Using the Command-Line Interface to Troubleshoot the M40e Router
The JUNOS Software command-line interface (CLI) is the primary tool for controlling and troubleshooting router 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 through ports on the Connector Interface Panel (CIP). The port labeled AUXILIARY 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 M40e Connector Interface Panel (CIP) Description.
For information about using the CLI to display details about alarms generated by interfaces and hardware components, see Using Chassis and Interface Alarm Messages to Troubleshoot the M40e Router.
For information about using the CLI to troubleshoot the JUNOS Software, see the appropriate JUNOS Software configuration guide.
