NOTE:
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
Before you can access the FTP server, you must first establish a connection from the FTP client to the FTP
server. You can either use the
ftp
command to establish the connection directly or use the
open
command
in FTP client view to establish the connection.
When using the
ftp
command, you can specify the source interface (such as a loopback ) or source IP
address. The primary IP address of the specified source interface or the specified source IP address is
used as the source IP address of sent FTP 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.

Configure the source address of
the FTP client

Optional
A switch uses the IP address
of the interface determined by
the matched route as the
source IP address to
communicate with the FTP
server by default.
