Port security in some embodiments is a technique to apply to a particular port of a logical switching element such that the network data entering and existing the logical switching element through the particular logical port have certain addresses that the switching element has restricted the logical port to use. For instance, a logical switching element may restrict a particular logical port to one or more certain network addresses. To enable a logical port of a logical switch for port security, the control application of some embodiments receives user inputs that designate a particular logical port and a logical switch to which the particular logical port belongs. The control application in some embodiments formats the user inputs into logical control plane data specifying the designation. The control application in some embodiments then converts the logical control plane data into logical forwarding data that specify port security functions.
