RADIUS Protocol Configuration Commands 387 RADIUS server has been disconnected and it will transmit request packet to other RADIUS servers. Setting a suitable retry-time according to the network situation can speed up the system response. Related command: radius scheme Example To set to retransmit the RADIUS request packet no more than 5 times via the server 3Com in the RADIUS scheme, enter the following: system-view System View: return to User View with Ctrl+Z. [SW5500]radius scheme 3Com [SW5500-radius-3Com]retry 5 retry Syntax realtime-accounting retry realtime-accounting retry-times undo retry realtime-accounting View RADIUS Scheme View Parameter retry-times: Specifies the maximum times of real-time accounting request failing to be responded, ranging from 1 to 255. By default, the accounting request can fail to be responded up to 5 times. Description Use the retry realtime-accounting command to configure the maximum number of retries for real-time accounting requests. Use the undo retry realtime-accounting command to restore the maximum number of retries for real-time accounting requests to the default value. RADIUS server usually checks if a user is online with timeout timer. If the RADIUS server has not received the real-time accounting packet from NAS, it will consider that there is line or device failure and stop accounting. Therefore, it is necessary to disconnect the user at the NAS end and on the RADIUS server synchronously when unexpected failure occurs. The Switch 5500G-EI Family supports a maximum number of times that real-time accounting requests can fail to be responded to. NAS will disconnect the user if it has not received a real-time accounting response from the RADIUS server for the number of specified times. How is the value of count calculated? Suppose RADIUS server connection will timeout in T and the real-time accounting interval of NAS is t, then the integer part of the result from dividing T by t is the value of count. Therefore, when applied, T is suggested the numbers which can be divided exactly by t. Related command: radius scheme.
