NAC Support Logs in 4.5

Many people might be wondering what happen to the handy dandy support logs that used to be located in the "/perfigo/logs/" directory in previous NAC versions. Well in version 4.5 there were some enhancements to the logging and with those enhancements came new placement of the logs.

These logs are most commonly used to troubleshoot NAC during deployments. Please do not turn on advanced logging without reading the documentation fully or with the assistance of Cisco TAC.

The CAM log can be found at:


The CAS log can be found at:


For those of you not familiar with what the logs contain, please feel free to reference the CAM and CAS Configuration Guides:

NAC Version Matrix

In June of 2006, NAC Version 4.0.0 was released. Since then, Cisco has released numerous updates and features to the NAC Appliance line! Recently a member of the NAC Mailing List posted the following request:

Is there a feature matrix to compare the various versions/tracks of
Cisco NAC?

So that is exactly what this posts answers. It is long, but I know at least one person appreciates it!

I will explore 3 major lines of code.. 4.0.X, 4.1.X and 4.5.X. Realistically all new deployments should be using 4.1.X or 4.5.X, but I wanted to give a good overview for everyone on older codes.
