Can you check to ensure you have LAG enabled on the WLC?
Also, can you check the switch to ensure ports Gi1/0/4 and Gi2/0/16 are part of the same Port channel group?
Possibly post configs of the switch interfaces and the portchannel interface.
Sounds to me like a portchannel is not forming between the switch and the WLC so the switch is recieving frames with the same source MAC from both interfaces and it can't handle this if they are not part of a portchannel.
The ports on the Core (Gi1/0/4) and (Gi2/0/16) are not in any sort of Port Channel They are just acting as individual ports. I assume they should form an etherchannel. This is fine, I can configure this.
On the WLC itself - how can i check if the ports are enabled for LAG. Commands seem to be a bit different on the WLC IOS.
