Parameters
retry-times: Maximum number of accounting request transmission attempts. It ranges
from 1 to 255 and defaults to 5.
Description
Use the retry realtime-accounting command to set the maximum number of
accounting request transmission attempts.
Use the undo retry realtime-accounting command to restore the default.
Note that:
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.
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.
