Reauth on AP wired port not working

    Posted Sep 20, 2022 11:07 AM
    I have an AP 503H that has a requirement to perform mac base auth  on devices conected to ethernet port E1 ( controller running

    In clearpass I'm  returning

    Aruba-User-Role: authenticated - i.e using the default mobility controller  "authenticated" role
    Session-Timeout = 3600
    Termination-Action = 1

    Tunnel-Medium-Type = 6
    Tunnel-Private -Group-Id = 333
    Tunel-Type = 13

    So everything works in that the  client is placed in vlan 333 and gets an ip adress via dhcp ... except ... i don't get  a reauth  time of 1 hour .. reauths seem to be fairly random.

    Normally use DUPs now so its been a while doing it this way, but fairly convinced that  it should work. The mobiliy controller is set to  accept reauths from cppm and recognise  Termination-Action

    The client in question is a baby NEOPI02  Ubuntu box

    Am i missing anything?

    BTW, notice that seems to have been pulled form asp.arubanetworks.com, certainly  cant see it being available  for download ... was there an issue with it ?

    does "show user Mac <mac-address>"  give you any detail about session timeout received from ClearPass?

    Please note that the reauth will only happen if the client sends any traffic. If the client is 'silent', it may take till the next packet that the client sends before the MAC reauth will happen.

    And have you enabled the reauthentication checkbox on the MAC Authentication profile? I can imagine that without set, there is no reauth.

    Did wonder if the client snoozing would affect things . Yes reauth enabled. A s also to recognise the termination - action ...... but will triple check
