The JUNOS software command-line interface (CLI) is the primary tool for controlling
and troubleshooting services gateway hardware, the JUNOS software, 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 the Routing Engine. The port labeled AUX attaches the Routing Engine to a laptop,
modem, or other auxiliary device, the port labeled CONSOLE attaches to a system
console, and the port labeled ETHERNET attaches to a management LAN. For more
information, see "Routing Engine Interface Ports and Status Indicators" on page 21.
