Enabling RADIUS
Every unit has to be configured for RADIUS Communication to obtain authentication from the RADIUS Server.
Administrators should log on to the unit as any non-RADIUS user, and then configure the unit following these steps
to obtain authentication:
1. Click on the
RADIUS Tab.
Figure 62 RADIUS Configuration Display
2. Check the Enable RADIUS check box.
3. In the Primary Server IP field enter the address of the RADIUS server.
4. In the Shared Secret field, enter the password for the client, which was added while configuring the RADIUS
server. Please refer to Appendix D: RADIUS Server for additional information.
5. In the Port field, enter the port number – by default, the port number is 1812 , and should be modified in case
the RADIUS server is configured for a different port number. The early deployment of RADIUS was done
using the chosen port number
1645 , which conflicts with the “Datametrics” service. The officially assigned
default port number for RADIUS is 1812.
6. The Information for the Secondary RADIUS Server is optional. This is a mirrored image of the Primary
RADIUS Server and it is used only in case the Primary RADIUS Server fails to respond.
7. Click on the [ Update ] button.
8. Click on the [ Save ] button.
Note:
→
When you factory reset your box, all the RADIUS parameters will be lost.
→
RADIUS users are not cached in the memory. Every time you log on as a RADIUS user,
authentication comes from the RADIUS server.
→
The RADIUS client sends a packet to the RADIUS server and waits for a reply. If it does not
receive a response within 20 seconds, it resends the packet to the same server. If the Primary
RADIUS Server again fails to respond, it contacts the Secondary RADIUS Server, if configured to
do so. If it does not receive a response from the Secondary RADIUS Server, it informs the user
accordingly. Thus, a user may have to wait for as long as 80 seconds if one or both RADIUS
server(s) fail to respond or if the Dominion SX unit is not properly configured.

RADIUS users will appear in the Current users list in the left panel of the main window, but
not in the Users list on the Users configuration screen.
