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.
Â
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.
Â
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.
- Learn how Cisco NX-OS builds on and differs from IOS
- Work with NX-OS user modes, management interfaces, and system files
- Configure Layer 2 networking: VLANs/private VLANs, STP, virtual port channels, and unidirectional link detection
- Configure Layer 3 EIGRP, OSPF, BGP, and First Hop Redundancy Protocols (FHRPs)
- Set up IP multicasting with PIM, IGMP, and MSDP
- Secure NX-OS with SSH, Cisco TrustSec, ACLs, port security, DHCP snooping, Dynamic ARP inspection, IP Source Guard, keychains, Traffic Storm Control, and more
- Build high availability networks using process modularity and restart, stateful switchover, nonstop forwarding, and in-service software upgrades
- Utilize NX-OS embedded serviceability, including Switched Port Analyzer (SPAN), Smart Call Home, Configuration Checkpoint/Rollback, and NetFlow
- Use the NX-OS Unified Fabric to simplify infrastructure and provide ubiquitous network and storage services
- Run NX-OS on Nexus 1000V server-based software switches
