TFTP Configuration
Introduction to TFTP Compared with FTP, TFTP (trivial file transfer protocol) features simple interactive
access interface and no authentication control. It simplifies the interaction
between servers and clients remarkably. TFTP is implemented on UDP. It transfers
data through UDP port 69. Basic TFTP operations are described in RFC1986.
TFTP transmission is initiated by clients, as described in the following:
■ To download a file, a client sends read request packets to the TFTP server,
receives data from the TFTP server, and then sends acknowledgement packets
to the TFTP server.
■ To upload a file, a client sends writing request packets to the TFTP server, sends
data to the TFTP server, and then receives acknowledgement packets from the
TFTP server.
