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 attempts, in the range 1 to 255.
Description
Use the retry realtime-accounting command to set the maximum number of accounting attempts.
Use the undo retry realtime-accounting command to restore the default.
By default, the maximum number of accounting attempts is 5.
A RADIUS server usually checks whether a user is online by a timeout timer. If it receives no real-time
accounting request for a user in the timeout period from the NAS, it considers that there may be line or
device failures and stops accounting for the user. This may happen when some unexpected failure occurs.
To cooperate with this feature of the RADIUS server, the NAS needs to disconnect the user in accordance.
The maximum number of accounting attempts, together with some other parameters, enables the NAS to
disconnect the user in time.
NOTE:
The maximum number of accounting attempts, together with some other parameters, controls how the
NAS sends accounting request packets.
Suppose that the RADIUS server response timeout period is three seconds (set with the timer
response-timeout command), the maximum number of RADIUS packet transmission attempts is three (set
with the retry command), the real-time accounting interval is 12 minutes (set with the timer
realtime-accounting command), and the maximum number of accounting attempts is five (set with the
retry realtime-accounting command). In this case, the device generates an accounting request every 12
minutes, and retransmits the request if it sends the request but receives no response within three seconds.
If the device receives no response after transmitting the request three times, it considers the accounting
attempt a failure, and makes another accounting attempt. If five consecutive accounting attempts fail, the
device cuts the user connection.
