The system creates certificates required for communication between NSX Federation appliances as well as for external communication.

By default, the Global Manager uses self-signed certificates for communicating with internal components and registered Local Managers, as well as for authentication for NSX Manager UI or APIs.

You can view the external (UI/API) and inter-site certificates in NSX Manager. The internal certificates are not viewable or editable.

Note: Do not enable Local Manager external VIP before you register the Local Manager on the Global Manager. When NSX Federation and PKS need to be used on the same Local Manager, complete the PKS tasks to create an external VIP and change the Local Manager certificate before you register the Local Manager on Global Manager.

Certificates for Global Manager and Local Managers

After you add a Local Manager into the Global Manager , all certificates that authenticate the Local Manager for external and internal communication are copied into the Global Manager and trust is established between the two systems. These certificates are also copied into each of the sites registered with the Global Manager .

See the following table for a list of all the certificates created for each appliance using NSX Federation, and the certificates these appliances exchange with each other:
