1.2.1 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 based 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.
TFTP-based file transmission can be performed in the following modes:
Binary mode, where executable files are transmitted.
ASCII mode, where text files are transmitted.
Note:
Before performing TFTP-related configurations, you need to configure IP addresses
for the TFPT client and the TFTP server, and make sure the route between the two
is reachable.
A switch can only operate as a TFTP client.
