covered, but the ones that arent are pretty obscure) with a
statement of its scope (global, interface, line, or whatever), followed by
generalized syntax summaries in the style of Unix man pages (these
indicate the legal combinations of switches and parameters). Then, a
detailed discussion of each switch and parameter clarifies what each is for.
The whole reference section is alphabetical, with lettered dark boxes on
the pages outer edges that are easy to scan while flipping pages rapidly.
Prior to the reference section, the author explains how the IOS interface

refers to and controls aspects of routers, such as lines and interfaces. He
does a great job of it, too--you could do far worse than to read his
explanations before going to work under IOS for the first time. The other
great value of this early section is in the authors discussion of how to
configure a new router by bringing interfaces, data-communication
protocols (like TCP/IP), routing protocols (like Border Gateway Protocol, or
BGP), and services like Domain Name Service (DNS) online. This book is
a tremendous value for Cisco engineers. --David Wall Topics covered:
How to configure a Cisco Systems router with the Internetwork Operating
System (IOS). The most popular commands are documented, and theres a
tutorial section that familiarizes readers with the Cisco way of thinking
about a routers work. The author uses IOS 12.x as his baseline, though
users of older versions will find his work valuable.
Personal Review: Cisco IOS in a Nutshell (In a Nutshell
(OReilly)) by James Boney
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.
