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. I’ll be using the 5500 series as my example and covering the basics without getting into features such as fibre channel, VSANs and that sort of thing. cisco. 0(3)4(1) on the 9000 platforms. As stated in the configuration guide,"A virtual port channel (vPC) allows links that are physically connected to two different Nexus switches to appear as a single port channel by a third device. So what is the solution for Nexus vPC and non-vPC VLANS on the same platform (hybrid)? vPC configuration is made up of three main components, the vPC Peer Keepalive Link, the vPC Peer Link, and the vPC Member Ports. cisco nexus vpc configuration example
