    With the "normal" ArubaOS switches we  can configure  "device fingerprinting "

    Can we do the same with CX ?

    There is no current support in CX for Device Fingerprinting.

    Wait I am not sure I understand the question can someone help me.  I have been doing device fingerprinting on CX prior to 10.8.  In fact Im pretty sure I been fingerprinting since CX-OS 10.6 at least maybe even earlier.

    Maybe you are asking something different for me I am device fingerprinting at CPPM and then passing a switch role to the switch.  Is the question asking something different?

    Fingerprinting on CPPM (and combined with MAC auth) is something different than this device fingerprinting.

    The fingerprinting discussed here is in the switch to bypass authentication for certain devices like APs. I personally think that is a pretty bad idea, as you lose all visibility, and it can be easily spoofed without leaving a trace in your access tracker. With ClearPass you could do it what probably any AOS-CX version. Fingerprinting in the switch has the benefit that you don't need ClearPass.

    If you have the choice, I would include ClearPass (but you may know that I'm somewhat biased on that topic).

    Hi Herman,
    Was talking about   still using  cppm, just using the devcie fingerprinting collector capabilities ( cdp, snmp, http, dhcp, lldp) of the switch ( as available in 2930 range) to update whats on clearpass ... still using  clearpass for role application

    Certainly wasn't planning on having  switches doing their own thing and  losing the vlity clearpass goves you

    Or do you mean the feature available on a 2930 where you can enable http,lldp,cdp and dhcp collectors on the switch and upload the fingerprints to clearpass?
    Can u do that in CX?

    This is the first phase released on AOS-CX.  The integration with other products will come in future releases.  In this phase, there will be limited Central 2.5.4 support, where the hostname can be sent from the client to central via device fingerprinting.

    In other words, the "plumbing" on the switch is there, future Central, ClearPass, and CPDI support will be coming.

    This DFP video can provide more details (starts at 11:46).

    Device fingerprinting is supported in ArubaOS-CX version 10.08.  Check out the most current Release Notes or the AOS-CX v10.08 Command-Line Interface Guide for more info.
