This command configures the load balancing algorithm used by the RADIUS client to manage authentication and accounting requests sent to configured RADIUS servers. Load balancing configuration is configured for a group of RADIUS servers or global default RADIUS server group. A server group is identified as a group of RADIUS servers using the same configured server name.
The supported load balancing method is based on the least number of outstanding requests. In this mode, the RADIUS client selects a configured RADIUS server that has the least number of pending requests. Before selecting a new server, the number of pending requests on the current server in use should be more than configured batch size value.
