Router maintenance when it serves as the client
When the router serves as the client, you can run FTP server program on your PC
as the FTP server, and set the server path. Then, add user name and password for
the router.
Configure the IP addresses of the two sides to be in the same network. In this
section, the FTP server is set to 192.168.0.1, and the Ethernet interface connected
to it (Ethernet interface 0/0 in this example; so, any interface is OK) is set to
192.168.0.2. Both can use the
ping
command to check if the connection is
successful.
Step 2: Maintain the router through the terminal connected to the console port as
follow:
<H3C>ftp 192.168.0.1
