Dears,

This is what I am looking for exactly.Did anyone test these commands in a
real environment?One more thing let us say that the AP is saturated, one
more client tries to join, it will get rejected due to the fact that the AP
is saturated. Will the client automatically attempt to join another AP whose
signal is lower due to the rejection message it got, or will it stick to
re-attempting the join to the same AP.

Guys I really do appreciate your help!

For autonomous AP:

AP# configure terminal
AP(config)# dot11 ssid <ssid ID>
AP(config-ssid)# accounting <AAA accounting method name>
AP(config-ssid)# max-associations <max no>
AP(config-ssid)# vlan <vlan ID>
AP(config-ssid)# exit
AP(config)# interface dot11radio 0
AP(config-if)# ssid <ssid ID>
end
wr

For WLC:

config
load-balancing status enable
load-balancing window <max no>
exit
save config

NOTE
Load balancing is not recommened when having voice over wlan clients
