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-name load-balance enable
For example, to configure RADIUS servers pelican and seagull as the
server group swampbirds with load balancing:
1 Configure the members of a server group by typing the following
command:
WX1200# set server group swampbirds members pelican seagull
success: change accepted.
2 Enable 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:
clear server group group-name load-balance
