6.5 Upgrading an Application Using FTP
When the application file is large, you can also upgrade it using FTP to save upgrade
and maintenance time.
File Transfer Protocol (FTP) is an application layer protocol in the TCP/IP suite. It 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 upgrading an application file using FTP:
z
Using the BootWare menu. In this approach, the firewall can serve as the FTP
client only.
z
Using command lines. In this approach, the firewall can serve as the FTP server or
the FTP client.
