Description
Specify the type of the RADIUS server supported by the switch,
including:
•
Extended—Specifies an extended RADIUS server (offered by
IMC). The RADIUS client and RADIUS server communicate using
the proprietary RADIUS protocol and packet format.
•
Standard—Specifies a standard RADIUS server. The RADIUS
client and RADIUS server communicate using the standard
RADIUS protocol and packet format defined in RFC 2138/2139 or
later.
Specify and confirm the shared key for the authentication server.
These two parameters must have the same values.
Specify and confirm the shared key for the accounting server. These
two parameters must have the same values.
Specify the source IP address for the switch to use in RADIUS packets
to be sent to the RADIUS server. It is recommended to use a loopback
interface address instead of a physical interface address as the
source IP address, because if the physical interface is down, the
response packets from the server cannot reach the switch.
Set the RADIUS server response timeout.
Set the maximum number of transmission attempts.
The product of the timeout value and the number of retransmission
attempts cannot exceed 75.
Set the real-time accounting interval, whose value must be n times 3
(n is an integer).
To implement real-time accounting on users, it is necessary to set the
real-time accounting interval. After this parameter is specified, the
switch will send the accounting information of online users to the
RADIUS server every the specified interval.
The value of the real-time accounting interval is related to the
requirement on the performance of the NAS and RADIUS server. The
smaller the value, the higher the requirement. It is recommended to
set a large value if the number of users is equal to or larger than
1000. Table 121 shows the relationship between the interval value
and the number of users.
Set the maximum number of real-time accounting request
retransmission times.
Enable or disable buffering stop-accounting requests without
responses in the switch.
Set the maximum number of transmission attempts if no response is
received for the stop-accounting packet.
Specify the interval the RADIUS servers have to wait before being
active
