Using Keyboard Shortcuts and CLI
One useful shortcut built into the PremierWave 2050 module is that the complete text of a
command does not have to be entered to issue a command. Typing just enough characters to
uniquely identify a command, then hitting enter, can be used as a short cut for a command. For
example, at the enable level, "
sh
" can be used for the "
show
" command.
Tab Completion is also available using the
Tab
and
Enter
keys on the keyboard. Typing the first
few characters of a command, then hitting the
Tab
key displays the first command that begins with
those characters. Hitting the
Tab
key again displays the next command that begins with the
original characters typed. You can press
Enter
to execute the command or you can backspace to
edit any parameters.
The following key combinations are allowed when configuring the intelligent gateway using the
CLI:

Understanding the CLI Level Hierarchy
The CLI hierarchy is a series of levels. Arranging commands in a hierarchy of levels provides a
way to organize and group similar commands, provide different levels of security, and reduce the
complexity and number commands and options presented to a user at one time.
When you start a command line session, you begin at the login level. This level can be password
protected and provides access to high level status, a few diagnostic commands, and the enable
level. Further module information and configuration are accessed via the enable level.
The enable level can also be password protected and is the gateway to full configuration and
management of the intelligent gateway. There are commands for gathering and effecting all
elements of module status and configuration, as well as commands that take you to additional
levels. For instance, network specific status and configuration commands are found under the
"configuration" level.
