Setting the maximum number of RADIUS request transmission attempts
About setting the maximum number of RADIUS request transmission attempts
RADIUS uses UDP packets to transfer data. Because UDP communication is not reliable, RADIUS uses a retransmission mechanism to improve reliability. A RADIUS request is retransmitted if the NAS does not receive a server response for the request within the response timeout timer. For more information about the RADIUS server response timeout timer, see "Setting the status of RADIUS servers."
You can set the maximum number for the NAS to retransmit a RADIUS request to the same server. When the maximum number is reached, the NAS tries to communicate with other RADIUS servers in active state. If no other servers are in active state at the time, the NAS considers the authentication or accounting attempt a failure.
