NX-OS and Cisco Nexus Switching Next-Generation Data Center Architectures The complete guide to planning, configuring, managing, and troubleshooting NX-OS in enterprise environments Kevin Corbin, CCIENo. 11577 Ron Fuller, CCIE No. 5851 David Jansen, CCIE No. 5952 Cisco Nexus switches and the new NX-OS operating system are rapidly becoming the new de facto standards for data center distribution/aggregation layer networking. NX-OS builds on Cisco IOS to provide advanced features that will be increasingly crucial to efficient data center operations. NX-OS and Cisco Nexus Switching is the definitive guide to utilizing these powerful new capabilities in enterprise environments. In this book, three Cisco consultants cover every facet of deploying, configuring, operating, and troubleshooting NX-OS in the data center. They review the key NX-OS enhancements for high availability, virtualization, In-Service Software Upgrades (ISSU), and security. In this book, you will discover support and configuration best practices for working with Layer 2 and Layer 3 protocols and networks, implementing multicasting, maximizing serviceability, providing consistent network and storage services, and much more. The authors present multiple command-line interface (CLI) commands, screen captures, realistic configurations, and troubleshooting tips-all based on their extensive experience working with customers who have successfully deployed Nexus switches in their data centers.
