6.2 Secure Device Communication
Ensure that RADIUS traffic is encrypted using shared secrets and that communication between ClearPass and network devices is secure.
Step 7: Monitoring and Troubleshooting
7.1 Use Dashboards
Utilize ClearPass monitoring tools to track authentication requests and resource access.
7.2 Troubleshoot Issues
Familiarize yourself with logging features to help troubleshoot authentication and policy issues.
