Plan, configure, operate, and troubleshoot Cisco's advanced NX-OS in even the most complex enterprise environments bull; bull;Accelerates the NX-OS learning curve, demonstrating how NX-OS works and how to use it to configure advanced Nexus switches in data center environments. bull;Offers indispensable troubleshooting guidance directly from Cisco enterprise consultants. bull;Cisco's Nexus switches and new NX-OS operating system are expected to become the de-facto standards in the coming years. Cisco's Nexus switches and new NX-OS operating system are expected to become the de-facto standards for data center distribution/aggregation layer networking in the coming years. NX-OS builds on Cisco IOS to provide powerful features that are becoming increasingly crucial to efficient data center operations. NX-OS and Nexus Switching is the first comprehensive guide to the new capabilities that make NX-OS so indispensable in enterprise environments. In this book, three Cisco enterprise consultants cover every facet of deploying, configuring, operating, and troubleshooting NX-OS in the data center. The authors discuss NX-OS's similarities and differences with IOS, and thoroughly review its key enhancements for high availability, virtualization, In- Service Software Upgrades (ISSU), and security. They systematically cover both Layer 2 and Layer 3 support and configuration best practices; multicasting; serviceability; and FCoE. They also present never-before-published problemsolving guidance based on their own extensive experience working with leading-edge adopters.
