Command-Line Interface
The Junos OS command-line interface (CLI) is the primary tool for controlling and troubleshooting router
hardware, the Junos OS, routing protocols, and network connectivity. CLI commands display information
from routing tables, information specific to routing protocols, and information about network connectivity
derived from the ping and traceroute utilities.
You enter CLI commands on one or more external management devices connected to ports on the front
panel.
For information about using the CLI to troubleshoot the Junos OS, see the appropriate Junos OS
configuration guide.
Front Panel LEDs
The front panel on the router contains LEDs that allow you to troubleshoot the router.
