Troubleshooting: Offline SIBs on TX Matrix Plus Router

 

On a TX Matrix Plus router, none of the 3D SIBs are online. The problem might have occurred because of any of the following reasons:

Incorrect Software Version Installed on the TX Matrix Plus Router

Problem:

Description: On a TX Matrix Plus router, none of the 3D SIBs are online.

Cause

The software version installed on the TX Matrix Plus router (or the switch-fabric chassis (SFC)) is earlier than Junos OS Release 13.1

Solution

Check whether the software version installed on the SFC is earlier than Junos OS Release 13.1:

  1. Execute the show version command.

    user@host> show version
  2. If the software version is incorrect, then you must install the correct version of Junos OS. For information about downloading the correct version of the software, see Downloading Software.

Incorrect Front Panel Switch Setting

Problem:

Description: On a TX Matrix Plus router, none of the 3D SIBs are online.

Cause

The front panel switch of the TX Matrix Plus router (or the SFC) is configured incorrectly and the SFC was not rebooted after the configuration of the front panel switch.

Solution

  1. Check the configuration of the SFC front panel switch by executing the show chassis craft-interface command.

    user@host show chassis craft-interface
  2. If the switch setting is incorrect, then refer to Setting the Configuration Size and Switch-Fabric Chassis Number to correct the switch settings.

  3. Reboot the SFC after configuring the front panel switch.

  4. Execute the show chassis hardware command to check whether the TXP-F13-3D SIB and the TXP-F2-3D SIB are seen in the output of the command.

    user@host> show chassis hardware

SIB Hardware Failure

Problem:

Description: On a TX Matrix Plus router, none of the 3D SIBs are online.

Cause

A 3D SIB hardware failure can cause the 3D SIBs on a TX Matrix Plus router to go offline.

Solution

An error LED glows to indicate that a SIB is offline because of a hardware fault.

  1. To view the state of the SIB, execute the show chassis sibs command.

    user@host> show chassis sibs
  2. To rectify any hardware fault, remove and reinsert the SIB and then execute the request chassis sib online lcc number slot slot-number command to bring the SIB online.

  3. If the problem persists even after reinserting the SIB, then isolate the SIB and contact JTAC. For more information, refer to TX Matrix Plus Router Hardware Guide

Unsupported Hardware or Hardware Fault Alarms

Problem:

Description: On a TX Matrix Plus router, none of the 3D SIBs are online.

Cause

The 3D SIBs on a TX Matrix Plus router can go offline if there are any unsupported hardware or a hardware fault.

Solution

Check whether the output lists any unsupported hardware or hardware fault alarms.

  1. To view alarms, execute the show chassis alarms command.

    user@host> show chassis alarms
  2. To solve the errors listed in the output, refer to TX Matrix Plus Alarm Messages Overview.
