Command-Line Interface
The Junos OS command-line interface (CLI) is the primary tool for controlling and
troubleshooting router hardware, 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 Routing Engine.
For information about using the CLI to troubleshoot Junos OS, see the appropriate Junos
OS configuration guide.
