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 […]
