When you add a host to the vCenter Server inventory, you can assign a license key to the host.

You must have a communication channel through a firewall before you add a host.


Verify that the edition of the license key you assign to the host matches the currently configured features and resources. Otherwise, you cannot assign the license key.


Click Inventory in the navigation bar.


Expand the inventory as needed and click the appropriate datacenter, folder, or cluster.


Right-click the datacenter or cluster and select Add Host.


At the prompt, assign an existing vSphere license key or add a new vSphere license key.
