Field Name

Field Description

Plane

(MX Series, MX2020 and MX2010 Routers only) Plane number.

State

(MX Series) State of the SIB or FPC:

  • Online—Switch Interface Board (SIB) is operational and running.

    Note: On the Enhanced MX SCB with Trio MPC, a maximum of 4 planes are operational and running. On all the other SCBs with Trio MPC, all the planes are operational and running.

  • Empty—SIB is powered down.
  • Check—SIB is in the Check state because of the following reasons:
    • SIB is not inserted properly.
    • Some destination errors are detected on the SIB. In this case, the Packet Forwarding Engine stops using the SIB to send traffic to the affected destination Packet Forwarding Engine.
    • Some link errors are detected on the channel between the SIB and a Packet Forwarding Engine. Link errors can be detected at initialization time or runtime:
      • Link errors caused by a link training failure at initialization time—The Packet Forwarding Engine does not use the SIB to send traffic. The show chassis fabric fpcs command shows Plane disabled as status for this link.
      • Link errors caused by CRC errors detected at runtime—The Packet Forwarding Engine continues to use the SIB to send traffic. The show chassis fabric fpcs command shows Link error as the status for this link.

    Note: The Check state does not apply to PTX Series Packet Transport Routers because there are no SIBs in the Check state.

    For information about link and destination errors, issue the show chassis fabric fpcs commands.

  • Spare—SIB is redundant and will move to active state if one of the working SIBs fails.

    Note: Spare does not apply to PTX Series Packet Transport Routers because there are no spare SIBs in the device.

(MX2010 and MX2020 Routers) State of the SFB.

  • Online—Switch Fabric Board (SFB) is operational and running.
  • Offline—Switch Fabric Board (SFB) is powered down.
  • Check—Switch Fabric Board (SFB) is in the check state.

Errors

(PTX Series only) Indicates whether there is any error on the SIB.

  • None—No errors
  • Link Errors—Fabric link errors were found on the SIB RX link.
  • Cell drops—Fabric cell drops were found on the SIB ASIC.
  • Link, Cell drops—Both Link errors and cell drops were detected on at least one of the FPC’s fabric links.

    Note: The Errors column is empty only when the FPC or SIB is offline.

Uptime

(MX Series, MX2010 and MX2020 Routers) Elapsed time the plane has been online.

 Note:
 For FPC slots with MPC Type 4 or MCC:
   Fabric planes 1 and 5, 3 and 7 use shared physical links.
   Those slots may run in a reduced bandwidth in case both
   plane 1 and 5, or both 3 and 7 are active.
