1.1.1 Introduction to FTP

The File Transfer Protocol (FTP) is commonly used in IP-based networks to transmit
files. Before the World Wide Web comes into being, files are transferred through
command lines, and the most popular application is the FTP. At present, although
E-mail and Web are the usual methods for file transmission, the FTP still has its
strongholds.
As an application layer protocol, the FTP is used for file transfer between a remote
server and a local host. TCP port 21 is used for control connections, and port 20 is used
for data connections. Basic FTP operations are described in RFC959.
FTP-based file transmission is performed in the following two modes:
Binary mode, which is used for program file transfer.
ASCII mode, which is used for text file transfer.
An Ethernet switch can act as an FTP client or an FTP server in an FTP
implementation.
FTP server
An Ethernet switch can function as an FTP server to provide file transmission services
for FTP clients. You can log into a switch functioning as an FTP server by running an
FTP client program on your PC to access the files on the FTP server. To accept login
requests, an FTP server must be assigned an IP address.
