API-Portal accepts port connection requests as soon as it receives them. If you want to temporarily prevent API-Portal from accepting requests on one of its ports, you can disable that port. This action blocks incoming requests from reaching the API-Portal server. When a port is disabled, clients receive an error message when they issue requests to it. Later, you can enable the port. If you stop and restart API-Portal, the port remains disabled until you enable it. Disabling a port is a convenient way to eliminate developer access to an API-Portal once it goes into production.
