TFTP Port, Port for TFTP, SolarWinds TFTP Server

TFTP otherwise known as Trivial File Transfer Protocol is a very simple protocol that functions using UDP (User Datagram Protocol), and the TFTP Port is Port 69. This TFTP Port 69 is used in the communications between a Host and a Server. The communication is such that a Host sends a request for a file to the Server, and the Server responds with the file, but there is no connection established before the sending and receiving of the data. Packets are sent with no form of acknowledgment or confirmation.

TFTP with UDP provides connectionless communications between Hosts and is most commonly used where File Transfer Protocol (FTP) or Secure File Transfer Protocol (SFTP) is not necessary. Now, FTP and SFTP are secure and more robust file transfer protocols but TFTP is not. Based on this, it is not recommended to use TFTP in moving files or sensitive information on the internet.

Also, TFTP does not have certain features that you find in more advanced file transfer protocols. It is simple and operates with low overhead to carry out file transfers faster and more efficiently. Its small size, and its simplicity, are what make it suitable for use in situations where resource usage will not be a concern. Typically, TFTP is applied in situations such as transferring configuration files, backing up of configuration files, firmware updates, et cetera.

How to transfer files using SolarWinds TFTP Server

Using SolarWinds Server for file transfers is a very easy and straightforward process. When you launch it, it automatically picks the IP Address of your PC. If you want to change the IP Address, you can as well do so.

Using a Cisco router as an example, we can backup the router’s config onto SolarWinds TFTP Server. To do this, we first of all ensure that our Cisco router and our SolarWinds TFTP Server are pingable. Connectivity between them is the most important step before a backup can take place. When this is ensured, simply SSH or console into the device to be backed up. In our example, the IP Address of the router to be backed up is and the SolarWinds TFTP Server is located at Now, we type each config one after the other on each line as shown in the picture below.

Do note that you can leave the Destination filename as it is, or you can choose a Destination filename as you want by typing it after [router_office_1-config]. After the file has copied successfully, you should see it in your C:\TFTP-Root folder.

This is as simple as it gets to using SolarWinds TFTP Server for file transfers or taking backups. Furthermore, this entire process is the same if you want to try it out with another TFTP Server. For example, Tftpd64. This is another free and open-source TFTP Server and Client. It features DHCP, DNS, SNTP, Syslog, and TFTP.
