EAPoL (EAP) uses RADIUS protocol for EAP-authorized logons. RADIUS supports IPv4 and IPv6 addresses, with no difference in functionality or configuration.
Before configuring your device, you must configure at least one EAP RADIUS server and shared secret fields.
You cannot configure EAP on ports that are currently configured for:
Shared segments
MultiLink Trunking (MLT)
Change the status of each port that you want to be controlled to auto. The auto setting automatically authenticates the port according to the results of the RADIUS server. The default authentication setting for each port is authorized.
