248 CHAPTER 11: SYSTEM MANAGEMENT
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.
By default, the FTP server connection timeout is 30 minutes.
Displaying and Debugging the FTP Server
Execute the display command in all views to display the FTP Server configuration,
and to verify the effect of the configuration.
The display ftp-server command can be used for displaying configuration
information about the current FTP server, including, the maximum amount of users
supported by FTP server and the FTP connection timeout. The
display ftp-user
command can be used for displaying the detail information about connected FTP
users.
Introduction to FTP Client
As an additional function provided by the Switch 7750, 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).
TFTP 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.
TFTP configuration tasks include:
■ Configuring the File Transmission Mode
■ Downloading Files with TFTP
