To enable LAG (Link Aggregation) use the command :

Save the config and reboot the WLC.
To verify if LAG is enable on the WLC :
(Cisco Controller) >show lag summary

The config for the switches should be :
interface GigabitEthernet1/0/1

channel-group 1 mode on
end

and don’t forget :
interface Port-channel1
description 4404 LAG
switchport trunk encapsulation dot1q
switchport trunk native vlan 5

end

The preferd method for loadbalancing is :
SW3750E(config)#port-channel load-balance src-dst-ip
