INSTRUCTIONS: [Technical Field of the Invention] A test system, in particular, refers to a test system and method for testing at least one host by batch using a local loop to establish a substrate management control connection. [Prior Art] The Intelligent Platform Management Interface (IPMI) is an integrated remote hardware management standard developed by the industry. It defines a common platform detection interface for improving the relationship between the motherboard and the host computer. Interoperability between the motherboard and the server management software, and even between the server and the server. The definition and scope of the positive cover include software, firmware, and hardware. In short, the main purpose of Zhengying is to provide a layered management architecture based on modular design, which provides management for each layer of integration, including software, hardware and firmware, from the processor, chipset, The BIOS, the components to the motherboard, etc. are all in the scope of jpjyjj management. Positive New Zealand First, plan the sensing and monitoring system in the device and equipment. One way to implement this is to use the Baseb〇arcj Management Ccmtrollei* BMC as the monitoring system. The BMC can be the daughter card (or adapter card) on the motherboard, 5 for the main management of the main oil department. Various types of work in the system, such as monitoring whether the system is functioning properly, and making system records. At present, the BMC is used for pre-i testing of computers or electronic devices. The practice is to install the BMC in the computer under test (hereinafter referred to as the host), connect to a subnet, and each to the BMC and the host. Network card (9) coffee her coffee ^ plus NIC) set the network her. After setting the network comma, the user can use the remote access method to connect to the BMC and the host through the subnet, and then establish the connection of the disk master 200826592 and configure the host to configure the BMC. Figure 1 is a schematic diagram of connecting a host to a BMC through a subnet. Referring to the first diagram, the NIC 112 of the host 11 以及 and the NIC 122 of the BMC 120 inside the host are respectively given a physical address of 10·10·0·2 and 1〇·1〇·〇.ι, and these Accessing a subnet; performing the same steps on the other host 130 and its internal BMC 140, and setting the respective NICs (132 and 142) to io.io q 4 and 1〇·1〇·〇· 3, and will be connected to the s^ic, the above subnet. After that, the remote client 150 starts the host 110 through the address ι0·10·0·2 to set the parameters of the BMC, and causes the host to connect to the BMC through the address 1〇1〇〇1, and the same host 13〇 also uses a similar The steps complete the setup and establish a connection for the host to test. Such practices often take a lot of time in the erection and configuration of the local area network, and when the regional network is set up, the address configuration of each host may affect the test results. For example, when testing one host at the same time, if the network functions of the two hosts are the same and the network function of the host is not available, the test result may be reported as two hosts. Damaged host. In addition, due to the limited number of subnet addresses, for example, a sub-network segment of the same level C can test up to 128 hosts at the same time, and it is impossible to perform batch test of a large number of hosts.

[Embodiment] In order to make the above-mentioned and other purposes, miscellaneous and superior positions of the present gamma more understandable, the following describes the embodiment 'in conjunction with the _ formula, and the following is a detailed description. The second figure is the implementation of the present invention. The local scale construction domain board tube = ^ tear system diagram. Please refer to Fig. 2, the measurement of the 犹 糸, 福 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县 县To control the host side. In this implementation, the system includes at least a host (in the present embodiment, the host terminals 21 and 230), and each of the host terminals has a chip management controller (10) inserted therein. To verify the functions of the host side before the host side is out of the line. The host side (10) or 23__ is each equipped with a network 2, called) and a network card (232, _), and the network card 232 is a network card used for the baseboard management controllers 22G, 240 (222, 242) Establish a baseboard management controller connection 'host end 2K', 23 〇 according to this connection through the substrate management controller 220, 240 to perform functional tests before leaving the factory. The other network card 214, 234 of the host terminal 21〇, 23〇 is used to form a test connection with the remote client terminal 15 and communicate the test result to the remote user through the 200826592 il test connection. . The so-called base management controller connection is to establish a connection to the baseboard management controller for testing the host. In this embodiment, the host side (21〇 and now) respectively, the corresponding baseboard management controller (10) and The connection is a loop test connection, and fl says earlier that it is a line connection between the baseboard management controller (22〇 and 24〇) and the host terminals (10) and 230), similar to the loop. Test the way to test. The remote client 150 and the network card 214 of the host 210 (the test connection of the network card of the host 23〇, the host terminal (10), 23〇) and the corresponding substrate management] cry (10), 2, Zhao Zhao virtual her, For example, the slave is for the financial health (prJat^'s section of the muscle lake grabs 192. 255.255 one of the network addresses, after the completion of the determination, use these virtual addresses to establish a loop test connection.

She said that the _ multiple host _ virtual address of the way The multi-control controller forms a regional network that does not interfere with each other, and establishes a - loop test = connection, testing the machine in a manner similar to internal loop test, because Compared with the prior art, the present invention has the following advantages: (1) When multiple host terminals of the 2-subnetwork are simultaneously tested with the corresponding substrate government controller, the URL duplication problem does not occur, and the test is affected. As a result, (2) each host can form a zone _ path with the corresponding baseboard management controller to perform batch 峨, thereby saving the time of the machine test. (3) avoiding the physical position in the same network The problem of depletion of address resources. Although the foregoing preferred embodiment of the present invention (10) is as described above, the invention is not limited to the spirit and scope of the present invention. 'The change of the fascination is the scope of the special beauty protection of the present invention. Therefore, the patent loyalty ill of this month shall be subject to the definition of the scope of the patent attached to this manual.
