1-3Only users with the manage level can use the ftp command to log in to an FTP server, enter FTP clientview, and execute directory and file related commands. However, whether the commands can beexecuted successfully depends on the authorizations of the FTP server.Establishing an FTP ConnectionTo access an FTP server, an FTP client must establish a connection with the FTP server. Two ways areavailable to establish a connection: using the ftp command to establish the connection directly; usingthe open command in FTP client view.Source address binding means to configure an IP address on a stable interface such as a loopbackinterface, and then use this IP address as the source IP address of an FTP connection. The sourceaddress binding function simplifies the configuration of ACL rules and security policies. You just need tospecify the source or destination address argument in an ACL rule as this address to filter inbound andoutbound packets on the device, ignoring the difference between interface IP addresses as well as theaffect of interface statuses. You can configure the source address by configuring the source interface orsource IP address. The primary IP address configured on the source interface is the source address ofthe transmitted packets. The source address of the transmitted packets is selected following theserules:z If no source address is specified, the FTP client uses the IP address of the interface determined bythe matched route as the source IP address to communicate with an FTP server.z If the source address is specified with the ftp client source or ftp command, this source address isused to communicate with an FTP server.z If you use the ftp client source command and the ftp command to specify a source addressrespectively, the source address specified with the ftp command is used to communicate with anFTP server.The source address specified with the ftp client source command is valid for all FTP connections andthe source address specified with the ftp command is valid only for the current FTP connection.Follow these steps to establish an FTP connection (In IPv4 networking):To do… Use the command… RemarksEnter system view system-view —Configure the source addressof the FTP clientftp client source { interfaceinterface-type interface-number | ipsource-ip-address }OptionalA device uses the IPaddress of the interfacedetermined by thematched route as thesource IP address tocommunicate with the FTPserver by default.Exit to system view quit —
