40 CHAPTER 2: ABOUT THE COMMAND LINE INTERFACE
Command Modes
The Cuda 12000 switches and routes IP traffic between cable modems on an
analog HFC network, and an IP digital network. As a result, administration
tasks range from configuring IP interfaces and routing protocols to
managing subscribers.
To support these administration tasks, the system provides a set of global
commands and multiple command modes.
Global commands can be accessed anywhere in the CLI, while each
command mode provides access to a set of related commands that cover a
particular configuration scope. The current command mode is displayed in
the prompt by default; you can verify the current mode that you are in at
anytime by using the show mode command.
Command mode structure follows a hierarchy in which some modes run
within others; all run within root mode. You can back up to the parent level
from any sub mode using the up command. For local access, note that you
can exit the CLI command shell and return to the Linux prompt at any time
by typing quit. For Telnet or SSH access, the quit command terminates your
session (you can also type q, which is a shortened form of quit).
You can also display a list of all available commands within the current mode
by using one of the following help commands:
Help Command Description
help Displays the commands and command
descriptions.
?Displays all commands available within the
current mode without descriptions; you
can also display all commands by pressing
the Tab key twice.
