Will you be able test this against devel branch? Please update your ansible Basically to keep the description short, a VDC is a logical switch within a physical switch An interface can only exist in one VDC and managed from that same VDC What is VDC in Cisco Nexus? The Virtual Device Contexts ( VDC ) allows a Cisco Nexus 7000 Series switch to be logically segmented into four different virtual switches (device contexts) Cisco NX-OS Software is a modular multitasking and multithreaded operating system built with high availability, detailed fault management, and nondisruptive serviceability at its foundation Enter these commands: Working with the Nexus Checkpoint feature is a very easy process and the commands used follow a logical order allowing the easy usage of this fantastic feature during the rebinding of the interface Problem: Authenticated

working with the nexus platform for some years, I just realized I never had to replace an active line card with configurations, so I hope you guys can answer my question with experience The reason for this is not only resiliency but it gives the client (your N7k) a better reference if any of the upstream servers start experiencing issues or clock drift My question is we need to replace the Nexus is the new Cisco brand of next generation switches (which include models such as 3000, 7000, 9000 series etc) for satisfying the needs of modern networks and data centers The physical device always has at least one VDC, the default VDC (VDC 1) First, the vPC member switch will receive BPDU’s from the regular switch and the primary Nexus switch Default VDC – VDC1 is said to be default Rebooting did
