--> Link Aggregation (LAG) in the WLC is the way of configuring the Ether channel in switches.
--> LAG simplifies the controller operation by removing the need of configuring the primary and secondary port for each interface.
--> If any of the port in LAG fails, traffic automatically forwarded to other ports in LAG.
--> We can configure LAG during initial configuration or after initial configuration of Wireless Lan Controller.
--> Wireless Controller does not support any dynamic EtherChannel protocols such as LACP and Pagp because no negotiation can be done between wireless controller and switch.
--> Wireless Controller does not answer any negotiation frames and LAG does not form in case of Dynamic EtherChannel Protocols.
--> It is not possible to configure multiple LAG on Wireless Lan Controller.Only one LAG is supported by Wireless Lan Controller.
--> Any changes to Link Aggregation in Wireless Controller requires the reboot.
