Troubleshooting Cisco Nexus Switches and NX-OS
Troubleshooting Cisco Nexus Switches and NX-OS
This is today's best single source for the techniques you need to troubleshoot problems with Cisco Nexus switches running the NX-OS operating system. Bringing together content previously spread across multiple sources and Cisco Press titles, it presents up-to-the-minute feature-level and architectural-level information that is indispensable for troubleshooting NX-OS software and Nexus hardware.
Three expert authors emphasise the Nexus NxOS-related problems you're most likely to encounter in real-world deployments, including issues that have caused major datacentre outages over the years. Drawing on their deep experience with large Cisco customers, they offer authoritative hands-on guidance for troubleshooting IGP, BGP, Nexus Fabric, FabricPath, VPC, VPC+, VLANs, STP, Port Channel, IPv6 and other IP services, EIGRP, OSPF, IS-IS, BGP, RPM, PBR, high availability, OTV, VxLAN, VxLAN BGP-EVPN, and much more. You’ll master state-of-the-art troubleshooting techniques for both control plane forwarding and data plane / data path problems, and gain essential knowledge of NX-OS APIs for automating the network and simplifying troubleshooting.
For each feature, key concepts are presented, followed by basic configuration and detailed troubleshooting techniques, complete with illustrations. Wherever appropriate, significant platform specific behaviours are described and analysed.
Troubleshooting Cisco Nexus Switches and NX-OS will be an indispensable technical resource for all network consultants, system/support engineers, network operations professionals and CCNP/CCIE certification candidates working in the datacenter domain.
