HP 3600 v2 Series Configuration Manual page 46

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.
To enable the trap function for RADIUS:
Step
1. Enter system view.
2. Enable the trap
function for RADIUS.
Enabling the RADIUS client service
To receive and send RADIUS packets, enable the RADIUS client service on the device. If RADIUS is not
required, disable the RADIUS client service to avoid attacks that exploit RADIUS packets.
To enable the RADIUS client service:
Step
1. Enter system view.
2. Enable the RADIUS client
service.
Setting the DSCP value for RADIUS packets
Step
1. Enter system view.
2. Set the DSCP value for IPv4
RADIUS packets.
3. Set the DSCP value for IPv6
RADIUS packets.
