Figure 1: Authentication Messaging Exchange Initiated by the Supplicant.

EAPOL-Logoff

Exchange of EAPOL frames

When the supplicant sends an EAPOL-Logoff message to the authenticator

the port under 802.1x control is set to unauthorised.

A successful authentication message exchange, initiated and ended by a

supplicant using OTP authentication, is shown in below.

To minimise the risk of denial-of-service attacks by issuing EAPOL-Logoff

messages to an Authenticator Port Access Entity (PAE) from a third party

device, we recommend that 802.1x not be used in a shared media LAN.
