Hello,
Currently working with a customer who is running ISE 2.4 patch 3 and experiencing issues with NMAP OS detected. The devices are being profiled as Apple iPhone devices correctly, but NMAP then reports the OS detected as running "Cisco Nexus 7010 switch (NX-OS 5) (accuracy 98%)".

operating-system Cisco Nexus 7010 switch (NX-OS 5) (accuracy 98%)
Obviously an Apple iPhone is not running a Nexus 7010 OS, any help or pointers would be greatly appreciated.
thanks..

Hi,
This is a known issue and we are working on a fix. Suggest trying to use another profiling probe instead of NMAP OS scan in the mean time.

Thanks Tim, appreciate your response.
Just to set expectations with the customer, do you know when we expect to have a fix?
Cheers,
Ian

Tim,
Is this really a bug? NMAP OS detection has been notoriously sketchy for a long time. I thought it was just a function of NMAP and not so much an ISE issue.

Hi,
I have a similar problem but in my case I have:
EndPointSource NMAP Probe
OUI Apple, Inc.
host-name iPhone
operating-system-result Windows 10 Enterprise
But I am not receiving information about "operating-system" parameter only "operating-system-result". Any idea why my iphone is not answering?
