Parameter
retry-times: Specifies the maximum times of retransmission, ranging from 1 to
20. By default, the value is 3.
Description
■ Use the retry command to configure the RADIUS request retransmission
times.
■ Use the undo retry command to restore the retry-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. If it transmits more than the
specified retry-time, NAS considers the communication with the current RADIUS
server has been disconnected and it will transmit request packet to other RADIUS
servers.
Setting a suitable retry-time according to the network situation can speed up the
system response.

Example
Set to retransmit the RADIUS request packet no more than 5 times via the server
3Com in the RADIUS server group.

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 times
of real-time accounting request failing to be responded.
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. Accordingly, it is necessary
to disconnect the user at NAS end and on RADIUS server synchronously when
some unexpected failure occurs. 3Com SW7700 Series Ethernet Switches support
to set maximum times of real-time accounting request failing to be responded.
