Alternative Actions

Check for FPC alarms on the router craft interface. You can physically look at the craft interface or use the show chassis craft-interface command. When a red or yellow alarm occurs, the craft interface goes into alarm mode. Alarm mode preempts idle mode, displaying a message to alert you of serious alarm conditions. In alarm mode, the screen displays the following information:

+--------------------+

|myrouter            |

|1 Alarm active      |

|R: Slot 2:errors    |

|                    |

+--------------------+

The craft interface output provides the following information:

• First line—Name of the router.
• Second line—Number of alarms active on the router.
• Third and fourth lines—Individual alarms, with the most severe condition shown first. Each line indicates whether the alarm is a red (R) or yellow (Y) alarm.
