Configuring the FTP Client
Only users with the manage level can use the ftp command to log in to an FTP server, enter FTP client
view, and execute directory and file related commands. However, whether the commands can be
executed successfully depends on the authorizations of the FTP server.
Establishing an FTP Connection
To access an FTP server, an FTP client must establish a connection with the FTP server. Two ways are
available to establish a connection: using the ftp command to establish the connection directly; using
the open command in FTP client view.
Before using the ftp command to establish a FTP connection, you can perform source address binding.
The source address binding means to configure an IP address on a stable interface such as a
loopback interface, and then use this IP address as the source IP address of an FTP connection. The
source address binding function simplifies the configuration of ACL rules and security policies. You just
need to specify the source or destination address argument in an ACL rule as this address to filter
inbound and outbound packets on the device, ignoring the difference between interface IP addresses
as well as the affect of interface statuses. You can configure the source address by configuring the
source interface or source IP address. The primary IP address configured on the source interface is
the source address of the transmitted packets. The source address of the transmitted packets is
selected following these rules:
z If no source address is specified, the FTP client uses the IP address of the interface determined
by the 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
is used to communicate with an FTP server.
z If you use the ftp client source command and the ftp command to specify a source address
respectively, the source address specified with the ftp command is used to communicate with an
FTP server.
The source address specified with the ftp client source command is valid for all FTP connections and
the 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):
