Cisco strongly recommends running the latest 4.1.6.x version of the Clean Access Agent with release 4.1(6) of the CAM/CAS. 
If necessary, release 4.1(6) allows administrators to optionally configure the 4.1(6) CAM/CAS to allow 4.1.0.x Agent 
authentication and posture assessment (Windows only). Note that by default, 4.1.0.x Agents are not allowed to log into a 
4.1(6) Cisco NAC Appliance system. However, an Agent upgraded to 4.1.6.0 can still log into a 4.1(0) CAM/CAS. See 

 in the 4.1(1) release notes for details.
