The network access device performs EAP termination and uses CHAP to communicate with the RADIUS
server.

2: System level
Parameters
chap: Sets the access device to perform Extensible Authentication Protocol (EAP) termination and use the
Challenge Handshake Authentication Protocol (CHAP) to communicate with the RADIUS server.
eap: Sets the access device to relay EAP packets, and supports any of the EAP authentication methods
to communicate with the RADIUS server.
pap: Sets the access device to perform EAP termination and use the Password Authentication Protocol
(PAP) to communicate with the RADIUS server.
Usage guidelines
The network access device terminates or relays EAP packets:
1. 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, and 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 clear text. The authentication method applies to
scenarios that do not require high security. To use PAP, the client must be an HP iNode 802.1X
client.
{ CHAP transports username in plaintext and encrypted password over the network. It is more
secure than PAP.
2. 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 configuration commands."
