Configuring the RADIUS for Enterprise equipment and systems:


I can not post my config for my ASA appliance due to security concerns; but I can offer a little advise to the people out there about how the Radius operates for a Cisco Appliance

Assuming you have a Windows Server 2008 Box ....

Preparations:
Add Network Policy Server (NPS) to your server using roles
Add Host Credential Authorization Protocol (HCAP)

Step 1.) Open Network Policy
Step 2.) Go to the RADUIS Clients and right-click then select new
            Give your Appliance / Client/ Router and ID
            Add the IP or the Hostname, then tick the Generate radio button and now click Generate

Step 3.) Go to the manufacturer's website to complete the remainder of the specs needed to comply for the RADIUS configurations.
