On an OC200 controller, if a site has only two EAP 650 Access Points, powered by a Layer 2 PoE switch (TP-Link), and there is no Omada Router, there is a router from ISP , that manages the DHCP, I understand that the controller, even if it has DHCP enabled in the Wired Networks/LAN section, does not act as a DHCP server because there is no Omada router, is this correct? Can the controller itself provide DHCP in these cases and generate a conflict with ISP's  DHCP?

thanks
