Introduction to TFTP
Trivial file transfer protocol (TFTP) is well suited to the file transfer between a server and a client that do
not need complex interaction.
In TFTP, the transmission is initiated by the client. When downloading a file, the client sends a read
request packet to the TFTP server, receives the data packets from the server, and sends the ACK to the
server. When uploading a file, the client sends a write request packet to the TFTP server, then sends
the data packets to the server, and receives the ACK from the server. The TFTP transmission files have
two forms, i.e., binary for program transmission and ASCII for text transmission.
Following is the updating procedure described taking the switch working as a TFTP Client as an
example.
