Dot1X Dhcp-Launch - 3Com 5500-EI PWR Reference Manual

Parameters
chap: Authenticates using challenge handshake authentication protocol (CHAP).
pap: Authenticates using password authentication protocol (PAP).
eap: Authenticates using extensible authentication protocol (EAP).
Description
Use the dot1x authentication-method command to set the 802.1x authentication method.
Use the undo dot1x authentication-method command to revert to the default 802.1x authentication
method.
The default 802.1x authentication method is CHAP.
PAP applies a two-way handshaking procedure. In this method, passwords are transmitted in plain text.
CHAP applies a three-way handshaking procedure. In this method, user names are transmitted rather
than passwords. Therefore this method is safer.
In EAP authentication, a switch authenticates supplicant systems by encapsulating 802.1x
authentication information in EAP packets and sending the packets to the RADIUS server, instead of
converting the packets into RADIUS packets before forwarding to the RADIUS server. You can use EAP
authentication in one of the four sub-methods: PEAP, EAP-TLS, EAP-TTLS and EAP-MD5.
Related commands: display dot1x.
When the current device operates as the authentication server, EAP authentication is unavailable.
