TitleWindows 10 End Systems Show Up in NAC With Missing OS Family and OS Type
Symptoms
In NAC Manager the OS Family and OS Type columns are blank for some Windows 10 systems
OS Detect does not work in Control Panel End systems
Environment
  • All NAC platforms
  • All Wireless platforms
  • All Wired platforms
  • Windows 10
  • IdentiFi Wireless
  • BYOD
  • OS DETECT
Cause
This caused by a new Windows 10 OS fingerprint that is unknown to versions of NAC prior to 7.0.
Resolution
  1. Upgrade to NAC version 7.0 or higher.  Version 7.0 will be released sometime in the Spring of 2016.
  2. Apply a DHCP Fingerprint Override with the applicable Windows 10 fingerprint (See additional notes).
Additional notes
A workaround if an upgrade is not currently an option is to apply a DHCP Fingerprint Override via NAC Manager >> Tools, Management and Configuration >> Advanced Configuration >> Global and Appliance Settings >> Appliance Settings >> Default. Click on the Device Type Detection tab then click Edit, under "DHCP Fingerprint Definition Overrides".  

Paste in the below XML code:

<DHCP created="2016-02-03" last_updated="2016-02-03" author="support@extremenetworks.com">
<fingerprints>
    <fingerprint os="Windows 8/ 8.1/ 10/ 2012" os_class="Windows" os_url="http://www.microsoft.com/windows" comments="" author="support@enterasys.com" lastmodified="2016-02-03">
        <tests>
            <test weight="5" matchtype="exact" dhcptype="Any" dhcpoption55="1,3,6,15,31,33,43,44,46,47,121,249,252"/>
        </tests>
    </fingerprint>
</fingerprints>
</DHCP>



Click OK.
Click Save (lower right corner of the screen) then perform an Enforce to the NAC appliance.
Re-test by release / renew of the End System's IP.


*Note that this applies to NAC versions 6.2 or higher as there was no Windows 10 support prior to this.

* Option 119 may need to be added prior to 8.1.4 for some recently upgraded Windows 10 OS as of 8/2018
