Suppose the maximum number of retransmission attempts is set to N. If the primary
RADIUS server does not respond after the number of request attempts exceeds (N –
[N/2]), the NAS considers that the current RADIUS server is disconnected and turns to
another RADIUS server.
Appropriately set the retry-times parameter to maintain an acceptable system response
speed.
Related command: radius scheme.
Example
# With the RADIUS scheme "huawei", a RADIUS request can be sent up to five times.
[3Com-radius-huawei] retry 5
1.2.20 retry realtime-accounting
Syntax
retry realtime-accounting retry-times
undo retry realtime-accounting
View

Parameter
retry-times: The maximum number of real-time accounting request attempts that have
no responses. It is in the range 1 to 255 and defaults to 5.
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. Huawei-3Com 3Com Series Routers 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
