Here is a guide for you: https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-5/b_WLC_3504_Release_8_5_Deployment_Guide.html#concept_E7054E9C0E404657A6E5C7F6D1EDA9A4

Be aware that you configure mode "on".

Thank you for your fast reply.

Tried that but it didn’t work.

What can I try next?

[Karsten Iwen]

What about describing in detail what didn't work?

Well you can’t use LACP, per the link that was shared

Additionally, LACP and PAgP are not supported on the controller.

Also per the guide:


Configuring Neighbor Devices to Support Link Aggregation

The controller's neighbor devices must also be properly configured to support LAG.

Each neighbor port to which the controller is connected should be configured as follows:

interface GigabitEthernet
switchport
channel-group mode on
no shutdown
The port channel on the neighbor switch should be configured as follows:
interface port-channel
switchport
switchport trunk encapsulation dot1q
switchport trunk native vlan
switchport trunk allowed vlan
switchport mode trunk
no shutdown

Can you explain more what you trying to achieve - and some configuraiton and output which show us that it failed.

how many Link participated in the LAG and port configuration, cisco 3504 (WLC ? )

Look below for some guidelines on how to build LAG.( this gives you some understanding, based on that you can try, still not working post more information, what you have tried and what not working with output logs and config.)

Sorry for the late reply.
Got it working, just been testing.
