Parameter
retry-times: Specifies the maximum times of real-time accounting request
failing to be responded, ranging from 1 to 255. By default, the accounting request
can fail to be responded up to 5 times.
Description
Use the retry realtime-accounting command to configure the maximum
number of retries for real-time accounting requests. Use the
undo retry
realtime-accounting
command to restore the maximum number of retries for
real-time accounting requests to the default value.
RADIUS server usually checks if a user is online with timeout timer. If the RADIUS
server has not received the real-time accounting packet from NAS, it will consider
that there is line or device failure and stop accounting. Therefore, it is necessary to
disconnect the user at the NAS end and on the RADIUS server synchronously when
unexpected failure occurs. The Switch 4500 Series supports a maximum number
of times that real-time accounting requests can fail to be responded to. NAS will
disconnect the user if it has not received a real-time accounting response from the
RADIUS server for the number of specified times.
How is the value of count calculated? Suppose RADIUS server connection will
timeout in T and the real-time accounting interval of NAS is t, then the integer
part of the result from dividing T by t is the value of count. Therefore, when
applied, T is suggested the numbers which can be divided exactly by t.
