Abstract:
1. An information handling system, comprising: a plurality of aggregation devices configured to distribute information in a virtual link trunk, each of the aggregation devices comprising a processor and memory; a plurality of nodes coupled to the aggregation devices, wherein when one of the plurality of aggregation devices receives a reboot command, the processor of the one of the plurality of aggregation devices is configured to: transmit a corresponding first message to each of the plurality of nodes, the corresponding first message having a protocol field set to indicate that the one of the plurality of aggregation devices is rebooting; receive a corresponding first acknowledgement message from each of the plurality of nodes, the corresponding first acknowledgement message having a protocol field set to indicate that a corresponding one of the plurality of nodes will not send any information to the one of the plurality of aggregation devices and is still receiving information from the one of the plurality of aggregation devices; reboot the one of the aggregation devices after receiving the corresponding first acknowledgement message from each of the plurality of nodes; receive a corresponding second message from each of the plurality of nodes, the corresponding second message having a protocol field set to indicate that the corresponding one of the plurality of nodes is ready to receive information from the one of the plurality of aggregation devices and will not be transmitting information to the one of the plurality of aggregation devices; transmit a corresponding second acknowledgement message to each of the plurality of nodes after receiving the corresponding second message from each of the plurality of nodes, the corresponding second acknowledgement message having a protocol field set to indicate that the one of the plurality of aggregation devices has rebooted and will receive information; and receive information from at least one of the plurality of nodes for transmission to at least one other node of the plurality of nodes.
