1. Checking for an access point (AP) in the Radius database
Before configuring the AP, you should verify that it is added to the NAS table of the Radius server. To do this, open the RADIUS/Access points management on RADIUS server menu. Find the access point by using the IP address filter.
2. RADIUS status checking
Select the RADIUS object in the object tree and go to the Monitoring/State checking menu.
Connect to the server console and start the command to verify that the process is running:
root@SoftWLC:/home/tester# ps -aux | grep eltex-radius
eltxrad 1609 0.0 0.9 358824 19728 ? Ssl 10:29 0:00 /usr/sbin/eltex-radius -f
root 6563 0.0 0.1 11688 2176 pts/0 S+ 12:49 0:00 grep --color=auto eltex-radius
3. SSID configuration
Open the SSID Manager in the Wireless/SSID manager menu.
Click Add SSID .
Set the following key settings:
Type - Enterprise
Name - Test_enterprise
Domain - root
Security mode - WPA Enterprise
RADIUS IP Address - 192.168.50.1 (ip address of Your Radius server).
RADIUS Key - eltex
RADIUS accounting - up
RADIUS accounting period - 600
Select the Radio interfaces to which the generated SSID will be assigned.
When you assign a SSID to all radio interfaces simultaneously ("Radio" - "All"), it is recommended to enable Band steer (select check box) for priority connection to the 5 GHz network by devices that support both bands.
When you assign a SSID on one radio interface, the Band steer mode should be off.
Примечание
VLAN-ID = 1000 is used as an example. It should be specified here the service VLAN that is actually used on Your network and comes to the access point. The DHCP server must be available to users in the VLAN.
After clicking the Accept button, the SSID created will be displayed in the SSID table.
Assign SSID to the access point. To do that, select created SSID and click Add SSID link button. In the appeared window, select the key for binding. Binding can be performed by MAC address or IP address of AP or by the host domain. Binding can be performed by MAC address of AP, by IP address of AP, or by the host domain. Then select the objects to bind (access points or nodes) and click Create binding, the indicator in the tree will change from yellow to green. Click Accept button.
A window will appear with the question “Do you want to fix SSID bindings?”. If you want to assign the created SSID to the points immediately, select “yes”. If it is necessary that the binding exists only in the database, but does not apply now to the access point - click “No”. Then, if necessary, you can go to the “SSID Bindings” tab and click the “Fix” button to assign SSID to the access point, or the binding will be corrected by triggering the corresponding monitor (default once a day).
You can control the SSID assignment process in the Tasks tab. 
The created binding appears in the SSID links tab .
The SSID will be assigned to the first disabled VAP on the access point. You can see the result in the Configuration/Virtual access points tab.
4. Creating Wi-Fi user accounts
The creation of accounts is performed in your Personal account.
To do this, go to the browser link:
http://192.168.50.1:8080/wifi-cab/
In the window that opens, enter the administrator credentials:
User name: admin
Password: password
Go to the Wi-Fi Users/Enterprise Users tab.
Click the Add button.
Set the login and password for the user, for example test/test. If necessary, the password can be generated by clicking the corresponding button at the end of the line 
.
If the SSID flag is set, authorization of this user will be possible only on the selected SSID.
If the Domain flag is set, authorization of the user will be possible on any SSID belonging to the selected domain.
If it is required, specify additional parameters: account validity time, tariff (previously created with specified restrictions), user name, mobile phone/Email, where new authorization data will be sent when changing them on schedule.
Click the Confirm button.
The user appears in the table.
Data about connected users will be displayed in EMS in the Wi-Fi Clients tab.
