1-9z The specified interface must be an existing one. Otherwise a prompt appears to show that theconfiguration fails.z The value of the ip-address argument must be the IP address of the device where the configurationis performed. Otherwise a prompt appears to show that the configuration fails.z The source interface/source IP address set for one connection is prior to the fixed sourceinterface/source IP address set for each connection. That is, for a connection between an FTPclient and an FTP server, if you specify the source interface/source IP address used for theconnection this time, and the specified source interface/source IP address is different from thefixed one, the former will be used for the connection this time.z Only one fixed source interface or source IP address can be set for the FTP client at one time. Thatis, only one of the commands ftp source-interface and ftp source-ip can be valid at one time. Ifyou execute both of them, the new setting will overwrite the original one.Configuration Example: A Switch Operating as an FTP ServerNetwork requirementsA switch operates as an FTP server and a remote PC as an FTP client. The application switch.bin ofthe switch is stored on the PC. Upload the application to the remote switch through FTP and use theboot boot-loader command to specify switch.bin as the application for next startup. Reboot the switchto upgrade the switch application and download the configuration file config.cfg from the switch, thus toback up the configuration file.z Create a user account on the FTP server with the username switch and password hello.z The IP addresses 1.1.1.1 for a VLAN interface on the switch and 2.2.2.2 for the PC have beenconfigured. Ensure that a route exists between the switch and the PC.Network diagramFigure 1-4 Network diagram for FTP configurations: a switch operating as an FTP serverConfiguration procedure1) Configure Switch A (the FTP server)# Log in to the switch and enable the FTP server function on the switch. Configure the user name andpassword used to access FTP services, and specify the service type as FTP (You can log in to a switchthrough the Console port or by telnetting the switch. See the Login module for detailed information.)# Configure the FTP username as switch, the password as hello, and the service type as FTP.
