FTP Configuration 335
FTP services are implemented in this way: An FTP client sends FTP requests to the FTP
server. The FTP server receives the requests, perform operations accordingly, and
return the results to the FTP client.
To prevent unauthorized accesses, an FTP server disconnects a FTP connection when it
does not receive requests from the FTP client for a specific period of time known as
the connection idle time.
To log into an FTP server, a user needs to provide a user name and a password for
being authenticated, and the FTP server authorizes the FTP client by providing the
information about work directory. FTP services are available to users only when they
pass the authentication and authorization.
Displaying and debugging an FTP server
After the above configurations, you can run the display command in any view to
view the running information of the FTP server and verify your configurations.
FTP Configuration: A
Switch Operating as an
FTP Client
The function for a switch to operate as an FTP client is implemented by an application
module built in the switch. A switch can operate as an FTP client without any
configuration. You can perform FTP-related operations (such as creating/removing a
directory) by executing FTP client commands on a switch operating as an FTP client.
Table 292 lists the operations that can be performed on an FTP client.
