No security policy server is

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

2. Enter RADIUS scheme view.

3. Interpret the class attribute as
CAR parameters.
attribute 25 car
By default, RADIUS attribute 25 is not
interpreted 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.
• The ratio of the number of failed transmission attempts to the total number of authentication request
transmission attempts reaches the threshold. This threshold ranges from 1% to 100% and defaults to
30%. This threshold can only be configured through the MIB.
The failure ratio is typically small. If a trap message is triggered because the failure ratio is higher than
the threshold, troubleshoot the configuration on and the communication between the NAS and the
RADIUS server.
