FTP support is needed:
Whether it be a Third Party or SolarWinds developed tool.
Example would be a Cisco ASA 5505:
SCP and SFTP are not valid transfers
TFTP and FTP only
TFTP is not secure, while FTP communication is secured with SSH encryption
FTP traverses via TCP and is reliable, where TFTP is UDP and is not reliable
Although FTP is sent in plain text and is not as secure as SFTP/SCP it is preferred over TFTP when SFTP/SCP is not an option.
