Operation Manual – FTP and TFTP
H3C S9500 Series Routing Switches
Compared with FTP, another file transmission protocol, TFTP has no complicated
interactive access interface or authentication control, and therefore it can be used
when there is no complicated interaction between the clients and server. TFTP is
implemented on the basis of UDP.
TFTP transmission is originated from the client end. To download a file, the client sends
a request to the TFTP server and then receives data from it and sends
acknowledgement to it. To upload a file, the client sends a request to the TFTP server
and then transmits data to it and receives the acknowledgement from it. TFTP transmits
files in binary mode only.
The administrator needs to configure the IP addresses of TFTP client and server before
configuring TFTP, and makes sure that the route between the client and server is
reachable.
The switch can only function as a TFTP client.
