    Try and run this command when you see the high CPU Usage

    show airgroup internal-state statistics verbose

    Near the bottom will tell you how much airgroup is using for CPU usage.  if it's high, you may be able to limit it by limiting which services are enabled for aigroup

    But as Herman said, if this is a production setup/you have TAC access, opening a case with them will get you the quickest/best resolution.

    We follow the suggestion of support team.We change the Airgroup from distribution mode to centralize mode,the cpu cost was down to 10%.
    Thanks for your help.We will try the other suggestions.

    For questions about high CPU/high memory/runaway processes/memory leaks, please try to upgrade to a recent version first. If the issue is still there, open a case with Aruba Support.

    These are situations that are not common, so it's unlikely that you will see a specific answer on this forum to a quite broad question like this one.
