Description
Use the dot1x authentication-method command to configure the
authentication method for 802.1x user.
Use the undo dot1x authentication-method command to restore the default
authentication method of 802.1x user.
By default, CHAP authentication is used for 802.1x user authentication.
Password Authentication Protocol (PAP) is a kind of authentication protocol with
two handshakes. It sends password in the form of simple text.
Challenge Handshake Authentication Protocol (CHAP) is a kind of authentication
protocol with three handshakes. It only transmits username but not password.
CHAP is more secure and reliable.
In the process of EAP authentication, switch directly sends authentication
information of 802.1x user to RADIUS server in the form of EAP packet. It is not
necessary to transfer the EAP packet to standard RADIUS packet first and then
send it to RADIUS server.
Please note: To realize PAP, CHAP or EAP authentication, RADIUS server should
support PAP, CHAP or EAP authentication respectively.
