You can install and assign an NSX for vSphere license after NSX Manager installation is complete by using the vSphere Web Client.

Before purchasing and activating an NSX for vSphere license, you can install and run the software in evaluation mode. When run in evaluation mode, intended for demonstration and evaluation purposes, NSX components are completely operational immediately after installation, do not require any licensing configuration, and provide full functionality for 60 days from the time you first activate them.


Log in to the vSphere Web Client.


Click Administration and then click Licenses.


Click the Solutions tab.


From the drop-down menu at the top, select Assign a new license key.


Type the license key and an optional label for the new key.


Click Decode.

Decode the license key to verify that it is in the correct format, and that it has enough capacity to license the assets.


Click OK.

Obtain and install an NSX for vSphere license within the evaluation period.
