  • 1.  APs flapping, heartbeat timeout

    MVP EXPERT
    Posted Apr 29, 2022 07:33 AM
    Hi,
    I have a test setup at home runnig Arubaos 8.10

    1 * MM VM
    1 * 7205 hardwar appliance
    2 * AP335s

    have a basic setup with  APs doing  eap-tls auth aganst cppm and that all works just fine.

    Problem is the APs are flapping with "AP is down since 2022-04-29 12:00:44 because of the following reason: Hbt Timeout."
    messages


    All devices are on the same vlan (1) nd same /24 net.
    All devices are pingable from other devices

    From the MM

    (nd7205) [MDC] *#show ap debug client-mgmt-counters

    Counters
    --------
    Name Value
    ---- -----
    Tunnel DACL 10
    STM Restart Notification to Auth 1
    Action frames: wmm rrm wnm public dls ba vendor unknown 0 0 0 0 0 0 0 0
    Associations Dropped Due to Auth Throttling 0
    PubSub Messages Rcvd 936
    Auth .1x Queue: High, Pending 550, 0
    Reg timer calls 8957
    BSS publish Failures 0
    Tunnel Timeouts 516

    Any ideas where i start looking to resolve the hbt-timeout issue ?

    How are the access points being powered?
    Are they negotiating the correct speed/duplex on the switch?

    I had a similar issue. It was due to a lack of AP licences. Probably worth to check that.

    I am having the same issue in version 8.10.0.0. Tried upgrading to 8.10.0.6 but nothing changed. TAC case is opened but the progress is slow. Is there any findings so far?
