The access point uses the secondary accounting server if a failure is detected in the primary accounting server. It continues to use the secondary accounting server until it fails, in which case it returns to sending data to the primary accounting server.

In the RADIUS Authentication section, enter the required parameters for a primary and secondary RADIUS authentication server. When you are finished configuring items, click Apply.

The RADIUS Authentication parameters are described below.

„IP Address—The address of the server.

„Port—The network (UDP) port of the server used for messages. The port defaults to 1812 (1813 for RADIUS Accounting) and must match the port configured on the RADIUS server.

„Key—The encryption key is a shared ASCII string that is used to authenticate logon access for the client. The maximum length is 255 characters. Do not use blank spaces in the string. The key must be configured the same on both the access point and the RADIUS server. The Authentication and Accounting RADIUS servers can have different secret keys.

„Timeout—The number of seconds the access point waits for a reply from the RADIUS server before it resends the request.

„Retransmit attempts—The number of times the access point will try to authenticate logon access.

„RADIUS Servers Assign Client VLAN ID in—Select the VLAN ID format that matches your RADIUS server VLAN ID format.

In the RADIUS Accounting section, click the Enable radio button, then enter required parameters for a primary and secondary RADIUS accounting server. When you are finished configuring items, click Apply.

„RADIUS Accounting Update Interval—This is the interval in seconds between accounting updates sent to the RADIUS accounting server.

„Accounting Log Options—This option controls which clients generate accounting logs. If set to RADIUS Authenticated Clients Only, only those clients that successfully complete 802.1x Authentication will generate accounting logs. The default is for all authenticated clients to generate accounting logs.
