Configuring FTP Server Parameters
You can use the following commands to configure the connection timeout of the
FTP server. If the FTP server does not receive a service request from the FTP client
for a period of time, it will cut the connection to it, thereby avoiding illegal access
by unauthorized users.
Perform the following configuration in system view.

Introduction to FTP Client
As an additional function provided by the Switch 7700, the FTP client is an
application module and has no configuration functions. The switch connects the
FTP clients and the remote server and inputs the command from the clients for
corresponding operations (such as creating or deleting a directory).
Trivial File Transfer Protocol (TFTP) is a simple protocol for file transmission that 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 originates with the client. To download a file, the client sends a
request to the TFTP server and receives the data, then sends an acknowledgement
to it. To upload a file, the client sends a request to the TFTP server and transmits
data to it, then receives the acknowledgement from it.
