Figure 22: 802.1x Authentication Scenario
The messages involved in the authentication procedure are illustrated in
The 7750 SR will initiate the procedure when the Ethernet port becomes operationally up, by
sending a special PDU called EAP-Request/ID to the client. The client can also initiate the
exchange by sending an EAPOL-start PDU, if it doesn't receive the EAP-Request/ID frame during
bootup. The client responds on the EAP-Request/ID with a EAP-Response/ID frame, containing
its identity (typically us password).
After receiving the EAP-Response/ID frame, the 7750 SR will encapsulate the identity
information into a RADIUS AccessRequest packet, and send it off to the configured RADIUS
server.
The RADIUS server checks the supplied credentials, and if approved will return an AccessAccept
message to the 7750 SR. The router notifies the client with an EAP-Success PDU and puts the port
in authorized state.
