VMworld 2015 presentation recordings have been published

..which includes the session on NSX Troubleshooting methodology that I presented.

To find my session called “NET5488 – Troubleshooting Methodology for VMware NSX”, search for “NET5488”. Both US and Europe versions are available.

In this session, I walk through how NSX-v’s VXLAN-based logical switching works, what commands you can use to see what’s happening under the covers, and how to make sense of what you’re seeing. This should provide a good base for your troubleshooting practice.

(Hat tip to ‪@ericsiebert and ‪@scott_lowe‬ for the info that sessions are now online, free for all)

From the dept of the knowledge arcane: NSX-v with nested ESXi

Nested ESXi is a staple of resource-strapped labs. There is, however, a little something that’s worth keeping in mind when using NSX-v / VXLAN.

My presentation from VMworld 2015

#NET5488: Troubleshooting Methodology for VMware NSX (for vSphere, v6.2):

#NET5488 – Troubleshooting Methodology for VMware NSX – VMworld 2015 from Dmitri Kalintsev

I designed the pack to be read, so hopefully you find it useful without the recording. For those who have attended VMworld, both US and Europe sessions were recorded. You should be able to watch them on vmworld.com.

Not sure which one (US or EU) went better, to be frank. 🙂

NSX-v under the hood: VXLAN ARP suppression

When troubleshooting, it’s important to know how the system is supposed to work, so that one can tell whether the currently observed behaviour is normal or not.

This post covers VXLAN ARP suppression in NSX-v.
