For more secure transfer of PMN files, you can enable Secure File Transfer Protocol (SFTP).
Configure SFTP in the site_vars file by setting ARRIS_CMTS_RX_MER_FTP_MODE to one of the following values:
- secure — Always use SFTP to transfer files.
- hybrid — Attempt to use SFTP,
but in the case of failure, revert to FTP.
This value is the default if not specified.
- ftp — Always use FTP.
SFTP uses the configured SSH port, typically port 22. You must also identify this port in the site_vars file by setting ARRIS_CMTS_RX_MER_SSH_PORT.
For more information, refer to site_vars file definitions.
