I am running WCS with 2 WiSM and 4 4404 WLC.
I just turn on CDP on all switches and router for switchport trace features on WCS.
When I tried to turn on CDP on access points I get message to turn on Global CDP features. Problem seem to occur when I tried to turn on cdp on access points that are connect to WiSM. I have no problem with 4404 controllers.
I am running on 18.104.22.168
