Setting the Response Timeout Timer of RADIUS Server
RADIUS (authentication/authorization or accounting) request packet is transmitted
for a period of time. If NAS has not received the response from RADIUS server, it
has to retransmit the request to guarantee RADIUS service for the user.
Perform the following configurations in RADIUS server group view.
Table 22 Set Response Timeout Timer of RADIUS Server
Operation
Set response timeout timer of
RADIUS server
Restore the response timeout
timer of RADIUS server to
default value
By default, timeout timer of RADIUS server is 3 seconds.
Setting Retransmission Times of the RADIUS Request Packet
Since RADIUS protocol uses UDP packet to carry the data, the communication
process is not reliable. If the RADIUS server has not responded NAS before
timeout, NAS has to retransmit RADIUS request packet. If it transmits the packet
for more than retry-time, and RADIUS server still has not given any response, NAS
considers the communication with the current RADIUS server has been
disconnected and will transmit the request packet to other RADIUS servers.
Perform the following configurations in RADIUS server group view.
Table 23 Set Retransmission Times of RADIUS Request Packet
Operation
Set retransmission times of
RADIUS request packet
Restore the default value of
retransmission times
By default, RADIUS request packet will be retransmitted up to three times.
Setting a Real-time Accounting Interval
To implement this feature, it is necessary to set a real-time accounting interval.
After the attribute is set, NAS will transmit the accounting information of online
users to the RADIUS server regularly.
