This is my setup: Meru wireless controller<->switch1<------->switch2<->AP switch1 & switch 2 are Catalyst 3750 layer 3 switches. The AP communicates with the controller via layer 2. The controller associate the ssid with the DHCP IP addresses from the switch The link between switch 1 and switch 2 is currently a trunk and if I change that link to a routed link. Will the communication between the AP and the controller still work? Thanks
