While NSX 6.2.x has been out for a while now, most people should be aware of the newly introduced feature called the Central CLI. I won’t go into the details of what the Central CLI is, as you can read about it on Brett Draytons blog (link). What I do […]
I was onsite implementing NSX-v for a customer, and part of the installation in this environment requires that we allocate the VTEP pnics to the VXLAN transport VLAN. To do this I had to liaise with the Network Operations guy. After laying it out for him that although these VTEP […]
Have you ever had the problem of working on a unstable network connection and your network drops out. Well this happened to me this morning, but whilst it happened, I was actually connected to my NSX Manager via SSH and in configuration mode. When my network connectivity returned (4G) and […]
One of the main reasons for customers wanting to implement NSX for vSphere is the fact there is a RESTful API which can be leveraged to drive the whole system. In a standard NSX-v installation, by default, the only account that has API only privileges (and no vSphere Web Client privileges) […]
Due to a recent lab rebuild, I needed to manually remove the NSX VIBs that were installed on my ESXi host, and thought I would document the process so I can remember it in the future. Removing the NSX VIBs from a host manually does not remove the configuration stored […]
Whilst working on a little side project of mine, I wanted to be able to submit a REST API call against a NSX Manager. At first I was just going to use shell_exec to execute one of my python scripts, but after a bit of investigation, I found that I could use the […]
Following on from my last post about the NSXRAMLCLIENT, I decided to setup an Ubuntu machine dedicated to being able to run the NSXRAMLCLIENT in my home lab. Using my own instructions that I had written previously to get it up and running on my OSX 10.10.5 machine, I came across a […]
Up until now, my programmatic interactions with the NSX API have all been hacked together based on the NSX API Guide, due to the lack of a specific NSX API scripting interface. For typical vSphere scripting, there has been PowerCli and also pyvmomi and I am sure a few […]
When working with the Service Composer in NSX-v, by default, when a firewall rule is created in a Security Policy, the firewall rule, when applied, uses the default Applied To value of Distributed Firewall. This means that even though the firewall rule is part of a security policy which is then applied to a specific security group, the rule would be pushed down to every vNIC within the clusters that have been prepared for NSX DFW capabilities and have the firewall enabled. One of the new features introduced in NSX-v 6.2 […]
One of the new features in NSX vSphere 6.2 is the introduction of new IP discovery mechanisms. The official release notes mentions this as follows: New IP address discovery mechanisms for VMs: Authoritative enforcement of security policies based on VM names or other vCenter-based attributes requires that NSX know the IP […]
