FTP Overview
FTP is a common way to transmit files on the Internet and IP network. Before the
World Wide Web (WWW), files were transmitted in the command line mode and FTP
was the most popular application. Even now, FTP is still used widely, while most users
transmit files using e-mail and Web.
FTP, a TCP/IP protocol on the application layer, is used for transmitting files between a
remote server and a local host.
The Switch provides the following FTP services:
■
FTP server: You can run FTP client program to log in the server and access the files
on it.
■
FTP client: After connected to the server through running the terminal emulator or
Telnet on a PC, you can access the files on it, using FTP command.
