Configuring the IP address of the security policy server
The core of the HP EAD solution is integration and cooperation. The security policy server is the
management and control center for EAD. 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 the IP address of the IMC Platform on the NAS.
To configure the IP address of the security policy server for a scheme:
Step
1. Enter system view.
2. Enter RADIUS scheme
view.
3. Specify a security policy
server.
Configuring interpretation of the RADIUS class attribute as CAR parameters
This task is required when the RADIUS server supports assigning CAR parameters through the class
attribute and the device supports CAR parameters assignment.
According to RFC 2865, a RADIUS server assigns the RADIUS class attribute (attribute 25) to a RADIUS
client. However, the RFC only requires the RADIUS client to send the attribute to the accounting server on
an "as is" basis. It does not require the RADIUS client to interpret the attribute. When RADIUS servers use
the class attribute to deliver the assigned CAR parameters, the device must interpret the attribute as the
CAR parameters to implement user-based traffic monitoring and controlling.
To configure the device to interpret the RADIUS class attribute as CAR parameters:
Step
1. Enter system view.
2. Enter RADIUS scheme view.
3. Interpret the class attribute as
CAR parameters.
Enabling the trap function for RADIUS
With the trap function, the NAS sends a trap message when either of the following events occurs:
• The status of a RADIUS server changes. If the NAS receives no response to an accounting or
authentication request before the specified maximum number of RADIUS request transmission
attempts is exceeded, it considers the server unreachable, sets the status of the server to block and
sends a trap message. If the NAS receives a response from a RADIUS server that it considers
unreachable, the NAS considers that the RADIUS server is reachable again, sets the status of the
server to active, and sends a trap message.
