Like everything else in life, stuff can break in your NSX-T environment too. When that happens it’s important to understand how to get things back on track again. In the following blog articles I’m going through a couple of NSX-T failure scenarios and look at how to recover from them. As usual I’m doing this…
On August 30th 2019 I passed the brand new VMware Advanced Design NSX-T Data Center 2.4 exam. Let me tell you a little more about this exam and how I prepared for it. About the exam As far as I know 3V0-41.19 is the first ever design exam within the network virtualization certification track. A…

Hi and welcome back. We’re looking into the NSX-T data path and investigating different points at which we can capture network traffic. You may remember from part one that virtual machine “app01” (172.16.2.50) is trying to ping another virtual machine called “web01” (172.16.1.53), but it’s receiving “request timeout”. We’re trying to find out where in the data…
Welcome back! We’re looking at how to gain visibility at different points in the NSX-T data path. You may remember from part one that virtual machine “app01” (172.16.2.50) is trying to ping another virtual machine called “web01” (172.16.1.53), but it’s receiving “request timeout”. We’re trying to find out where in the data path we’re having…
Having good insight into the different components of a network communication path is key when managing networks. This goes for physical networks and for software defined networks. Today I’m having a closer look at the NSX-T data path and more specifically how to capture network traffic at different reference points in the NSX-T data path.…
Anybody working with NSX micro-segmentation knows the importance of monitoring application traffic and the associated distributed firewall rules. Today I just want to share a simple and quick way to increase visibility in the NSX distributed firewall logs. For this short article I’m using NSX-T 2.4.1 and vRealize Log Insight 4.8. vRealize Log Insight has…
Wether you like it or not, the API plays a significant role when installing, configuring, and managing an NSX-T environment. Sooner or later you will be facing tasks that either require you to use the API or simply are much faster to complete using the API. Luckily, with the right tools and some preparation, getting…
NSX tags on virtual machines often play a fundamental role in a NSX micro-segmentation security framework. Tags are used as the criteria for security group membership which in turn are used as source or destination in distributed firewall policy rules. Tagging virtual machines in NSX-T can be done in a number of ways. We essentially…

One of the first things to configure after deploying the NSX Manager nodes is backup. No NSX-T implementation should ever get configured let alone go live without a working backup (and restore) in place. Let’s have a look at how to set this up. Backup target NSX-T uses SFTP (TCP port 22) to transfer backup…
