Setting strictness for RF load balancing
To perform RF load balancing, AP radios with heavy client loads are less visible to new clients, and causes the new
client to associate with AP radios with a lighter load.
You can specify how strictly WSS attempts to load balanced across the AP radios in the load-balancing group. When
low strictness is specified (the default), heavily loaded AP radios are less visible and steer clients to less-busy AP radios,
while ensuring that clients are not denied service even if all the AP radios in the group are heavily loaded.
When maximum strictness is specified and if an AP radio has reached the maximum client load, the AP radio is invisible
to new clients and clients attempt to connect to other AP radios. In the event that all the AP radios in the group reach
maximum client load, then no new clients can connect to the network.
To specify load balancing strictness across the AP radios in a load-balancing group, use the following command:
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 APs, 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 APs and clients attempting to connect
to overloaded radios may be delayed several seconds.
• When the high option is set, overloaded radios steer new clients to other APs and clients attempting to connect
to overloaded radios may be delayed up to a minute.
• When the max option is set, RF load balancing is strictly enforced. Overloaded radios do not respond to new
clients at all, and a client cannot connect during times that all of the detectable AP radios are overloaded.
