Description
Use the 
stop-accounting-buffer enable
 command to configure to save the 
stopping accounting requests without response in the Switch buffer. Use the 
undo 
stop-accounting-buffer enable
 command to cancel the function of saving the 
stopping accounting requests without response in the Switch buffer. 
By default, enable to save the stopping accounting requests in the buffer.
Because the stopping accounting request concerns the account balance and will 
affect the amount of charge, which is very important for both the user and ISP, 
NAS shall make its best effort to send the message to the RADIUS accounting 
server. Accordingly, if the message from the Switch to the RADIUS accounting 
server has not been responded to, the Switch shall save it in the local buffer and 
retransmit it until the server responds or discard the messages after transmitting 
for a specified number of times.

Example
To indicate that, for the server “3Com” in the RADIUS scheme, the Switch will 
save the stopping accounting request packets in the buffer, enter the following:

Parameter
seconds:
 RADIUS server response timeout timer, ranging from 1 to 10 and 
measured in seconds. By default, the value is 3.
Description
Use the 
timer
 command to configure RADIUS server response timer. Use the 
undo 
timer
 command to restore the default value of the timer. 
After a RADIUS (authentication/authorization or accounting) request packet has 
been transmitted for a period of time, if NAS has not received the response from 
the RADIUS server, it has to retransmit the message to guarantee RADIUS service 
for the user. The period taken is called RADIUS server response timeout time, 
which is controlled by the RADIUS server response timeout timer in the Switch. 
This command is used to set this timer. 
Setting a suitable timer according to the network situation will enhance system 
performance.
