    Posted Apr 27, 2025 08:20 PM

    This short technote "Aruba New Central Device Insights and ClearPass Integration" as the name suggests covers the integrating ClearPass and Aruba New Central . With this integration Aruba Central sends the device profiling information and insights to ClearPass.  Device Insight (DI) is part of the Aruba Central Platform and uses data collectors (APs, CX switches and gateways) that are on your network to continuously gather metadata. You can then setup device tags based on location, application categories/types, device type/OS attributes used in ClearPass enforcement policies.

    Hope you'll find it useful and as always please send through your feedback for improvement.

    Issue with this solution, is that Clearpass information is overwritten.
    I have tried this earlier, but had to remove it, because that systems like raspberry pi where recognized in Central as linux computers, not raspberry pi. And therefore the rule in Central got corrupted, and the systems where sent to different network. As of many other systems as well.

    Had it only added the Device insight rule, it would have been a lot better, but when it screws up the database in central, then its useless. :(

    I had so much hope for this, and still have, but I cannot have central rewriting Clearpass with other categories/family that is more general than Clearpass' database.

    Anyone that have found an solution to this?

    with New Central, the device gets profiled a lot better. Like in this case of RPi, the vendor for it is "Raspberry Pi". See the screenshot below.

    Check out Evoko Naso booking plates.

    Clearpass has the ability to map those to Evoko Family.

    Central - Not so much.

    If I now enable this integration between Central and Clearpass, then classification will be overwritten as Unclassified or set to something quite different, like Generic or Smartdevice or something else.

    when you enable the ClearPass integration with Aruba Central,  you get the notice that all the new classification/discovery will be done by Device Insight that is in Aruba
    Central, so if you want to add other classification info , you need to add it via Aruba Central the way I created the tag in the technote.

    In the context of Customers migrating from AOS8 overtime how does this integration effect DHCP Fingerprinting of both AP's and Clients on AOS8 where DHCP Relay is used to relay the Fingerprint  info to ClearPass.  It is not clear if ClearPass then stops listening to these requests once this integration with Central is done?

    ClearPass will still listen, but forward the fingerprints to Central for profiling; then after profiling the result is shared back to ClearPass.

    Having said that, if the client connects via an AP, switch or gateway, managed by Central, Central will get the same data already; so it may be a bit redundant to keep ClearPass as ip-helper.

    As you know I have a post about this (https://airheads.hpe.com/discussion/new-hpe-networking-central-clearpass-tag-exchange#bm8f80ac0a-4c76-4100-a83e-5b5e63785444), but I get this 

    But if I select eu central 3 I cannot validate the certificate without getting an error!!

    Thanks for this!

    One remark though. You mention in your 2.1 Things You Need "ClearPass Policy Manager 6.11.x", and later in 3.2 ClearPass Integration to SSH to the CPPM and enter the "configure central-communication 1" command through SSH. This command has only been added to ClearPass since 6.11.10 (https://arubanetworking.hpe.com/techdocs/ClearPass/6.11/PolicyManager/Content/cmds/con-central-comm.htm). Don't ask me how I found out, please. :D

    Thanks Steven, I'll update the technote, BTW how did you find it :-)

    Can I use AOS-S switches as data collectors or does it have to be a CX switch? our environment is maybe 90% AOS-S and 10% CX

    New Central mainly performs the device profiling and behavior analysis,= which is then passed to ClearPass and there you can have policies based on device attributes. And sure AOS-S switches can be provide the basic info like client name, mac/IP address. If you has CX switch they could also get involved with Application DPI as well.
