Configuring interpretation of RADIUS class attribute as CAR parameters

NOTE:

This task is required when the RADIUS server supports assigning CAR parameters through the class
attribute.

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, and it does not require the RADIUS client to interpret the attribute. Some RADIUS servers

use the class attribute to deliver the assigned committed access rate (CAR) parameters. In this case, the

access devices need to interpret the attribute to implement user-based traffic monitoring and controlling.

To support such applications, configure the access devices to interpret the class attribute as the CAR
parameters.
To configure an access device to interpret the RADIUS class attribute as CAR parameters:

Enabling the trap function for RADIUS

With the trap function, a NAS sends a trap message when either of the following events occurs:

The status of a RADIUS server changes. If a 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 generally 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.
