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
and traceroute utilities.
You enter CLI commands on one or more external management devices connected to
ports on the Routing Engine.
For information about using the CLI to troubleshoot the Junos OS, see the appropriate
Junos OS configuration guide.
