So with the basic differences established, let’s make a comparison between TFTP and FTP with our copy options. However, TFTP is a simpler protocol and the server uses less memory when supporting clients and can be a scalable solution for applications such as IP Telephony. When you compare these protocol on that basic difference, you may conclude that FTP will always be the better option due to its reliability. TFTP uses User Datagram protocol which doesn’t establish a connection and therefore cannot guarantee that files to get to their destinations. FTP uses Transport control protocol, which provides reliability and flow control that can guarantee that the file will reach its destination while the connection is established. You also may have learned that these protocols are different based on how they deliver files to their destinations. You can see that it’s possible to copy to and from the device using TFTP and FTP. These options may vary and are derived from the IOS version running on the device. Note: This display shows some of the most common options.

As shown in example 1, you can see all the copying options that are available to use. When you look at the options with the copy command, you can see many different locations that your files can be saved. To begin, the Cisco Internet Operating System (IOS) has many options for saving files. Now, we're going to compare File Transfer Protocol (FTP) and Trivial File Transfer protocol (TFTP) for a Cisco router or switch. These protocols can be used for managing the files that exist for back up purposes. Recently we've been comparing using Telnet with Secure Shell protocol to allow remote access to a device such as a router or switch.
