I applied the Radius user experience monitor to my radius servers and I get the attached error message. What do I need to do to configure this monitor?
Based on the screenshot it appears to be a configuration issue. Most likely on the RADIUS server. You'll need to ensure that the Orion server itself is added as a valid RADIUS client configured to use PAP authentication. The shared secret must also be configured properly within the RADIUS User Experience Monitor to match the RADIUS client configuration on the RADIUS server.
