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 […]
When working with a customer recently to install NSX-v into a lab environment, we were faced with hosts which would fail when we went through the Host Preparation steps to install the NSX VIBs. As it turns out, it wasn’t the usual problems of incorrect DNS or a firewall causing issues but […]
Operating and troubleshooting a NSX-v environment can sometimes be a daunting task, especially if the customer had the environment setup by an external party (ie. VMware PSO or a VMware Partner). And so over the past few weeks, VMware have released 2 pieces of collateral which I am finding answer a […]
Recently when doing some performance testing with a customer, we wanted to have the ability to bulk create a number of DFW rules. By leveraging some python scripting and the NSX-v API, I came up with a flexible and re-useable script which can be used to create a new section […]
For those who have used the NSX vSphere REST API, you will know that with every API call you are required to send the following in the headers: Content-Type application/xml Basic <base64 encoded credentials> So if you have an OSX machine, you can leverage openssl (which is installed by default) […]
