Abstract
A system and method includes a first switching device that includes a first control unit with a first and third port coupled to the first control unit and a second switching device that includes a second control unit with the a second port coupled to the second control unit. The system and method may include a network link coupling the first and second switching devices. The first control unit configured to receive a data packet and adding a drop indication. The second control unit configured to detect the drop indication. In some embodiments the first control unit is configured to apply a rule, and mark a data packet with a drop indication in a header, the header being a header normally attached to the data packet. The second switching device may interpret the drop indication with a set of rules to determine a course of action.
