Parameter 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.

Example # Set the maximum number of accounting request transmission attempts to 10 for
RADIUS scheme radius1.
