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.

Table 266 Configure FTP Server Connection Timeout

Operation	Command
Configure FTP server connection timeouts	ftp timeout minute
Restoring the default FTP server connection	undo ftp	timeout
timeouts

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.

Table 267 Display and Debug the FTP Server

Operation	Command
Display FTP server	display	ftp-server
Display the connected FTP users.	display	ftp-user

The display ftp-servercommand 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-usercommand 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
