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 61 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 10 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 20 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.
