Parameter
retry-times: The maximum number of real-time accounting request attempts that
have no responses. It is in the range 1 to 255.
Description
Use the retry realtime-accounting command to configure the maximum
number of real-time accounting request attempts allowed to have no responses.
Use the undo retry realtime-accounting command to restore the default.
RADIUS server usually checks whether a user is online using a 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. Accordingly, it is
necessary to disconnect the user at NAS end and on RADIUS server synchronously
when some unexpected failure occurs. 3Com Series Security Gateways support to
set maximum times of real-time accounting request failing to be responded. NAS
will disconnect the user if it has not received real-time accounting response from
RADIUS server for some specified times.
Suppose the response timeout timer of the RADIUS server is T and the real-time
accounting interval of NAS is t. Set T to 3, t to 12, and the maximum number of
real-time request retries to 5. With these values being configured, the NAS
generates an accounting request every 12 minutes, and retries if no response is
received within 3 minutes. If no response is received after five attempts, the NAS
assumes that this accounting fails. Normally, the result of retry-times multiple by T
is smaller than t.
The default realtime accounting retry times is 5.
