General Routing

  • On the QFX5130-32CD platform running Junos OS Evolved, you cannot clear or reset the disk option specified in the scheduled request node reboot command. The node reboots with the disk option last specified. PR1517596

  • On QFX5700, 400G DAC flap might be seen after OIR, FPC restart, device reboot enabling or disabling interface.PR1618488

  • On QFX5700, ungraceful removal (OIR) of FPC or an FPC fault might result in a PCIE MAJOR alarm PCI Uncorrected error on dev 0000:00:03.0 which does not get cleared. The only way to clear this alarm is reboot of the device. There are 2 situations in which this alarm can be seen:

    1. FPC is faulty: In rare FPC fault cases, the PCI Uncorrected error alarm might be seen along with FPC going to a Fault state as indicated by the show chassis fpc command. This is accompanied by other FPC major alarms. Once the faulty FPC is replaced with a good one, the alarm is still seen, and a reboot is required to clear this alarm. Post identification of the fault and FPC replacement, this alarm is harmless, and FPC state can be confirmed through the show chassis fpc command.

    2. Ungraceful OIR: The ungraceful removal of FPCs is not recommended on QFX5700. This operation might result in PCI Uncorrected Error alarm.

    Use one of the following two methods to do a graceful FPC OIR removal:

    • Execute the request chassis fpc slot <slot > offline command from the CLI.

    • Press the Offline Button for 1 second on the FPC to offline the FPC. Once the FPC is gracefully offlined both LEDs - PWR and STS go off. The FPC can be removed at this point.
