You can replace certificates for a manager node or the manager cluster virtual IP (VIP) by making an API call.
After you install NSX-T Data Center, the manager nodes and cluster have self-signed certificates. It is recommended that you replace the self-signed certificates with a CA-signed certificate and that you use a single common CA-signed certificate with a SAN (Subject Alternative Names) list that matches all the nodes and VIP for the cluster. See Types of Certificates for details on the default self-signed certificates configured by the system.
If you are using Federation, you can replace Global Manager nodes, Global Manager cluster, Local Manager nodes and Local Manager cluster certificates using the following APIs. You can also replace the platform Principal Identity certificates auto-created for the Global Manager and Local Manager appliances. See Certificates for NSX Federation for details on self-signed certificates auto-configured for Federation.
Prerequisites
- Verify that a certificate is available in the NSX Manager. See Import a Self-signed or CA-signed Certificate.
- The server certificate must contain the Basic Constraints extension
basicConstraints = cA:FALSE
. - Verify that the certificate is valid by making the following API call:
