For a logical switching element implemented across several managed switching elements, some embodiments provide a method that receives a packet for processing through the logical switching element. The method performs a set of logical forwarding operations for determining a particular destination at the logical switching element to forward the packet. Based on the particular destination at the logical switching element, the method performs a set of physical forwarding operations for determining a destination at a managed switching element of the several managed switching elements that corresponds to the particular destination at the logical switching element. The method forwards the packet to the destination at the managed switching element.
