Item Description
Authentication Key
Set the shared key for RADIUS authentication packets and that for RADIUS
accounting packets.
The RADIUS client and the RADIUS authentication/accounting server use MD5 to
encrypt RADIUS packets, and they verify the validity of packets through the
specified shared key. Only if the shared key of the client and that of the server are
the same, will the client and the server receive and respond to packets from each
other.
IMPORTANT:
•
The shared keys configured on the device must be consistent with those
configured on the RADIUS servers.
•
The shared keys configured in the common configuration part are used only
when no corresponding shared keys are configured in the RADIUS server
configuration part.

Quiet Time
Set the time the device keeps an unreachable RADIUS server in blocked state.
If you set the quiet time to 0, when the device needs to send an authentication or
accounting request but finds that the current server is unreachable, it does not
change the server's status that it maintains. It simply sends the request to the next
server in active state. As a result, when the device needs to send a request of the
same type for another user, it still tries to send the request to the server because the
server is in active state.
You can use this parameter to control whether the device changes the status of an
unreachable server. For example, if you determine that the primary server is
unreachable because the device's port for connecting the server is out of service
temporarily or the server is busy, you can set the time to 0 so that the device uses the
primary server as much.
Server Response Timeout
Time
Set the RADIUS server response timeout time.
If the device sends a RADIUS request to a RADIUS
server but receives no response within the specified
server response timeout time, it retransmits the
request. Setting a proper value according to the
network conditions helps in improving the system
performance.
IMPORTANT:
The server response timeout
time multiplied by the
maximum number of RADIUS
packet transmission attempts
must not exceed 75.
Request Transmission
Attempts
Set the maximum number of attempts for
transmitting a RADIUS packet to a single RADIUS
server. If the device does not receive a response to
its request from the RADIUS server within the
response timeout period, it retransmits the RADIUS
request. If the number of transmission attempts
exceeds the limit but the device still receives no
response from the RADIUS server, the device
considers the request a failure.
