today's data center networks. Troubleshooting Cisco Nexus Switches and
NX-OS is your single reference for quickly identifying and solving
problems with these business-critical technologies.
Three expert authors draw on deep experience with large Cisco customers,
emphasizing the most common issues in real-world deployments, including
problems that have caused major data center outages. Their
authoritative, hands-on guidance addresses both features and
architecture, helping you troubleshoot both control plane forwarding and
data plane/data path problems and use NX-OS APIs to automate and
simplify troubleshooting. Throughout, you'll find real-world
configurations, intuitive illustrations, and practical insights into key
platform-specific behaviors.
This is an indispensable technical resource for all Cisco network
