Using Keyboard Shortcuts and CLI
One useful shortcut built into XPort Pro Lx6 embedded device server 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 device server 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 device 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 device server. There are commands for gathering and effecting all elements of 
device status and configuration, as well as commands that take you to additional levels. For 
instance, tunnel specific status and configuration is found under the "tunnel" level, and network 
specific status and configuration commands are found under the "configuration" level.
