CLI User Interface Overview
You can use two interfaces to monitor, configure, troubleshoot, and manage a Juniper
Networks EX Series Ethernet Switch: the J-Web graphical user interface and the Junos
operating system (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 EX Series Switches Overview” on page 145.

CLI Overview
Junos operating system (Junos OS) CLI is a Juniper Networks specific 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.
