Profile Manager and 802.1X
Profile Manager interoperates with RADIUS when it is working in the client mode. When a port is blocked due to 802.1X authentication failure, the LLDP packets cannot come in on that port. Therefore, the Aruba AP cannot be detected and the device profile cannot be applied. When the port gets authenticated, the LLDP packets comes in, the AP is detected, and the device profile is applied.
You must ensure that the RADIUS server will not supply additional configuration such as VLAN or CoS during the 802.1X authentication as they will conflict with the configuration applied by the Profile Manager. If the RADIUS server supplies any such configurations to a port, the device profile will not be applied on such ports.
