I am having the same issue I can access the WLC if there is no VLAN tagging on the WLC. Without VLAN tagging I can connect to and manage the switch, but I can't get any APs to join to it. As soon as I tag the interfaces I lose the ability to connect to them the WLC. The APs are on the same VLAN as the WLC and I have tried both DHCP and Static addressing for the APs and neithe works.
I have no firewalls between any of these devices and no ACLS on the VLANs in question.
I have the IP addresss set as
ap manager 10.250.21.253 VLAN 12
management 10.250.21.254 VLAN 12
service is 192.268.151.1
I can't get any more info right now cuz I tried setting the VLAN again since no aps could join and I can't access it by the network will have to connect to the service port again.
Here is what I have set for the switchport it connects to:
