Specify the FTP server's control connection port.
The FTP server will listen for incoming logins on the control connection port number.
This port number must not conflict with other port reservations. Both the port number you specify and port number - 1, are reserved for the FTP server. Therefore, other applications must not already have reserved these ports.
If another application has already reserved the ports, you will be asked if you want to negate the reservation for the other application and proceed with your FTP server's port reservation request.
If the port is already reserved for another FTP server, you will be asked if you want to bind an IP address to this FTP server's port reservation. If you decide to bind an IP address, then your server will connect only to clients using this bind IP address when logging in.
To see all port reservations, return to the IBM TCP/IP Configuration Demo for z/OS main customization panel and go to the Basic Settings task.
