z  If no primary IP address is configured on the specified source interface, no FTP connection can be 
established. 
z  If you use the ftp client source command to first configure the source interface and then the 
source IP address of the transmitted packets, the newly configured source IP address will take 
effect instead of the current source interface, and vice versa. 
 
Follow these steps to establish an FTP connection (In IPv6 networking): 
To do…  Use the command…  Remarks 
Log in to the remote FTP 
server directly in user view 
ftp ipv6 [ server-address 
[ service-port ] [ source ipv6 
source-ipv6-address ] [ -i 
interface-type interface-number ] ] 
ftp ipv6 
Log in to the remote FTP 
server indirectly in FTP client 
view 
open ipv6 server-address 
[ service-port ] [ -i interface-type 
interface-number ] 
Use either approach. 
The ftp ipv6 command 
is available in user view; 
and the open ipv6 
command is available in 
FTP client view.
