Monitoring the Craft Interface

You monitor and maintain the craft interface or Front Panel Module (FPM) to ensure that you can view the router status and perform management operations from the panel on the front of the chassis. (See Table 51.) You can also display craft interface information from the JUNOS software command-line interface (CLI).
