Abstract:
1. A method for managing a logical forwarding element comprising a plurality of logical ports through which the logical forwarding element receives and sends data packets, the logical forwarding element implemented in a set of managed forwarding elements that forward data packets in a network, the method comprising: determining that port isolation has been enabled for the logical forwarding element; and performing a set of database join operations on tables of a set of tables for specifying forwarding behaviors of the logical forwarding element, the tables comprising a set of high priority tables for enabling port isolation, wherein the logical forwarding element processes data according to a set of forwarding behaviors specified in the set of high priority tables over forwarding behaviors specified in tables other than the high priority tables, the join operations 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 addressed to a second logical port different than the first logical port to implement the port isolation, wherein the set of tables are for translation into a set of physical forwarding rules to implement the forwarding behaviors of the logical forwarding element on the set of managed forwarding elements, wherein the determining and the performance of the set of database join operations are performed by an electronic device.
