R211x-HP Flexfabric 11900 Security Command Reference

99
• In EAP termination mode—The access device re-encapsulates and sends the authentication data
from the client in standard RADIUS packets to the RADIUS server. It performs either CHAP or PAP
authentication with the RADIUS server. In this mode the RADIUS server supports only
MD5-Challenge EAP authentication, and "username+password" EAP authentication initiated by an
iNode client.
{ PAP transports usernames and passwords in plain text. The authentication method applies to
scenarios that do not require high security. To use PAP, the client can be an HP iNode 802.1X
client.
{ CHAP transports username in plaintext and encrypted password over the network. It is more
secure than PAP.
• In EAP relay mode—The access device relays EAP messages between the client and the RADIUS
server. The EAP relay mode supports multiple EAP authentication methods, such as MD5-Challenge,
EAP-TL, and PEAP. To use this mode, you must make sure the RADIUS server supports the
EAP-Message and Message-Authenticator attributes, and uses the same EAP authentication method
as the client. If this mode is used, the user-name-format command configured in RADIUS scheme
view does not take effect. For more information about the user-name-format command, see
"RADIUS commands."
If RADIUS authentication is used, you must configure the network access device to use the same
authentication method (PAP, CHAP, or EAP) as the RADIUS server.
