You can modify the API service properties of the NSX Manager cluster, such as TLS protocol version, cipher suites, and so on.
The following procedure explains the workflow of running the NSX API service calls to disable the TLS 1.1 protocol, and to enable or disable the cipher suites in the API service configuration.
For a detailed information about the API schema, example request, example response, and error messages of the NSX API service, you must read the NSX API Guide.
Procedure
Results
The API service on each NSX Manager node restarts after it is updated using the API. There might be a delay of up to a minute between the time the API call completes and when the new configuration comes into effect. The changes in the API service configuration are applied to all the nodes in the NSX Manager cluster.
