You can use two interfaces to monitor, configure, troubleshoot, and manage a J-EX Series
Switch: the J-Web graphical user interface and the Junos OS command-line interface
(CLI). Both of these user interfaces are shipped with the switch. This topic describes the
CLI. For information about the J-Web user interface, see "J-Web User Interface for J-EX
Series Switches Overview" on page 129.

CLI Overview
Junos OS CLI is a command shell that runs on top of a UNIX-based operating system
kernel. The CLI provides command help and command completion.
The CLI also provides a variety of UNIX utilities, such as Emacs-style keyboard sequences
that allow you to move around on a command line and scroll through recently executed
commands, regular expression matching to locate and replace values and identifiers in
a configuration, filter command output, or log file entries, store and archive router files
on a UNIX-based file system, and exit from the CLI environment and create a UNIX C
shell or Bourne shell to navigate the file system, manage switch processes, and so on.
CLI Help and Command Completion
To access CLI Help, type a question mark (?) at any level of the hierarchy. The system
displays a list of the available commands or statements and a short description of each.
