Cisco Cisco NAC Appliance 4.8.3 Release Notes

As of Release 4.7(0), Cisco NAC Appliance no longer contains the “www.perfigo.com” Certificate 
Authority in the .ISO or upgrade image. Administrators requiring the “www.perfigo.com” CA in the 
network must manually import the CA from a local machine following installation or upgrade to Release 
4.8.

In order to establish the initial secure communication channel between a CAM and CAS, you must 
import the root certificate from each appliance into the other appliance’s trusted store so that the CAM 
can trust the CAS’s certificate and vice-versa.

Clean Access Manager 4.8(3) is bundled with version 4.8.3.9 of the Cisco NAC Agent and version 
4.8.3.594 of the Mac OS X Agent.

Cisco NAC Appliances assume the keyboard connected to be of US layout for both direct and IP-KVM 
connections. Use a US layout keyboard or ensure that you know the key mapping if you are connecting 
a keyboard of different layout.

To upgrade from Cisco NAC Appliance Release 4.1(8) or earlier to Release 4.8(3), you must first 
upgrade your system to Release 4.6(1), 4.7(x), or 4.8 and then upgrade to Release 4.8(3).
