The command line interface of 3Com Router 3000 DSL has a number of
configuration commands, which can be used to configure and manage the
routers. The command line interface has the following characteristics:

Performing local or remote configuration through the Telnet command,
which can be used to directly log on and manage other routers.
Configuring the hierarchical user protection (includes guest, operator,
administrator). Only administrator users are authorized to configure and
manage the routers, so that unauthorized users would not be able to
invade the router illegally.
Users can enter <?> at any time to get online help.
Providing network diagnostic tools, such as Tracert and Ping, to quickly
diagnose the accessibility of the network.
Providing all kinds of detailed debugging information to diagnose network
faults.
The command line interpreter adopts fuzzy search for the keywords of the
command. Thus, you only need to enter the conflict-free keyword for the
interpretation of a command. For example, for the interpretation of a
display command, you can just input "dis".
The command line interface of 3Com Router 3000 DSL provides plenty of
configuration commands. Hierarchical user protection is adopted to prevent
unauthorized users from intruding.
In the system view, to facilitate the router management, all the commands are
grouped. Each group associates with a view. Users can use these commands to
switch between different configuration views. Normally, only certain commands
can be executed under a certain configuration mode, but some commands in
common use (such as ping, display current-configuration, and interface) can be
executed in all views.
