FTP (file transfer protocol) is commonly used in IP-based networks to transmit files. Before World Wide 

Web comes into being, files are transferred through command lines, and the most popular application is 

FTP. At present, although E-mail and Web are the usual methods for file transmission, FTP still has its 

strongholds. 

As an application layer protocol, FTP is used for file transfer between remote server and local client. 

FTP uses TCP ports 20 and 21 for data transfer and control command transfer respectively. Basic FTP 

operations are described in RFC 959. 

FTP-based file transmission is performed in the following two modes: 

z 

Binary mode for program file transfer 

z 

ASCII mode for text file transfer 

The device can act as an FTP client or the FTP server in FTP-employed data transmission: 

Table 1-1 Roles that the device acts as in FTP 

FTP server 

The device can operate as an FTP server to provide file 
transmission services for FTP clients. You can log in to the 
device operating as an FTP server by running an FTP client 
program on your PC to access files on the FTP server.  

FTP client 

In this case, you need to establish a connection between your 
PC and the device through a terminal emulation program or 
Telnet, execute the ftp X.X.X.X command on your PC. 
(X.X.X.X is the IP address of an FTP server or a host name), 
and enter your user name and password in turn. The device 
can operate as an FTP client, through which you can access 
files on the FTP server. 

The prerequisite 
is that a route 
exists between 
the device and 
the PC.
