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.
Follow these steps to enable the trap function for RADIUS:
To do...
Enter system view
Enable the trap function for
RADIUS
Enabling the RADIUS listening port of the RADIUS client
Only after you enable the RADIUS listening port of a RADIUS client, can the client receive and send
RADIUS packets. If RADIUS is not required, disable the RADIUS listening port to avoid attacks that exploit
RADIUS packets.
Follow these steps to enable the RADIUS listening port of a RADIUS client:
To do...
Enter system view
Enable the RADIUS listening port of
a RADIUS client
Displaying and maintaining RADIUS
To do...
Display the configuration information
of RADIUS schemes
Display the statistics for RADIUS
packets
Display information about buffered
stop-accounting requests for which no
responses have been received
Clear RADIUS statistics
Use the command...
system-view
radius trap { accounting-server-down |
authentication-error-threshold |
authentication-server-down }
Use the command...
system-view
radius client enable
Use the command...
display radius scheme
[ radius-scheme-name ] [ slot
slot-number ] [ | { begin | exclude |
include } regular-expression ]
display radius statistics [ slot
