D-Link Unified Access System Software User Manual 12/10/09 Table 248: RADIUS Configuration Fields (Cont.) Field Number of Configured Accounting Servers Number of Named Authentication Server Groups Number of Named Accounting Server Groups Max Number of Retransmits Timeout Duration (secs) Accounting Mode RADIUS Attribute 4 (NAS-IP Address) Description The number of RADIUS accounting servers configured on the system. The value can range from 0 to 32. The number of authentication server groups configured on the system. An authentication server group contains one or more configured authentication servers that share the same RADIUS server name. The number of accounting server groups configured on the system. An accounting server group contains one or more configured authentication servers that share the same RADIUS server name. The value of the maximum number of times a request packet is retransmitted. The valid range is 1-15. Consideration to maximum delay time should be given when configuring RADIUS max retransmit and RADIUS timeout. If multiple RADIUS servers are configured, the max retransmit value on each will be exhausted before the next server is attempted. A retransmit will not occur until the configured timeout value on that server has passed without a response from the RADIUS server. Therefore, the maximum delay in receiving a response from the RADIUS application equals the sum of (retransmit times timeout) for all configured servers. If the RADIUS request was generated by a user login attempt, all user interfaces will be blocked until the RADIUS application returns a response. The timeout value, in seconds, for request retransmissions. The valid range is 1 - 30. See the Max Number of Retransmits field description for more information about configuring the timeout duration. Use the menu to select whether the RADIUS accounting mode is enabled or disabled on the current server. To set the network access server (NAS) IP address for the RADIUS server, select the option and enter the IP address of the NAS in the available field. The address should be unique to the NAS within the scope of the RADIUS server. The NAS IP address is only used in Access-Request packets.
