Setting Strictness for
RF Load Balancing
To perform RF load balancing, MSS makes MAP radios with heavy client
loads less visible to new clients, causing them to associate with MAP
radios that have a lighter load.
loads less visible to new clients, causing them to associate with MAP
radios that have a lighter load.
You can optionally specify how strictly MSS attempts to keep the client
load balanced across the MAP radios in the load-balancing group. When
low strictness is specified (the default), MSS makes heavily loaded MAP
radios less visible in order to steer clients to less-busy MAP radios, but
ensures that even if all the MAP radios in the group are heavily loaded,
clients are not denied service.

radios less visible in order to steer clients to less-busy MAP radios, but
ensures that even if all the MAP radios in the group are heavily loaded,
clients are not denied service.
At the other end of the spectrum, when maximum strictness is specified,
if a MAP radio has reached its maximum client load, MSS makes it
invisible to new clients, causing them to attempt to connect to other
MAP radios. In the event that all the MAP radios in the group have
reached their maximum client load, then no new clients would be able to
connect to the network.

To specify how strictly MSS attempts to keep the client load balanced

set load-balancing strictness {low | med | high | max}
When the low option is set, no clients are denied service. New clients
can be steered to other MAPs, but only to the extent that service can
be provided to all clients. This is the default.

When the med option is set, overloaded radios steer new clients to
other MAPs more strictly than the low option. Clients attempting
