To specify the SFTP idle timeout value (that is, the amount of time an SFTP connection can be idle before it becomes a candidate for termination), you can set the sftp.idle_timeout option. By default, the SFTP idle timeout value is 900 seconds.
Enter the following command: options sftp.idle_timeout timeout
timeout is an SFTP timeout value that is between 300s and 48h. You can specify the SFTP timeout value in seconds (s), minutes (m), or hours (h).
