Configuring the IP address of the security policy server

The core of the H3C EAD solution is integration and cooperation, and the security policy server is the

management and control center. Using a collection of software, the security policy server provides
functions such as user management, security policy management, security status assessment, security

cooperation control, and security event audit.
The NAS checks the validity of received control packets and accepts only control packets from known

servers. To use a security policy server that is independent of the AAA servers, you must configure the IP
address of the security policy server on the NAS. To implement all EAD functions, configure both the IP

address of the security policy server and that of the IMC Platform on the NAS.
To configure the IP address of the security policy server for a scheme:

Specify a security policy

No security policy server is
specified by default.

NOTE:

You can specify up to eight security policy servers for a RADIUS scheme.

Enabling the RADIUS offload feature

Some RADIUS servers do not support Extensible Authentication Protocol (EAP) authentication. They

cannot process EAP packets. In this case, the access device must process EAP packets from EAP clients

before forwarding them to the server. The RADIUS offload feature enables an access device to process
EAP packets for this purpose.
The RADIUS offload feature needs the cooperation of the local EAP authentication server. They work

together as follows:

1.

After receiving EAP packets from an EAP client, the local EAP authentication server interacts with
the client, encapsulates the authentication information of the client into the RADIUS MS-CHAPv2
attribute and sends the attribute in a RADIUS authentication request to the RADIUS server for

authentication.

2.

When a RADIUS server receives the requests, it resolves the authentication information in the
request, performs authentication, and then encapsulates and sends the authentication result in a

RADIUS packet to the local EAP authentication server.

To deploy the RADIUS offload feature, complete the following tasks on the access device:

Configure the local EAP authentication server, specifying the EAP authentication method as
PEAP-MSCHAPv2 (the only authentication method supported). For more information about the

configuration, see "

Configuring local EAP authentication

."

Configure the EAP offload feature for the RADIUS schemes.
