An information handling system is provided. The information handling system includes at least one server, that includes a plurality of ports, wherein information is transmitted to and from the at least one server on the plurality of ports, and a memory storing a table, the table storing a status indication and port on which the status indication was received. The information handling system also includes a plurality of switches coupled to the at least one server to form a link aggregation group (LAG), the plurality of switches transmitting information including the status indication to the at least one server. If the server receives more than one status indication having a master status, the at least one server is configured to stop forwarding information on at least one port on which information including a master status indication has been received after previously receiving information that did not include a master status indication.

A method for fault tolerant controller readiness. Executing functions by a first controller operating in a primary status mode. Operating in a hot standby status mode by a second controller and mirroring the first controller by executing functions to operate as a redundant controller. Operating in a cold standby status mode by at least one backup controller under normal operating conditions. The second controller is reconfigured while operating under normal operating conditions from the hot standby status mode to the primary standby status mode if a failure occurs in the first controller. Reconfiguring the at least one backup controller operating under normal operating conditions from cold standby status mode to hot standby status mode to operate as a redundant controller in response to the reconfiguring the second controller from the hot standby status mode to the primary status mode.

The invention discloses an Ethernet communication master station implementation method, comprising an Ethernet, a master station and a slave station, wherein the master station is connected with the Ethernet by a connector, and forms a bus structure with the slave station which is connected with the master station by the Ethernet; the method specifically comprises the following steps: a initializing the master station and scanning the bus, b configuring the bus and synchronously monitoring the real-time state of the bus, and c entering to the normal running stage by the bus so as to finish data communication work between the master station and the slave station. The method has beneficial effects that the master station can dynamically adjust the instruction sending time according to system task scheduling jitter and application program execution time jitter, so as to ensure the consistency of the rhythms of the master station and the slave station in reading and writing data, the real-time requirement of the method to the master station is not very high, and the allowed system task scheduling jitter is larger and larger along with the shortening of the execution time of the upper application program.
