"NX-OS and Cisco Nexus Switching" discusses the operation, use, and configuration of the NeXt-generation Operating System (NX-OS) for Cisco data center products. The book describes the management and operations of the NX-OS including the following topics: " Introduction to Cisco NX-OS " Layer 2 Support and Configurations " Layer 3 Support and Configurations " Multicast Configuration " Security " High Availability " Serviceability " FCoE The book addresses the unique features of the OS such as configuration rollback, virtual device contexts, and high availability. In addition the book covers common layer 2 and layer 3 configurations for data center, including best practices. The book also covers multicast configuration, security features and high availability features. Each chapter points out helpful show commands as well as troubleshooting tips. The book includes loads of screen captures and sample configurations.
This is, as far as I can tell, the first "official" book about NX-OS and the Nexus switch line. It's been two years since the products were first released, and one of the more interesting topics in my opinion (Overlay Transport Virtualization) is mentioned only once, on page 2. I realize that as of right now, that feature isn't officially available, but two of the authors actually work for Cisco, and I would have thought that perhaps there would be something more than just a mere mention of this forthcoming feature.
It's got the usual issues with a first edition tech book: typos, errors, what-have-you. All pretty minor. I was struck more by how much the authors assume the reader already knows. Options are mentioned, but not really described. They assume you already know what this stuff is. I suppose in my case, that's probably true, but for a book that calls itself "The complete guide to...NX-OS in enterprise environments", it seemed to be less-than-complete.
And for some reason, the font size of the index is about twice that of every other Cisco Press book in my library.
