Configuring communication with RADIUS 641
Nortel WLAN—Security Switch 2300 Series Configuration Guide
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.
To configure load balancing, use the following command:
set server group group-name load-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:
WSS# set server group swampbirds members pelican seagull
success: change accepted.
2Enable load balancing by typing the following command:
WSS# set server group swampbirds load-balance enable
success: change accepted.
The following command disables load balancing for a server group:
clear server group group-name load-balance

Adding members to a server group

To add RADIUS servers to a server group, type the following command:
set server group group-name members server-name1 [server-name2] [server-name3]
[server-name4]]
The keyword members lists the RADIUS servers contained in the named server group. A server group can contain
between one and four RADIUS servers. This command accepts any RADIUS servers as the current set of servers. To
change the server members, you must reenter all of them.
For example, to add RADIUS server coot to server group shorebirds:
1Determine the server group by typing the following command:
WSS# show aaa

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