Configure FTP	FTP (File Transfer Protocol), which belongs to the application layer protocol in the
	TCP/IP protocol suite, mainly provides file transfer between remote hosts. Borne
	on TCP, FTP provides reliable and connection-oriented data transfer service but
	does not provide access authorization and authentication mechanism.
	When the client originates control connection to a server (with port command)
	and establishes control connection with the server port numbered 21 via an
	arbitrarily allocated local protocol port number, this connection will be reserved
	until data transfer is complete. The server establishes data connection with the
	client via port 20 and transfer data.
	The 3Com Router 1.x provides FTP service, that is, the router serves as the FTP
	server. Users can run the FTP client application and logon to the router to access
	files on the router.
	Before using FTP, users need to install the FTP Client application. You need to
	purchase the FTP Client application as this is not supplied as part of the 3Com
	Router series.

■Configure authentication and authorization of the FTP server

■Start FTP server

Configure authentication and authorization of FTP server

1Set the authentication mode of the FTP server

The authorization information of the FTP server is the top-level working directory of FTP users. Only authenticated and authorized users can enjoy the service of the FTP server. The 3Com Router 1.x configures authentication and authorization of the FTP user using AAA. If no AAA is configured, the local user authentication is adopted by default.

When using AAA, the router cannot perform local accounting. Therefore, when using local authentication, you need to open the accounting option switch to disable the accounting function.

Please configure with the following commands in system view.
