When working with a colleague recently on an NSX-T 3.0 environment that utilises VDS 7.0 rather than N-VDS, we came across something which initially stumped me. If you were to try and create 2 Distributed Port Groups with the same name on the same vCenter the following error is displayed, […]
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 […]
Changing NSX-v controller passwords is a question which comes up quite a bit with customers. Often because the passwords chosen at deployment time are either too complex to type in on a VM console session, or on the other end of the spectrum, they were set to something easy to type […]
Whilst working with a customer recently, we encountered a situation recently where we were required to run a packet capture on a VCSA (vCenter Server appliance) version 6.0. Being a Linux appliance underneath, the tool to use is tcpdump, but by default tcpdump is not actually installed by default. There […]
On various engagements I am involved with, I often need to produce some code to add or delete objects from NSX-v. These objects in general are things like IP Sets, MAC Sets, Security Groups, Security Tags, Services, Service Groups, Security Policies and even deleting the FW rulebase itself. Until recently […]
So following on from my previous post (NSX-v: ESG Packet Capture), today we run through how to do a packet capture on one of your NSX Controllers. Why would you want to do this I hear you ask? Well I had a situation recently where I had some unexplained behavior […]
