A method for resolving split conditions in a port-extended network comprises receiving first information indicative of a first MAC address of a first controller on a first fabric link and second information indicative of a second MAC address of a second controller on a second fabric link. The method may also include determining that the first MAC address differs from the second MAC address and responsively determining that one of the first MAC address or the second MAC address was previously associated with a primary controller of the port-extended network. One of the first controller or the second controller is designated as the primary controller of the port-extended network based on the determination that one of the first MAC address or the second MAC address was previously associated with the primary controller.
