Table 1: show chassis sibs Output Fields

Field Name

Field Description

Slot

SIB slot number.

Type

(TX Matrix Plus router only) SIB type.

Uptime

How long the SIB has been up and running.

State

SIB status:

  • Activating—SIB is coming online; this is a transitional state.
  • Deactivating—SIB is going offline; this is a transitional state.
  • Connected—SIBs on a T1600 router are connected and trained but are either not online or are spare, because the plane on the TX Matrix Plus router (or switch-fabric chassis) is still offline.
  • Disconnected—SIBs on all T640 routers on the TX Matrix router (or switch-card chassis) are in the Disconnected state, because a SIB on the SCC has gone offline. Likewise, SIBs on all T1600 routers on the TX Matrix Plus router (or switch-fabric chassis) are in the Disconnected state, because a SIB on the SFC has gone offline.
  • Online—SIB is operational and running.
  • Offline—SIB is powered down.

    Note: If a SIB transitions to the Offline state, the command displays an appropriate reason in the output. For instance, if the SIB is taken offline using the request chassis sib command, the show chassis sibs command displays --- Offlined by cli command --- in the output.

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

    Note: Spare does not apply to PTX Series Packet Transport Switches, as there are no spare SIBs.

  • Empty—No SIB is present.
  • Fault—SIB is in an alarmed state in which the SIB’s plane is not operational for one of the following reasons:
    • Onboard fabric ASIC is not operational.
    • Fiber-optic connector faults.
    • FPC connector faults.
    • SIB midplane connector faults.
  • Check—SIB is in an alarmed state due to link errors or destination errors. A SIB can transition to the Check state from the online or spare state.

    The Check state can be caused by the following reasons:

    • Unsupported FPC installed on a router.
    • SIB not inserted properly (such as bent pins).
    • 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. When a Packet Forwarding Engine cannot be reached on that plane or SIB, a destination error is reported against that SIB.

      Note: For SIBs in the Check state, the output displays some additional information:

      • In Junos OS Release 9.6 and later, the Check state message shows the number of Packet Forwarding Engines in the plane having destination errors. For example, Check (10 destination errors) indicates 10 Packet Fowarding Engines cannot be reached on that particular SIB. If there are no destination errors, and if the SIB transitions to the Check state because of link errors only, the Check state message shows Check (0 destination errors).
      • In Junos OS Release 9.5 and earlier, the Check state message shows Check (destination errors) if there are Packet Forwarding Engines with destination errors in this plane. However, it does not show the number of Packet Forwarding Engines having destination errors. If there are no destination errors and if the SIB transitions to the Check state because of link errors only, the Check state message shows Check (no destination errors).

      If the SIB is in a Check state, because of destination errors, the CLI displays an additional line in the output, use "show chassis fabric fpcs" and "show chassis fabric sibs" for more details.

    • 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 Switches.

  • SFC Error—If an F13 SIB on the TX Matrix Plus router (SFC) transitions to the Fault state (for instance, because of link errors), and then if an LCC SIB (connected to the F13 SIB) comes online, the LCC SIB transitions to the SFC Error state. This state indicates that the F13 SIB to which the LCC SIB is connected has errors.

    Note: The Connected, Disconnected, and SFC Error states are only applicable to the SIBs on an LCC.

  • Invalid—The specific SIB slot is not valid for 4-LCC chassis configuration. See the TX Matrix Plus Hardware Guide for more information about the supported SIB slots.

    Note: The Invalid state is applicable to TX Matrix Plus routers only.

Fabric links

Indicates status of fabric links on the SIB.

  • Active—All Fabric links on SIB are active. Errors detected on the SIB’s Fabric links, if any, are reported in the Errors column.
  • Unused—All Fabric links on the SIB are not used for fabric traffic.

Errors

Indicates if there is any error on the SIB.

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