FTP Server Configuration
Example
Networking Requirement
The Switch serves as FTP server and the remote PC as FTP client. The configuration
on FTP server: Configure a FTP user named as Switch, with password hello and
with read and write authority over the flash root directory on the PC. The IP
address of a VLAN interface on the Switch is 1.1.1.1, and that of the PC is 2.2.2.2.
The Switch and PC are reachable.
The Switch application
switch.app
is stored on the PC. Using FTP, the PC can
upload the
switch.app
from the remote FTP server and download the
config.cfg
from the FTP server for backup purpose.
