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. 
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: 
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. 
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. 
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):
