It rangesfrom 1 to 255 and defaults to 5.DescriptionUse the retry realtime-accounting command to set the maximum number ofaccounting request transmission attempts.Use the undo retry realtime-accounting command to restore the default.Note that:z A RADIUS server usually checks whether a user is online by a timeout timer. If itreceives from the NAS no real-time accounting packet for a user in the timeoutperiod, it considers that there may be line or device failure and stops accountingfor 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 themaximum number of accounting request transmission attempts. Once the limit isreached 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 withthe timer response-timeout command), the timeout retransmission attempts is3 (set with the retry command), and the real-time accounting interval is 12minutes (set with the timer realtime-accounting command), and the maximumnumber of accounting request transmission attempts is 5 (set with the retryrealtime-accounting command). In such a case, the device generates anaccounting request every 12 minutes, and retransmits the request when receivingno response within 3 seconds. The accounting is deemed unsuccessful if noresponse is received within 3 requests. Then the device sends a request every 12minutes, and if for 5 times it still receives no response, the device will cut the userconnection.Related commands: radius scheme, timer realtime-accounting.Examples# Set the maximum number of accounting request transmission attempts to 10 forRADIUS scheme radius1.
