ONFIGURATION
The communication in RADIUS is unreliable because this protocol adopts UDP
packets to carry data. Therefore, it is necessary for the switch to retransmit a
RADIUS request if it gets no response from the RADIUS server after the response
timeout timer expires. If the maximum number of transmission attempts is reached
and the switch still receives no answer, the switch considers that the request fails.

Specify the type of

supported by the switch
For the primary and secondary servers (authentication/authorization servers, or
accounting servers) in a RADIUS scheme:
When the switch fails to communicate with the primary server due to some server
trouble, the switch will actively exchange packets with the secondary server.
After the time the primary server keeps in the block state exceeds the time set
with the timer quiet command, the switch will try to communicate with the
primary server again when it receives a RADIUS request. If the primary server
recovers, the switch immediately restores the communication with the primary
server instead of communicating with the secondary server, and at the same time
restores the status of the primary server to the active state while keeping the
status of the secondary server unchanged.
When both the primary and secondary servers are in active or block state, the
switch sends packets only to the primary server.
Description
-
Required
By default, a RADIUS scheme named
"system" has already been created in the
system.
Optional
By default, the system tries three times to
transmit a RADIUS request.
Command Description

radius-scheme-name
By default, a RADIUS scheme named
"system" has already been created in the
system.
server-type { extend Optional
ed | standard }
By default, the switch supports the
standard type of RADIUS server. The type
of RADIUS server in the default RADIUS
scheme "system" is extended.
