ClearPass Configuration Problem

  • 1.  ClearPass Configuration Problem

    Posted Oct 07, 2021 09:22 AM

    I´ve implemented a Wired-MAC based Service for my switch ports. The service checks the category of the device, which is connected to the switch (Computer,VoIP Phone,Access Point).

    This works fine, the AccessPoint is recognized correctly and the appropiate VLANs are assigned (one untagged VLAN for the AP and two tagged VLANs).
    If I now try to establish a Wifi connection the correct service is hit and the correct profile is assigned. But I looks like, if the VLANs isn´t assigned correctly (The client didn´t get an IP address, so I guess it´s not in the correct VLAN).

    If I connect the AccessPoint to a port where I assign the VLANs (one unttagged, two tagged) static, everything is working fine. Not sure if it is a CPPM configuration or a switch configuration problem...

    Switch: Aruba 2530, (YA.16.10.0013)
    Access Point: Aruba IAP 305 (

    Can you please share your IAP configuration and ClearPass profile you are sending ?

    This is the profile for the AccessPoint:

    This is the profile for the Client:

    I think your client enforcement profile isn't correct.

    Try to use the vendor specific attribute "Aruba-User-Vlan".

    Sorry for the delay...
    I´ve changed the VSA to "Aruba-User-Vlan" but still the same problems. I don´t think the VSA is a problem, cause otherwise I would expect the client connection to fail all the time. But it works fine, when the IAP is connected to the port where the VLANs are assigend manually.

    Check the Access Tracker. You will see denied authentictions from your wireless devices against the wired mac auth services.

    Add Radius:Hewlett Packard HPE-Port-Macauth-Port-Mode = Port Mode and Radius:Hewlett Packard HPE-Port-Dot1x-Client-Limit = 0 to your AP Enforcement Profile.

    These rules will stop any new authentications on the switchport after the AP is authorized, basically trusting the attached device to handle the additional authentications. These are needed for any brand AP that bridges traffic.
