Parameters
retries: Specifies the maximum number of accounting attempts, in the range of 1 to 255.
Usage guidelines
Typically, a RADIUS accounting server checks whether a user is online by using a timeout timer. If
the server does not receive a real-time accounting request for a user in the timeout period, it
considers that a line or device failure has occurred. The server stops accounting for the user.
To work with the RADIUS server, the NAS needs to send real-time accounting requests to the server
before the timer on the server expires and to keep pace with the server in disconnecting the user
when a failure occurs. The NAS disconnects from a user according to the maximum number of
accounting attempts and specific parameters.
For example, the following conditions exist:
•
The RADIUS server response timeout period is 3 seconds (set by using the timer
response-timeout command).
•
The maximum number of RADIUS packet transmission attempts is 3 (set by using the retry
command).
•
The real-time accounting interval is 12 minutes (set by using the timer realtime-accounting
command).
•
The maximum number of accounting attempts is 5 (set by using the retry realtime-accounting
command).
In the above case, the device generates an accounting request every 12 minutes, and retransmits
the request if it sends the request but receives no response within 3 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.
Examples
# In RADIUS scheme radius1, set the maximum number of accounting attempts to 10.
<Sysname> system-view
[Sysname] radius scheme radius1
[Sysname-radius-radius1] retry realtime-accounting 10
