7.5 Updating an Application Using FTP
When the application file is large, you can also update it using FTP to save updating
and maintenance time.
As an application layer protocol in the TCP/IP suite, File Transfer Protocol (FTP) is
mainly used for file transfer between remote hosts. FTP provides reliable and
connection-oriented data transfer service over TCP. Compared with TFTP, the FTP
software is much bigger.
There are two approaches to updating an application file using FTP:
z
Through the BootWare menu. In this approach, the router can serve as the FTP
client only.
z
Through the CLI. In this approach, the router can serve as the FTP server or the
FTP client.
