jeffgraham88,
Maybe you can describe further in detail what you are trying to do. Connecting a switch to a physical port on a controller is routine. Creating a DHCP pool on the controller for that subnet and enabling it so that it gives out addresses is also routine from a switching perspective. If you connect a 3750 with other switching devices, the configuration is the same on both the controller and the 3750. Is there something specific that you are having difficulty with?
