You have run an Active Endpoint Security Report on HPE Aruba Networking ClearPass.

When the Active Endpoint Security Report on HPE Aruba Networking ClearPass indicates that endpoints have MAC addresses but no known IP addresses, one effective step to address this issue is to add CPPM ' s (ClearPass Policy Manager) IP address to the IP helper list on routing switches. This configuration ensures that DHCP requests are forwarded to the ClearPass server, allowing it to track and report the IP addresses assigned to the endpoints. This helps ClearPass maintain an accurate mapping of MAC addresses to IP addresses, improving endpoint visibility and security management.
