A RADIUS server usually checks whether a user is online by a timeout timer. If it receives from the 

NAS no real-time accounting packet for a user in the timeout period, it considers that there may be 

line or device failure and stops accounting for the user. This may happen when some unexpected 

failure occurs. In this case, the NAS is required to disconnect the user in accordance. This is done 

by the maximum number of accounting request transmission attempts. Once the limit is reached 

but the NAS still receives no response, the NAS disconnects the user. 

z 

Suppose that the RADIUS server response timeout period is 3 seconds (set with the timer 

response-timeout  command), the timeout retransmission attempts is 3 (set with the retry 

command), and the real-time accounting interval is 12 minutes (set with the timer 

realtime-accounting command), and the maximum number of accounting request transmission 

attempts is 5 (set with the retry realtime-accounting command). In such a case, the device 

generates an accounting request every 12 minutes, and retransmits the request when receiving no 

response within 3 seconds. The accounting is deemed unsuccessful if no response is received 

within 3 requests. Then the device sends a request every 12 minutes, and if for 5 times it still 

receives no response, the device will cut the user connection.
