• The system supports 802.1X with EAP-MD5, EAP-OTP, EAP-TLS, EAP-TTLS, PEAPv0, PEAPv1, and MS-

CHAPv2 with PEAP.

• All platforms support only RADIUS as the authentication server.

• If the primary RADIUS server becomes unresponsive, the authenticator begins using a secondary

RADIUS server, if configured.

• 802.1X is not supported on port-channels or port-channel members.

• 802.1X is not supported on a port when you configure the port as cascaded.
