Now that we have learned the theory in Microsegmentation with NSX-T (part 1: methodology), we can look at the application of this methodology in practice. Methodology in action So after all this, let’s see a little bit of this methodology in action. First of all, it is important to know which traffic is flowing in the environment. An excellent tool to help in this respect, would be vRealize Network Insight, but not every organization is able to use this, so…

After a number of blogs on network-virtualization, I thought it was time to start writing some blogs on another of the major three use cases: Security, through micro-segmentation. In my line of work most organizations where I implement NSX (first V and now T) are primarily interested in the security aspects of the product. In my presentations on NSX I usually use two pictures to show what security is like in most traditional environments. It looks something like this: (for…

I learned something today, which in hindsight is obvious. Hopefully this helps someone that runs into the same “strange” (but not so strange) behavior. I created the following topology today, to prepare for some NSX-T demo I am giving tomorrow: What I (among other stuff) wanted to show, was that routing between Test-Segments “D” and “E” and “A”, “B” and “C”, is completely distributed. So when VM’s from the different segments live on the same host, no physical hops are…

So apparently it has been 90 days since the deployment of NSX-T and therefor, time for the admin password to expire ;): Unfortunately, this doesn’t give you the opportunity to login and then change the password (a feature I would really appreciate), but a reset is necessary. In the online documentation (https://docs.vmware.com/en/VMware-NSX-T-Data-Center/2.4/administration/GUID-8816B842-2EC4-40A8-A618-F68DB29FABD2.html) the reset is done through a reboot into single user mode of one of the appliances and reset the password. However, in the online documentation one of the…

So, as you may know, I am from the Netherlands (or Holland, although technically I am not, but that is a different discussion ;)). So within my lab-environment I sometimes use Dutch as the language-setting, for instance within Firefox, the browser I use(d) to configure NSX-T. But this issue also occurs in Chrome. Within IE (although I only used that to test if it was affected by this ;)), the page doesn’t load at all. When I try to open…
