This book is intended for any beginning user of the Cisco IOS software. Advanced users will also find this reference valuable because of the many examples and tips for using common IOS features.
We assume that the reader has some general background in the various types of internetworking equipment, such as hubs, bridges, switches, and routers. Coverage of the intricate details of these types of equipment is outside the scope of this book, but we review them briefly with respect to the Cisco IOS software. Likewise, comprehensive introductions to TCP/IP, AppleTalk, and IPX are left to the several fine texts already available, some of which are referenced at the end of each chapter. Instead of duplicating existing references on specific internetworking equipment and protocols, this book concentrates on the use of these technologies by products that run the Cisco IOS software.
