Configure a Radius AAA client | Cisco Systems 4.2 guide

Chapter 6 Agentless Host Support Configuration Scenario

Summary of Configuration Steps

GAME group feedback provides an added security check for MAC address authentication by checking the device type categorization that ACS determines by associating a MAC address with a user group against information stored in a database on an audit server.

To use the GAME group feedback feature, you must add a NAC attribute-value pair to the ACS RADIUS dictionary before configuring a posture validation policy that uses GAME group feedback.

You then configure a posture validation policy in a NAP that requests device type authentication from the audit server. For details on configuring posture validation, see Enable Posture Validation, page 7-46.

The detailed steps for configuring GAME group feedback are described in Enable GAME Group Feedback, page 7-46in Chapter 9, “NAC Configuration Scenario.”

Summary of Configuration Steps
