To differentiate security levels based on device type (e.g., giving a VoIP phone different access than a laptop), ClearPass must use Profiling. The service first identifies the device type using various collectors and then evaluates this information in the Enforcement Policy. This allows the administrator to select specific Enforcement Profiles (VLANs/ACLs) that are dynamically assigned based on the high-fidelity profile data gathered at connection time.

While RADIUS requests (for network access) are almost always found in the Access Tracker, TACACS+ requests (for device administration) that fail early in the process---such as those from an unauthorized source IP---may not appear there. In these cases, the Event Viewer is the correct diagnostic tool. The Event Viewer captures system-level errors, including 'Unknown NAD' alerts for TACACS+ attempts, which will help the administrator identify why the request isn't being processed by a service.

This follows the standard two-stage authentication flow. The first 802.1X attempt fails posture (Unknown) and results in a quarantine redirect. The user runs the dissolvable agent, which sends health data to a WEBAUTH service. ClearPass saves this status. During the second authentication attempt, the 802.1X service checks the cached posture token associated with that device. Finding it is now 'Healthy,' ClearPass applies the full-access enforcement policy.

ClearPass Guest registration pages use dynamic AJAX/JavaScript polling to monitor the status of the account. When a sponsor clicks 'Approve,' the account state changes from 'disabled' to 'enabled' in the database. The receipt page detects this change in real-time, and the Log In button, which was previously grayed out or inactive, automatically becomes active, allowing the guest to connect without needing to refresh the page.

A common cause of certificate errors is a 'broken trust chain'. When uploading a new server certificate, the engineer must include the entire certificate bundle. This bundle should contain the server's certificate, any Intermediate CAs, and the Root CA certificate. This allows the ClearPass server to present the full chain to client browsers, ensuring they can verify the certificate's authenticity back to a trusted source.
