Thanks for the quick answer.

Did you ever find a solution to this? I have had the same problem with two switches, after upgrading to 152-4.E6 with a stack module installed. ... View more

I have seen on post which is kind of similar but that never had an solution https://supportforums.cisco.com/thread/2106901 ... View more

I think I understand the reasoning as to why the promiscuous mode would need to be enabled when used with central switching. However if you use Flexmode with local switching the vWLC management port would only need to be connected to the AP's on the vlan that manages the AP's. The vlan's needed for the various SSID would only be needed at the AP's not the vWLC. Or am I missing something here? ... View more
