Usage guidelines
Typically, a RADIUS accounting server checks whether a user is online by using a timeout timer. If it does
not receive a real-time accounting request for a user in the timeout period from the NAS, it considers that
a line or device failure has occurred, and 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 RADIUS server response timeout period is 3 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 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
# Set the maximum number of accounting attempts to 10 for RADIUS scheme radius1.
<Sysname> system-view
[Sysname] radius scheme radius1
