z When you back up an application, if the file name already exists on the AP, the system does not
output any information, but directly overwrites the existing file.
z For information about the tftp command, see FTP and TFTP in the Fundamentals Command
Reference in the H3C WA Series WLAN Access Points Command References.
z To back up a configuration file, use the same method.
Table 7-5 Output description of commands for application upgrade and backup when the AP serves as
a TFTP client

Upgrading the Applications Through FTP at the CLI
When the application file is large, you can also upgrade it using FTP to save upgrade and maintenance
time.
As an application layer protocol in the TCP/IP suite, the File Transfer Protocol (FTP) is mainly used for
file transfer between remote hosts. FTP provides reliable, connection-oriented data transfer service
over TCP. Compared with TFTP, the FTP software is much bigger.
The AP can only serve as the FTP client, rather the FTP server to provide FTP services.
Upgrading an Application Using FTP at the CLI
Setting Up an Upgrade Environment
