and when the network segment information corresponding to the BMC140 is not matched with the second network segment information, forwarding the management data packet to the PCIe switching module 120.
It should be noted that, when data needs to be acquired from the service platform through the management platform, the management platform needs to establish a connection with the service platform, after the BMC portal 141 sends the management data packet to the BMC140, the BMC140 needs to parse the management data packet and acquire second network segment information corresponding to the management data packet, match the second network segment information with the network segment information of the BMC140 itself, if the matching is successful, continue to process the service data packet, and if the matching is not successful, forward the management data packet to the PCIe switching module 120.
