Set RADIUS accounting packet encryption key key accounting string
Restore the default RADIUS accounting packet
encryption key undo key accounting
By default, the encryption keys of RADIUS authentication/authorization and accounting
packets are all “3Com”.
40.3.4 Setting the Response Timeout Timer of a RADIUS Server After RADIUS (authentication/authorization or accounting) request packet has been
transmitted for a period of time, if NAS has not received the response from RADIUS
server, it has to retransmit the request to guarantee RADIUS service for the user.
You can use the following command to set response timeout timer of RADIUS server.
Perform the following configuration in RADIUS scheme view.
Table 40-13 Set the response timeout timer of a RADIUS server
Operation Command
Set response timeout timer of RADIUS server timer second
Restore the response timeout timer of RADIUS
server to default value undo timer
By default, timeout timer of a RADIUS server is 3 seconds.
40.3.5 Setting the Retransmission Times of RADIUS Request Packets Since RADIUS protocol uses UDP packet to carry the data, the communication process
is not reliable. If the RADIUS server has not responded NAS before timeout, NAS has
to retransmit RADIUS request packet. If it transmits more than the specified retry-times,
NAS considers the communication with the current RADIUS server has been
disconnected, and turn to send request packet to other RADIUS server.
You can use the following command to set retransmission times of RADIUS request
packet.
Perform the following configuration in RADIUS scheme view.
Table 40-14 Set the retransmission times of RADIUS request packets
Operation Command
Set retransmission times of RADIUS request
packet retry retry-times
Restore the default value of retransmission times undo retry
