Troubleshooting

You recently configured a switch for 802.1X authentication using HPE Aruba Networking ClearPass. A security administrator observes events in ClearPass Event Viewer with this description:

RADIUS authentication attempt from unknown NAD (10.10.1.10:1812)

Which command should be used to identify the configuration issue?

Explanation

ClearPass recognizes a RADIUS NAD by the source IP address of the RADIUS request. The RADIUS-specific source-interface configuration determines that address; if it is 10.10.1.10 and ClearPass has no matching NAD definition, ClearPass reports an unknown NAD. show ip source-interface radius displays the configured source interface/IP for RADIUS traffic.
