NSX-v 6.2 was released last week (Release Notes) and one of the features mentioned in the release notes is the Communication Channel Health feature. Show health of the communication channels: NSX 6.2.0 adds the ability to monitor communication channel health. The channel health status between NSX Manager and the firewall […]
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) […]
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 […]
When using the CLI of an Edge Services Gateway there are some commands that can only be run from privileged mode. This is similar in fashion to the Privileged EXEC mode in Cisco IOS devices, and also the commands to turn on and off privileged mode are identical. To turn […]
One of the features of NSX-v is the ability to create a Layer 2 VPN between 2 NSX-v Edge Services Gateways (ESG from now on). But what happens if there is no NSX-v at the destination where you would like to extend your Layer 2 network. As of NSX-v 6.1.0 […]
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 […]
