In the event of a failover of the main RADIUS server—if there is no response after
the set number of retries—then the other servers in the list will be polled on a
round-robin basis until a server responds.
If one of the other servers becomes the active server during a failover, when the
new active server properties are displayed the Set as primary server checkbox
is selected.
If all defined RADIUS servers fail to respond, a critical message is generated in
the logs.
To define the RADIUS server priority for RADIUS redundancy:
1. From the main menu, click Virtual Network Configuration. The Virtual
Network Configuration page is displayed.
2. In the left pane Virtual Networks list, click the VNS you want to define the
RADIUS server priority for. The Topology tab is displayed.
3. Click the Auth & Acct tab.
4. From the drop-down list, click the servers group you want to prioritize:
• Configured Servers
• Authentication Servers
• MAC Servers
• Accounting Servers
5. In the server list, click the RADIUS server and then click Up or Down to
arrange the order. The first server in the list is the active one.
6. To test the HiPath Wireless Controller’s connection to all configured RADIUS
servers, click Test. The Test RADIUS servers page displays the message
transaction with the RADIUS server, which allows you to visually verify the
state of the server connection and user authentication.
The RADIUS test is a test of connectivity to the RADIUS server, not of full
RADIUS functionality. AAA VNSs use EAP over RADIUS for authentication.
The HiPath Wireless Controller’s EAP RADIUS connectivity test initiates an
Access-Request, to which the RADIUS server will respond with a challenge.
If the challenge is received then the test is deemed to have succeeded. If the
challenge is not received then the test is deemed to have failed. In either
case, the test ends at this point; for AAA VNSs, there is no need for a client
password below.
7. In the User ID box, type the user ID that you know can be authenticated.
8. In the Password box, type the corresponding password.
9. Click Test. The Test Result page is displayed.
