3com 8807 Reference Guide

Use the reset stop-accounting-buffer command to reset the stopping 
accounting requests, which are saved in the buffer and have not been responded.

After transmitting the stopping accounting requests, if there is no response from 
the RADIUS scheme, the switch will save the packet in the buffer and retransmit it 
for several times, which is set through the retry stop-accounting command.

This command is used to delete the stopping accounting requests from the switch 
buffer. You can select to delete the packets transmitted to a specified RADIUS 
scheme, or according to the Session-id or username, or delete the packets 
transmitted during the specified time-range.

Related command: stop-accounting-buffer enable, retry stop-accounting, 
display stop-accounting-buffer.

retry retry-times

RADIUS scheme view

retry-times: Specifies the maximum times of retransmission, ranging from 1 to 20. 
By default, the value is 3.

Use the retry command to configure retransmission times of RADIUS request 
packet.

Use the undo retry command to restore the retransmission times to default value.

Because RADIUS protocol uses UDP packets to carry the data, its communication 
process is not reliable. If the RADIUS server has not responded NAS until timeout, 
NAS has to retransmit RADIUS request packet. Suppose the maximum 
retransmission times is N. If the accumulative transmission times is more than 
N-[N/2] but the primary RADIUS server still gives no answer, the NAS will consider 
that it has lost the communication with the current RADIUS server and then turn 
to transmit the request to another RADIUS server.
