Command-Line Interface
To troubleshoot an MX2010 router, you use the Junos OS CLI, alarms, devices connected to the alarm
relay contacts, and LEDs on both the components and craft interface.
LEDs—When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the
craft interface. In addition, you can also use the component-specific LEDs on the craft interface and on
the faceplate of a component to troubleshoot the routing matrix.
