we have a wlc 5508 and lwap 1142
lwap 1142 have join wlc 5508 with ver AIR-CT5500-K9-7-0-116-0
I upgrade wlc version AIR-CT5500-K9-7-0-220-0
and lwap no long join wlc, on wlc debug I get:
Discovery Request received on wrong VLAN '114' on interface '13', management VLAN = '99', AP Manager VLAN = '99', dropping the packet
wlc hasnt got interface 13. and I see wlc hasnt got port config in in interface vlan config GUI.
I have seen the same problems:

So the solution: ap-manager vlan and management vlan in same subnet
But why does wlc suddently change the way it use the managent ap-manager and management vlan ?
Thanks
