# SSDP Configuration Parameters

This section describes the Simple Service Discovery Protocol (SSDP) configuration parameters that enable Coordinator to find SSDP-enabled Controllers.

When you enable SSDP in your Controllers, Coordinator can automatically detect the Controllers in your network. You can use the GetControllers action to list the registered and discovered Controllers. This option allows you to find the details for Controllers that you might want to register without having to know the host and port details.

NOTE: Coordinator cannot automatically send actions to discovered Controllers. You must still register the Controllers by using the AddController action.

If you do not enable SSDP in your Controllers, you must add the Controllers manually to Coordinator by host and port. Similarly, if you are using GSSAPI authentication in Micro Focus Coordinator Reference and your Controllers, you cannot use SSDP and must add the Controllers manually to Micro Focus Coordinator Reference by host and port.

For more information, refer to the Controller Reference.
