Select Device Summary. This section identifies the total number of registered end-points and how many to each node. ○ Monitor during endpoint reset to ensure registration prior to the regeneration of the next certificate. ○ ○ Tip: The regeneration process of some certificates can impact endpoints. Consider an action plan after regular business hours due to the requirement to restart services and reboot phones. Verify phone registration via RTMT before, during, and after the process is highly recommended. You are only required to restart services if the services are running on the server. Warning: Endpoints that currently have an ITL mismatch (Bad ITL) can have registration issues after this process. For devices with a bad ITL, the deletion of the ITL on the endpoint is a typical best practice solution after the regeneration process is completed, and all other phones have registered. Please review specific phone models on how to delete ITL/CTL (Security) certificates. Identify Cluster Security Mode
