Use the TLSMECHANISM statement to specify whether TLS is implemented by AT-TLS or by FTP. AT-TLS is the preferred method for implementing TLS.
- Server
- This setting specifies how TLS security is implemented on the server host. This statement is valid for FTP servers if EXTENSIONS AUTH_TLS is specified.
- Client
- This setting specifies how TLS security is implemented on the client host. This statement is valid for FTP clients if SECURE_MECHANISM TLS or SECURE_MECHANISM SSL is specified.
