High cpu usage 6000 cx switch

  • 1.  High cpu usage 6000 cx switch

    Posted Oct 12, 2022 07:59 AM
    Hey everybody.

    I installed a new 6000 cx switch 52 port at a customer.
    I installed a sfp transceiver J4859D (which is unsupported) in one of the sfp ports.
    The switch is uplinked via fibre and the sfp.
    The switch is also acting as a core switch for other switches in the same building.

    Everything is working excellent.

    The issue is that I enabled all kinds of warnings and alarms in Aruba Central, and I get high CPU warning many times a day.
    I can not figure out what is causing the high cpu warning.

    Anybody have experience with high cpu on switches and figuring out what is causing that?

    check the release notes for firmware version 10.10.1010, perhaps it'll address it.
    You can also try these command on the switch to see what is causing it

    • top cpu
    • show system
    • show system resource-utilization

    with CX switches, please ensure you are running the latest maintenance release.
    for 10.10.x it is 10.10.1030
    the release notes mentions that the high CPU spike is resolved.

    Yes, I already tried this version.
    I have now updated to the latest version 10.11.0001
    And the problem continues.

    Release notes say:  Workaround: The spike is generally short-lived and can be ignored.

    Hello,

    I had similar problem earlier with 6100 and 10.12 combination but after 10.13.1000 I haven't suffered such problems any more.

    (If I recall right I think I got high CPU problems only with switches manufactured in 2020-2021)
