526CHAPTER 22: CONFIGURING COMMUNICATION WITH RADIUS

Configuring Load Balancing

You can configure the WX switch to distribute authentication requests across RADIUS servers in a server group, which is called load balancing. Distributing the authentication process across multiple RADIUS servers significantly reduces the load on individual servers while increasing resiliency on a systemwide basis.

When you configure load balancing, the first client’s RADIUS requests are directed to the first server in the group, the second client’s RADIUS requests are directed to the second server in the group, and so on. When the last server in the group is reached, the cycle is repeated.

MSS attempts to send accounting records to one RADIUS server, even if load balancing is configured.

To configure load balancing, use the following command:

set server group group-nameload-balance enable

For example, to configure RADIUS servers pelican and seagull as the server group swampbirds with load balancing:

1Configure the members of a server group by typing the following command:

WX1200# set server group swampbirds members pelican seagull success: change accepted.

2Enable load balancing by typing the following command:

WX1200# set server group swampbirds load-balance enable success: change accepted.

The following command disables load balancing for a server group:
