RADIUS servers might not recognize usernames that contain the ISP domain names. In this case,
you can configure the device to remove the domain name of each username to be sent.
If two or more ISP domains use the same RADIUS scheme, configure the RADIUS scheme to keep
the ISP domain name in usernames for domain identification.
The device reports online user traffic statistics in accounting packets. The traffic measurement units
are configurable, but they must be the same as the traffic measurement units configured on the
RADIUS accounting servers.
To set the username format and the traffic statistics units for a RADIUS scheme:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter RADIUS scheme view.
radius scheme
radius-scheme-name
N/A
3.
Set the format for usernames
sent to the RADIUS servers.
user-name-format
{
keep-original
|
with-domain
|
without-domain
}
By default, the ISP domain name
is included in a username.
4.
(Optional.) Set the data flow
and packet measurement
units for traffic statistics.
data-flow-format
{
data
{
byte
|
giga-byte
|
kilo-byte
|
mega-byte
}
|
packet
{
giga-packet
|
kilo-packet
|
mega-packet
|
one-packet
} }*
By default, traffic is counted in
bytes and packets.
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 "
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.
To set the maximum number of RADIUS request transmission attempts:
Step Command
Remarks
1.
Enter system view.

2.
Enter RADIUS scheme view.

3.
Set the maximum number of
RADIUS request transmission
attempts.

The default setting is 3.
Setting the status of RADIUS servers
To control the RADIUS servers with which the device communicates when the current servers are no
longer available, set the status of RADIUS servers to blocked or active. You can specify one primary
RADIUS server and multiple secondary RADIUS servers. The secondary servers function as the
backup of the primary server. When the RADIUS server load sharing feature is disabled, the device
chooses servers based on the following rules:
•
When the primary server is in active state, the device communicates with the primary server.
•
If the primary server fails, the device performs the following operations:
{
Changes the server status to blocked.
