extensive

SIB F13/F2S slot-number

State of the TXP-F13 SIB or TXP-F2S SIB:

  • Activating—Transitional state when the SIB is transitioning to the Online or Spare state.

  • Deactivating—Transitional state when the SIB is going offline.

  • Online—SIB is operational and running.

  • Offline—SIB is powered down.

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

  • Empty—No SIB is present.

  • Fault— SIB is in alarmed state because of the following reasons and the cause of the error must be resolved:

    • On-board fabric ASIC is not operational.

    Note:

    If a SIB is not inserted properly, the SIB cannot transition to the Online or Spare state, and therefore cannot transition to the Check state.

extensive

SIB F13 slot-number  Odd/Even

State of the TXP-F13 SIB even and odd port connection optical links from the TX Matrix Plus router (SFC) to the router (LCC) in the routing matrix . The left four ports on the SFC are labeled Even and provide connections to one even-numbered LCC—LCC0 or LCC2. The right four ports on the SFC are labeled Odd and provide connections to one odd-numbered LCC—LCC1 or LCC3.

extensive

LCC number, SIB slot-number

State of the SIB on the LCC that is connected to the Even or Odd port on the TXP-F13 SIB faceplate:

  • Links ok—Links between the TXP-F13 SIB on the SFC and the LCC are active.

  • Links error—One or more links between the TXP-F13 SIB on the SFC and the LCC, have experienced an error, but the affected links remain operational.

  • Unused—No SIB is present.

extensive

State of the SG chip ports on the LCC:

  • Links ok—Link is active.

  • Link error—Link is operational with errors.

  • Link error crc saturated—CRC has exceeded the rate threshold and reached saturation without optical issues—that is, a cable has not been cut, removed, or otherwise experienced an error.

  • Link error crc saturated with optical errors—CRC has exceeded the rate threshold and reached saturation with optical issues—that is, a cable has been cut, removed, or otherwise experienced an error.

  • Unused—Port is not in use.

Fabric Management SIB State Output Fields for the show chassis fabric plane extensive Command on a TX Matrix Plus Router

SIB slot-number 

State of the SIBs on the T1600/T4000 router (LCC) in the routing matrix:

  • Activating—Transitional state when the SIB is coming online.

  • Deactivating—Transitional state when the SIB is going offline.

  • Connected—SIBS on an LCC are connected and trained, but are either not online or are spare, because the plane on the the TX Matrix Plus router (SFC) is still offline.

    The LCC SIB transitions to the Connected state when the F13 SIB to which it connects is online but the SFC plane (to which the LCC SIB connects) is offline for some reason; for instance, when there are insufficient number of F2 SIBs in the plane.

  • Disconnected—If an F13 SIB on the TX Matrix Plus router (SFC) goes offline, then the SIBs on the LCCs connected to the F13 SIB get disconnected.

    On the TX Matrix Plus router with 3D SIBs, the LCC SIB is also disconnected if the F13 SIB is online, but none of the cables are connected or trained.

    The Disconnected state is valid only for SIBs on an LCC. An LCC SIB transitions to the Disconnected state when the F13 SIB to which it connects goes Offline, irrespective of the state of the SFC plane.

    SFC Error—If an F13 SIB on the TX Matrix Plus router (SFC) transitions to the Fault state (because of link errors, for instance), and 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 applicable only to the SIBs on an LCC.

  • Online—SIB is operational and running.

  • Offline—SIB is powered down.

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

  • Empty—No SIB is present.

  • Fault— 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.

    • Link errors have exceeded the threshold

  • Check—SIB is in alarmed state where the SIB is partially operational because of link or destination errors. Only a SIB that is Online or Spare can transition to the Check state.

    Note:

    If a SIB is not inserted properly, the SIB cannot transition to the Online or Spare state, and therefore cannot transition to the Check state.

LCC SIB Link State
