  • Enable HTTPS Access to System: Enables SSL/TLS access to NSX Advanced Load Balancer GUI and REST API. When the option is enabled, the SSL Profile and SSL/TLS Certificate fields must be populated.

  • Redirect HTTP to HTTPS: When HTTP Access to System is disabled, enabling this option will automatically redirect administrators to the HTTPS interface for the web interface and API.

  • SSL Profile: Select an SSL Profile to complete the HTTPS Access. This profile is from Templates > Security > SSL Profiles, which is also referenced by SSL-enabled virtual services.

  • SSL/TLS Certificate: Select an SSL certificate from SSL/TLS Certificate drop-down menu to present to clients connecting to the web interface. RSA and Elliptic Curve (EC) are supported.

  • Allow Basic Authentication: Uses HTTP to prompt the NSX Advanced Load Balancer user for a username and password and to return the values to NSX Advanced Load Balancer for authentication and authorization.

The Client Management Access to NSX Advanced Load Balancer Controller lists four different client types that are authorized system users:

  1. SSH Clients

  2. CLI Shell Clients

  3. External HTTP(S) Clients

  4. External SNMP Clients
