The much–anticipated update to the bestselling book on LAN switching
Since the publication of the first edition of The Switch Book seven years ago, LAN switching has witnessed significant changes, particularly in the areas of network layers, Ethernet, fast Ethernet, segmenting LANs, layer 3 switching, layer 4 switching, and multi–layer switching, to name just a few. With this updated guide, you′ll discover the latest capabilities of LAN switches and get in–depth coverage of the abstract engineering principles behind switch operations in addition to the practical application of those principles in commercial products.
Coauthored by an innovator who has been at the forefront of networking technology for more than two decades, this unique resource begins by laying the foundation of the core technologies underlying LAN switch design, including network architecture, addressing, LAN technology, and LAN standards. Building on those fundamentals, the book goes on to investigate the many advanced features, as well as the possibilities, that exist in modern switches. From there, you′ll dive into the technical details of transparent bridges as they are used between similar and dissimilar technologies. You′ll learn that, along with the performance advantages that are offered by switches, comes an increase in features, options, and complexity.
With more than forty percent new and updated material, this second edition of The All–New Switch Book explains:
The problems of link congestion that arise from the deployment of LAN switches
How switches and end stations can use a group of independent LAN segments as if they were a single link
Security concerns that environments need to be aware of, and how to prevent attacks
The concepts and operation of source routing in both end stations and bridges
The various uses for Virtual LANs (VLANs) as well as the key concepts employed by devices that implement VLAN capability

Customer Reviews
This book has every little detail you need to understand everything network switching. It explains the history of where the switch came from, and how the industry standards have shaped the network hardware that we see today.
It then goes on to give you valuable information about switching methods, design and application usage, network security, and much more! It is the ultimate book on network switching, and it has helped me progress through our business rapid-growth period.
The book is well written, no doubt. The author understands what is difficult in making a high performance switch, and how different features interact. Furthermore, the book deals with a multitude of standard, technologies, so that the the manager of a larger net better can understand, troubleshoot and plan his network.
This book is definitely too much for the person wanting to know what a switch is. That is not the audience. I can recommend the book for the network professional, especially for those who start as practitioners, and need a better theoretical underpinning. I do not meen 'formal language' theoretical, but who wants to understand the 'why is it like this' in switching technology.
The only reason I do not give it 5 stars, is that the book covers more than many users ever will need. The authors do explain challenging concepts in a good way, so if you like me really want to get it - get this book.
But I've found what seems to me like an excessive number of typos in this new book. Mine is labeled as a Second Edition on the copyright page, but the little countdown numbers (which I think show the printing) go all the way from 10 down to 1 (so maybe it's a first printing).
They give an email to send errata to (and I've sent several - a quick check on outlook shows 7) and nobody has ever responded, so I'm not sure if they are really interested in fixing the problems or not.
In some cases, there were diagrams that were correct in the original book (at least the "books 24/7" version we have available online here), but are incorrect in the new book. (For example fig 9-8 on p. 376 has the Aggregator recieve queue (on the right) labeled as an Aggregator Transmit queue. Similar errors on page 372 and 373 in the Link Aggregation stuff. It looks like when they went to update to the new book, they failed to get the latest graphics files from the old book. There are also several internal references that don't match.
There are also section number references that are wrong (Page 36 has a reference to section 1.1.7.3 that should be 1.1.9.3, for example)
As far as I can tell, none of the typos are *real* serious, but I found the diagram errors (which went wrong from the original book) particularly troubling, as well as the lack of response from their email support address.
Apparently this review triggered a sideband contact to the author, who emailed me about the errors. Email was apparently piled up on the errata email address. They are working to make the corrections.
Listmania!
