Revision notes from VMware Network Virtualization Fundamentals Course

VMware released a free course around Network Virtualization Fundamentals, which maps to the first steps on the ladder for all things NSX. It is also recommended by VMware to take the course before taking on the VCA-NV.

I urge anyone looking into NSX to take this course, you can’t argue with the price after all!!! Secondly, although there are many NSX posts online name, Brad Hedlund has some of the best posts in my opinion.

Check the NSX-Link-O-Rama aswell.

And finally, the NSX Compendium over at Network Inferno

Below are my notes I took whilst going through the course.

The Basics
Virtual switch
  • Ports organised into port groups
  • Uplinks connect virtual switch to physical network
  • Connections to support virtual infrastructure

Virtual standard switches – configuration per host, therefore needs to be replicated exactly to all hosts

  • Port groups
  • VMkernel Ports
  • Uplink Ports
  • Policies at virtual switch level can be over-ridden  at port group level
  • VLAN’s set at port group level and VMKernal Port level only
  • No support for things like STP, as virtual switches cannot be connected to one another, nor do they learn MAC addresses.

VMware NSX – Just an introduction

With my background in Networking and Virtualisation, VMware’s NSX is something which interests me deeply, as such I’ve attended a handful of sessions online, and also at the UK VMUG where Chris Whal presented on the subject.

Here’s my own interpretation of this new technology.

What is NSX?

Its software-defined networking, you don’t need to buy any hardware to implement it, although you do need a running VMware environment.
