RADIUS Account Server Prioritization

Especially useful for customers with multiple SBCs, the RADIUS account server prioritization feature allows you to assign a priority to each of the account servers you configure. Setting the priority for RADIUS accounting servers allows you to load balance traffic across the servers.

Without this feature, the SBC sorts RADIUS accounting servers by their IP addresses and ports. For example, if you have a pre-existing accounting server with the IP address and port combination of 10.1.31.2:1813 and then configure a new server at 10.0.3.12:2145, the new server will take priority over the pre-existing one. Of course, you always have the option of allowing the system to set the priority or your accounting servers in this way.

The prioritization feature works with all of the strategy types you set in the accounting configuration. However, it is most applicable to the hunt or failover strategies. You can assign a number to each server to mark its priority, or you can leave the priority parameter set to 0 (default) so the SBC prioritizes them by IP address and port.
