To do… Use the command… Remarks
Specify to interpret the class
attribute as the CAR parameters
attribute 25 car
Required
Be default, RADIUS attribute 25 is not
interpreted as CAR parameters.
NOTE:
W
hether to configure this feature depends on the implementation of the device and the RADIUS server.
Enabling the RADIUS trap function
With the RADIUS trap function, a NAS sends a trap message in either of these situations:
• The status of a RADIUS server changes. If a NAS sends and retransmits an accounting or
authentication request to a RADIUS server but gets no response before the maximum number of
transmission attempts is reached, it considers the server unavailable and sends a trap message. If
the NAS receives a response from a RADIUS server in the blocked state, the NAS considers that the
RADIUS server is reachable again and also 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 you see a trap message triggered due to a higher failure ratio, check
the configurations on the NAS and the RADIUS server and the communications between them.
Follow these steps to enable the RADIUS trap function:
