To set up HPE Aruba Networking ClearPass Policy Manager (CPPM) for certificate-based

authentication of 802.1X supplicants, you need to upload the root CA certificate as a Trusted CA with

the EAP usage. This configuration allows the ClearPass server to validate the certificates presented

by the supplicants during the 802.1X authentication process. By marking the certificate for EAP

usage, ClearPass can properly authenticate the supplicant devices using the trusted certificate

authority (CA) that issued their certificates.

Reference: Configuration guidelines and best practices for ClearPass Policy Manager are available in

Aruba's ClearPass documentation, specifically detailing the steps for uploading and configuring root

CA certificates for EAP-based authentication.
