Syntax
retry realtime-accounting retry-times
undo retry realtime-accounting
View
RADIUS scheme view
Parameters
retry-times: Maximum number of real-time accounting request attempts, ranging from 1
to 255.
Description
Use the retry realtime-accounting command to set the maximum number of real-time
accounting request attempts.
Use the undo retry realtime-accounting command to restore the default maximum
number of real-time accounting request attempts.
By default, the system can allow five real-time accounting request attempts at most.
Note that:
z Generally, the RADIUS server uses the connection timeout timer to determine
whether a user is online or not. If the RADIUS server receives no real-time
accounting packet for a specified period of time, it will consider that the line or the
switch is faulty and stop the accounting of the user. To make the switch cooperate
with this feature on the RADIUS server, it is necessary to cut down the user
connection on the switch as soon as possible after the RADIUS server terminates
the charging and connection of the user in the case of an unforeseen fault. For this
purpose, you can limit the number of continuous real-time no-response accounting
requests, and the switch will cut down the user connection if it sends out the
maximum number of real-time accounting requests but does not receive any
response.
z A real-time account request may be sent multiple times (set by the retry command
in RADIUS scheme view) for an accounting attempt. If no response is received
even after the number of transmission attempts reaches the maximum, the
accounting attempt fails. Suppose that the response timeout time of the RADIUS
server is three seconds (set by the timer response-timeout command), that the
maximum number of transmission attempts (set by the retry command) is 3, and
that the real-time accounting interval is 12 minutes (set by the timer
realtime-accounting command), the maximum number of real-time accounting
request attempts is 5 (set by the retry realtime-accounting command). In this
case, the switch sends an accounting request every 12 minutes; if the switch does
