[Sysname-radius-radius1] retry 5
retry realtime-accounting
Syntax
retry realtime-accounting retry-times
undo retry realtime-accounting
View
RADIUS scheme view
Default Level
2: System level
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:
z
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.
