Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are to distinguish two entities with the same name but different parameters or parameters that are not the same, see "first" and "second" It is only for the convenience of expression, and should not be construed as a limitation on the embodiments of the present invention, which will not be described one by one in the subsequent embodiments.

The first aspect of the embodiments of the present invention provides an embodiment of a method for filtering DUIDs of non-standard network cards. FIG. 1 is a schematic diagram of an embodiment of a method for filtering DUIDs of non-standard network cards provided by the present invention. As shown in Figure 1, the embodiment of the present invention includes the following steps:

S1, in response to the BIOS update or the first boot after the BIOS is burned, read the DUID information during the BIOS startup process and determine whether the current DUID information is empty;

S2. In response to the fact that the current DUID information is empty, determine the type of the current network card according to the installed PCI protocol and the device type protocol;

S3. In response to the fact that the current network card is a standard PCI network card, the MAC address of the current network card is transferred to the DUID and written into the NVRAM area of the BIOS for permanent storage; and

S4. In response to starting the IPV6 PXE environment, determine whether to perform IPV6 PXE environment installation according to the MAC address of the current network card and the MAC address in the DUID.

Because the BIOS (Basic Input Output System, basic input and output system) and BMC use the Redfish protocol for data interaction and communication, which is actually a physical USB network card, which results in the MAC address of the USB card being stored in the DUID and permanently stored In the NVRAM (Non-Volatile Random Access Memory, non-volatile random access memory) area, the system cannot be installed in the IPV6 PXE environment of the customer data center, and the classification of the network card will be OCP (Open Compute Project Network, Open Compute Project Network) ) and PCI (Peripheral Component Interconnect, Peripheral Component Interconnect Standard) network cards are counted as standard network cards, and other USB interface types of network cards are non-standard network cards. The MAC addresses of non-standard network cards are filtered and the NVRAM area is not permanently saved. Just save the standard network card in the NVRAM area when producing DUID. Considering that the server production line uses IPV4 in the PXE network environment, there is no need to check the matching between the DUID and the MAC address, so the actual standard network card MAC address is passed to the DUID And permanent storage in the NVRAM area can solve the actual IPV6 PXE installation problem in the customer data center.

In response to the BIOS update or the first boot after the BIOS is burned, the DUID information is read during the BIOS startup process and it is judged whether the current DUID information is empty. When the BIOS is updated or the BIOS is burned for the first time, the BIOS will first read the DUID information and determine whether the current DUID information is empty during the BIOS startup process. By default, it is empty, and if it is restarted, there will be a DUID.

In response to the fact that the current DUID information is empty, the type of the current network card is determined according to the installed PCI protocol and the device type protocol.

In some implementation manners, the determining the type of the current network card according to the installation PCI protocol and the device type protocol includes: confirming that the current network card is a standard network card in response to an error message fed back by the installation protocol. When the DUID information is empty, the PCI protocol is installed and judged according to the feedback status value of the installation protocol. When an error message is fed back, it is confirmed that the current network card is a standard network card.

In some implementation manners, the judging the type of the current network card according to the installation PCI protocol and the device type protocol includes: responding to the feedback of the installation protocol that the installation is successful, then continuing to install the device path protocol; responding to the feedback of the device path protocol being error information, then It is confirmed that the current network card is a standard network card; in response to the correct device information fed back by the device path protocol, it is confirmed that the current network card is a non-standard network card. When the feedback protocol is successfully installed, continue to install the device path protocol. If the device path protocol feeds back an error message, confirm that the current network card device is a standard network card device; when the feedback is correct device information, confirm that the current network card device is a non-standard network card device. The MAC address is written to the NVRAM area.

In response to the fact that the current network card is a standard PCI network card, the MAC address of the current network card is transferred to the DUID and written into the NVRAM area of the BIOS for permanent storage. After confirming that the network card information is marked according to the feedback result, write the MAC address of the current network card into the DUID and save it in the NVRAM area of the BIOS. When it is confirmed that the DUID exists, write the DUID into the NVRAM area of the BIOS and save it permanently.

In response to starting the IPV6 PXE environment, determine whether to perform the IPV6 PXE environment installation according to the MAC address of the current network card and the MAC address in the DUID.

In some embodiments, the determining whether to perform IPV6 installation in the PXE environment according to the MAC address of the current network card and the MAC address in the DUID includes: performing an address matching check on the MAC address of the current network card and the MAC address in the DUID, and responding to If the matching results are consistent, the IPV6 PXE environment installation is performed, and if the matching results are inconsistent, the IPV6 PXE environment installation is abandoned. When performing PXE boot to install the system, if the MAC address of the current network card is consistent with the MAC address in the DUID information, the PXE environment installation will be started; if they are inconsistent, the PXE environment installation cannot be started.

In the embodiment of the present invention, whether it is the first BIOS update or the first burning, as long as the BIOS checks that the DUID is empty when the BIOS is turned on, it will judge the type of the currently acquired network card according to the installed PCI protocol and the device type protocol. If it is a standard PCI network card, the network card will be used. The MAC address of the current network card is passed to the DUID and written into the NVRAM area of the BIOS for permanent storage. If it is a non-standard network card, the MAC address of the current network card will be discarded and not passed to the DUID; The MAC address in the DUID is checked for address matching. If the matching results are consistent, the IPV6 PXE environment installation will be performed. If they are inconsistent, the IPV6 PXE environment installation will be abandoned. Through this invention, the MAC address of the USB network card can be filtered to ensure customer data. The security and reliability of the central IPV6 PXE environment.
