Serviceability

  • Command to show alarm references (PTX10002-36QDD, PTX10008, and PTX10016)—You can see the platform-specific alarms on your router.

    Use the show system alarms reference operational-mode command to monitor system alarms and work with JTAC to resolve issues so that you can bring your system back to a healthy state.

    The output from the command includes:

    • Alarms that are not associated with any specific field-replaceable units (FRUs) (chassis-level alarms)

    • Alarms that are associated with a specific FRU

    • Remedies (if available) for each alarm listed

  • Sustained ingress Packet Forwarding Engine oversubscription log messages and alarms (PTX10001-36MR, PTX10002-36QDD, PTX10003, PTX10004, PTX10008, and PTX10016)—The system will periodically monitor WAN ingress drop statistics, MAC pause frames, and flow control frames (depending on the flow control mechanism used), to report sustained WAN ingress Packet Forwarding Engine oversubscription. The system logs a major Cmerror and raises a major alarm to indicate potential bursty traffic or unexpected packet drops. When the event is no longer present, the system clears the error and alarm and indicates this state in the INFO log. Use the show chassis alarms operational mode command to see the alarm.
