If you’re ready to build a large network system, this handy excerpt from Ethernet: The Definitive Guide, Second Edition gets you up to speed on a basic building block: Ethernet switches. Whether you’re working on an enterprise or campus network, data center, or Internet service provider network, you’ll learn how Ethernet switches function and how they’re used in network designs.
This brief tutorial also provides an overview of the most important features found in switches, from the basics to more advanced features found in higher-cost and specialized switches.
Get an overview of basic switch operation, the spanning tree protocol, and switch performance issues
Learn about switch management and some of the most widely used switch features
Discover how a hierarchical design can help maintain stable network operations
Delve into special-purpose switches, such as multi-layer, access, stacking, and wireless access-point switches
Learn about advanced switch features designed for specific networking environments
Dive deeper into switches, with a list of protocol and package documentation
Charles Spurgeon is a senior technology architect at the University of Texas at Austin, where he works on a campus network system serving over 70,000 users in 200 buildings on two campuses. He has developed and managed large campus networks for many years, beginning at Stanford University, where he worked with a group that built the prototype Ethernet routers that became the founding technology for Cisco Systems. Charles, who attended Wesleyan University, lives in Austin, Texas, with his wife, Joann Zimmerman, and their cat Mona.
Joann Zimmerman is a former software engineer with a doctorate in art history from the University of Texas at Austin. She has written and documented compilers, software tools and network monitoring software, and been a creator of the build and configuration management process for several companies. The author of papers in software engineering and Renaissance art history, she currently she has multiple fantasy novels in process.
Ethernet Switches Authored by Charles E. Spurgeon and Joann Zimmerman Published by O'Reilly Media Book Review by Virginia Benedict
Do not expect to gain in-depth knowledge about Networks, Network Protocols, or Networking Standards for Switching and Routing packets and frames. However, as a beginner you can expect to be introduced to the very basics of Ethernet switching. Definitely, this sixty-six page divided into four chapters is a Primer or perhaps even a pocket guide for beginners. Some of these chapters are presented with basic illustrations
A final fifth chapter briefly touches on what the authors term "advanced switch features" such as traffic flow monitoring, sFlow, and Netflow, and PoE, The authors present the novice a good solid superficial glance at the roles switches serve in a network and how they differ from a router. They list the various types of switches and the purpose of each type.
The book seems to have been designed to get the appetite of an apprentice going. While switches play a critically central role in any network, routers are just as important and I do not get this message from this work.
At the end of the book, the authors provide an Appendix where they list but not cite some resources for additional reading. They also offer a brief glossary of related terms and acronyms.
If you are studying for your CCENT and would like to have a very simple overview, this book can serve as extra curriculum reading.
This book can be used as a pocket guide for beginners going for their CCENT
