show chassis fabric plane

Number of the plane.

State of each plane:

• ACTIVE—SIB is operational and running.

• FAULTY— SIB is in alarmed state where the SIB’s plane is not operational for the following reasons:

  • On-board fabric ASIC is not operational.

  • Fiber-optic connector faults.

  • FPC connector faults.

  • SIB midplane connector faults.

Slot number of each Flexible PIC Concentrator (FPC).

Slot number of each Packet Forwarding Engine and the state of the links to the FPC:

• Links ok: Link between SIB and FPC is active.

• Link error: Link between SIB and FPC is not operational.

• Unused: No FPC is present.

State of the fabric plane:

• Online: Fabric plane is operational and running and links on the SIB are operational.

• Offline: Fabric plane state is Offline because the plane does not have four or more F2S and one F13 online.

• Empty: Fabric plane state is Empty if all SIBs in the plane are absent.

• Spare: Fabric plane is redundant and can be operational if the operational fabric plane encounters an error.

• Check: Fabric plane is in alarmed state due to the following reason and the cause of the error must be resolved:

  • One or more SIBs (belonging to the fabric plane) in the Online or Spare states has transitioned to the Check state.

    Check state of the SIB can be caused by link errors or destination errors.

• Fault: Fabric plane is in alarmed state if one or more SIBs belonging to the plane are in the Fault state. A SIB can be in the Fault state because of the following reasons:

  • On-board fabric ASIC is not operational.

  • Fiber-optic connector faults.

  • FPC connector faults.

  • SIB midplane connector faults.

  • Link errors have exceeded the threshold.
