摘要： A network controller for managing several managed switching elements that forward data in a network that includes the managed switching elements. The network controller is further for creating a logical switching element to be implemented in a set of managed switching elements. The network controller includes a set of modules for receiving input data specifying a logical switching element and for creating, based on the received input data, a set of logical switch constructs for the logical switching element by performing a set of database join operations. At least one of the logical switch constructs is for facilitating non-forwarding behavior of the logical switching element.

摘要： 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.

摘要： Some embodiments provide a method for managing a logical switching element that includes several logical ports. The logical switching element receives and sends data packets through the logical ports. The logical switching element is implemented in a set of managed switching elements that forward data packets in a network. The method provides a set of tables for specifying forwarding behaviors of the logical switching element. The method performs a set of database join operations on the tables to specify in the tables that the logical forwarding element drops a data packet received through a first logical port when the data packet is headed to a second logical port different than the first logical port.
