One of my favorite products has just dropped a new version. vRealize Network Insight 3.8 (vRNI) has just hit the downloads and has a bunch of cool new stuff.

vRNI 3.6 introduced a public API with which you can do most of the day-2 operations. vRNI 3.7 didn’t bring any changes to the API, but 3.8 does. Below are the changes in the API version 1.1.0.

Fetching info in bulk

Version 1.0.0 had endpoints to grab information from entities (VMs, hosts, firewall rules, etc), but it was a bit tedious. You had to request a paged list of entities … Read more


This is going to be a short one! I received an interesting question from Sander Martijn about retrieving all IP routes from an NSX Edge. There is no API endpoint available in NSX to get the current routes and the only way this information can get retrieved is using the NSX Central CLI. You can easily see all routes on the Central CLI by using the command: show edge edge-id ip route.

PowerNSX has an Invoke-NsxCli cmdlet which executes the Central CLI with a specific query. Because of this, you can retrieve the routes with a PowerShell script and … Read more


This post is a part of my NSX SD-WAN by VeloCloud series to dive deeper into the acquisition of VeloCloud by VMware, late last year. In an earlier post, I explained the concepts behind the architecture of NSX SD-WAN and with this post, I will dive into the VeloCloud Orchestrator (VCO) to see what you need to configure to generate an SD-WAN network. Please note that the Orchestrator can be used to monitor and troubleshoot the SD-WAN as well, I will cover those topics in a future post.

NSX SD-WAN Architecture - Orchestrator

VeloCloud Orchestrator (VCO) – What is it?

The VCO is the management … Read more


NSX for vSphere 6.4.1 has been released and it brings a couple of good nuggets. Most of all, it is now compatible with vSphere 6.7 – so if you want to go to vSphere 6.7 and NSX was holding you back, start your upgrade engines!

HTML5 UI Extended

It fills me with joy to see this happening – 6.4.1 brings a bunch of new functionality to the HTML5 UI instead of the old vSphere-Client UI. The additions are:

  • Distributed Firewall Management
  • The Service Composer: Security Groups, Policies and Tags.
  • SpoofGuard Management
  • IPFIX Configuration & Flow Monitoring
  • Groups & Tags: all

This post is a part of my NSX SD-WAN by VeloCloud series to dive deeper into the acquisition of VeloCloud by VMware, late last year. I’ve had the privilege to play around with the virtual appliance for a couple of months with a physical appliance on the way. Expect more details in this series. 🙂

The upcoming chapters are building up the components that are in the VeloCloud portfolio and the components that you need to know.

Edge Appliances

An Edge Appliance is a physical or virtual appliance which is in the data path of your network traffic. It typically … Read more


Almost any organization that I’ve had the pleasure of talking with, uses Git either for code repositories where their developers work or for doing version control on their infrastructure systems. Git is an excellent version control tool and is widely used for both developers and also infrastructure configuration. This post goes into how to put the VMware NSX configuration into version control using Git.

Not all infrastructure components (server systems, network devices, etc) have a proper audit log on what happens in the configuration and who is doing what exactly. This is where version control can lend a helping hand … Read more


Over the last couple of months, Sander, Anne Jan and I have been working on a security whitepaper that lays out a practical implementation of zero trust while interfacing with a helpdesk system. In this case, OTRS.

It’s all about how engineers can get access to servers to perform maintenance, once your environment is properly micro-segmented. This whitepaper talks about the challenges you have when you’re micro-segmented and how you can resolve these challenges. Using OTRS as an example, this document lays out how to configure a help desk system like OTRS to interface with NSX to gain network … Read more
