protocolDetails

The protocol settings that are configured for your server.

Avoid placing Network Load Balancers (NLBs) or NAT gateways in front of Transfer Family servers, as this increases costs and can cause performance issues, including reduced connection limits for FTPS. For more details, see Avoid placing NLBs and NATs in front of Transfer Family.

• To indicate passive mode (for FTP and FTPS protocols), use the PassiveIp parameter. Enter a single dotted-quad IPv4 address, such as the external IP address of a firewall, router, or load balancer.

• To ignore the error that is generated when the client attempts to use the SETSTAT command on a file that you are uploading to an Amazon S3 bucket, use the SetStatOption parameter. To have the Transfer Family server ignore the SETSTAT command and upload files without needing to make any changes to your SFTP client, set the value to ENABLE_NO_OP. If you set the SetStatOption parameter to ENABLE_NO_OP, Transfer Family generates a log entry to Amazon CloudWatch Logs, so that you can determine when the client is making a SETSTAT call.

• To determine whether your Transfer Family server resumes recent, negotiated sessions through a unique session ID, use the TlsSessionResumptionMode parameter.

• As2Transports indicates the transport method for the AS2 messages. Currently, only HTTP is supported.
