Maintaining the Router
with FTP Server
Maintaining the router when it serves as the server
FTP (File Transfer Protocol) is an application layer protocol in the TCP/IP suite. It
mainly transfers files among remote hosts. Carried over TCP, it provides reliable
and connection-oriented data transfer service but does not provide access
authorization and authentication mechanism.
The FTP service provided by the router is FTP Server, that is to say, the router serves
as the FTP Server. You can run FTP Client to log onto the router and access files on
the router.
Install FTP Client before using FTP. No FTP Server is available with the H3C MSR 50
series. You must install one yourself. Take the FTP Client with Windows XP for
example.
Step 1: Build hardware maintenance environment as follows:

section, the PC server is set to 192.168.0.1, and the router Ethernet interface
connected to it (Ethernet interface 0/0 in this example; so, any interface is OK) is
