Maintain the Routing Engine

To maintain the Routing Engine, perform the following procedures on a regular basis:

• Check the LCD and the Routing Engine LEDs on the craft interface. The LCD reports Routing Engine status during normal operation and describes the cause of failures when they occur. The green LED labeled OK lights steadily when the Routing Engine is functioning normally. For more information about the LEDs and LCD, see Craft Interface.
• Issue the CLI show chassis routing-engine command to check the status of the Routing Engine:

user@host> show chassis routing-engine
