IMPORTANT:
Changing the RADIUS server type will restore the unit for data flows and that for the packets sent to the
RADIUS server to the defaults.
The supported RADIUS server type determines the type of the RADIUS protocol that the switch uses to
communicate with the RADIUS server. It can be standard or extended:
Standard—Uses the standard RADIUS protocol, compliant to RFC 2865 and RFC 2866 or later.
•
Extended—Uses the proprietary RADIUS protocol of HP.
•
When the RADIUS server runs on IMC, you must set the RADIUS server type to extended. When the
RADIUS server is implemented by third-party RADIUS server software, either RADIUS server type applies.
For the switch to function as a RADIUS server to authenticate login users, you must set the RADIUS server
type to standard.
To set the RADIUS server type:
Step
1. Enter system view.
2. Enter RADIUS scheme view.
3. Set the RADIUS server type.
Setting the maximum number of RADIUS request transmission attempts
Because RADIUS uses UDP packets to transfer data, the communication process is not reliable. RADIUS
uses a retransmission mechanism to improve the reliability. If a NAS sends a RADIUS request to a
RADIUS server but receives no response after the response timeout timer (defined by the timer
response-timeout command) expires, it retransmits the request. If the number of transmission attempts
exceeds the specified limit but it still receives no response, it tries to communicate with other RADIUS
servers in active state. If no other servers are in active state at the time, it considers the authentication or
accounting attempt a failure. For more information about RADIUS server states, see
RADIUS servers."
The maximum number of transmission attempts of RADIUS packets multiplied by the RADIUS server
response timeout period cannot be greater than 75 seconds. For more information about the RADIUS
server response timeout period, see
