Command-Line Interface Overview
This chapter provides an overview of the JUNOS software command-line interface (CLI). For more detailed information about using the JUNOS software CLI, see the JUNOS System Basics Configuration Guide and the JUNOS Protocols, Class of Service, and System Basics Command Reference.
The CLI is the interface to the software that you use whenever you access the router—whether from the console or through a remote network connection. The CLI, which automatically starts after the router finishes booting, provides commands that you use to perform various tasks, including configuring the JUNOS software, and monitoring and troubleshooting the software, network connectivity, and the router hardware.
