What devices etc you using to implement NAC? Are you using ACS Server? or NAC Appliance?

What mode of NAC are you using? L2 dot1x; L2 IP or L3 IP?

What authentication are you using? (Take a look at your settings under System Config -> Global Authentication, if using Cisco ACS)

A lot of issues I have seen with NAC is down to certificates/ca chains on the NAC posture server and the end clients.

Hi Stu,

Thanks a lot for the response. We are using CAM and CAS appliance to implement NAC.

Mode of operation is L2 IP

We are using NAC only for Guest wireless. Users can authenticate fine but my problem is that it doesnt check to see if antivirus, windows updates etc is enabled or not.

Please let me know if you need more information.
