Description

MAC address recovery method, device, equipment and storage medium

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a method, an apparatus, a device, and a storage medium for recovering a MAC address.

Background

When a television is produced, the MAC address needs to be burned to uniquely mark the television. However, the burning failure of the MAC address caused by unexpected situations can be encountered during production. For example, the recording process is suddenly powered off, or the error of the normal recording MAC address is caused by the abnormality of the individual core board, or the production line adopts the USB flash disk to upgrade the MAC address, but the USB flash disk is suddenly damaged, and the recording data can not be read.

Taking the burning MAC address of the U disk as an example, before burning, copying a segmented mac.bin file to the U disk, wherein the mac.bin file comprises a plurality of MAC addresses. The USB flash disk is inserted into the USB port of the television A, enters a factory menu, clicks a recording option, and successfully records MAC. The USB flash disk is pulled out and inserted into the USB port of the television B, so that the damaged files of the USB flash disk are lost possibly because the USB flash disk is inserted into the television B at the moment of the problem of a television main board line, or the loss of the USB flash disk is overlarge after the USB flash disk is read and written for many times, and the internal storage medium is damaged to cause the file loss, so that the television B prompts that the mac. Bin file cannot be found and can not be burnt.

When the next MAC address to be burned is determined, if one MAC address is arbitrarily taken for updating, the MAC address may be skipped or reused, which is not only unfavorable for management of the MAC address, but also increases production cost.

It should be understood that the described embodiments are merely some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

The invention is described in further detail below with reference to the attached drawings and detailed description:

Referring to fig. 1 and 2, a first embodiment of the present invention provides a MAC address recovery method, which may be executed by a MAC address recovery device (hereinafter referred to as a recovery device), and in particular, by one or more processors in the recovery device, so as to implement the following steps:

S101, after receiving operation of recovering the MAC address, reading the MAC address of the user and an address burning file stored in a currently connected U disk, wherein the address burning file records a plurality of continuous MAC addresses in a certain address range.

In this embodiment, the recovery device may be a burned device, such as a television. In addition, the recovery device may also be an intermediate device, which is connected to the usb disk and the device to be burned, and obtains information of the usb disk and the device to be burned, so as to implement the MAC address recovery method of this embodiment. In this embodiment, in particular, the device to be burned refers to a tv set that has completed burning normally, i.e. has recorded therein an own MAC address that has been burned.

In this embodiment, before the usb disk is inserted into the recovery device, an address burning file needs to be stored in the usb disk first, where the address burning file is a source mac. Bin file, which refers to a group of files including mac addresses that have been segmented before by mass production devices. One possible mac. Bin file format is as follows:

00 1A 34 BD 93 FF 00 1A 34 BD 94 62

The MAC. Bin file here includes a start MAC address (00 1A 34 BD 93 FF) and a maximum MAC address (00 1A 34 BD 94 62), where each MAC address includes two pieces of information, header information (00 a 34) and address information (BD 93 FF and BD 94 62) representing the manufacturer's code, so that the address range of the MAC. Bin file is from BD 93 FF to BD 94 62.

In this embodiment, after the usb disk is inserted into the recovery device, the recovery device may sense the access of the usb disk and simultaneously display a corresponding interface for a user to operate, for example, the displayed interface may include a recovery burn MAC address option and a recovery MAC address option, and the user may enter a corresponding function by triggering the corresponding option. For example, the user may generate an instruction to recover the MAC address by triggering a recover MAC address option.

S102, judging whether the self MAC address is matched with the address burning file according to the MAC address stored in the address burning file.

In this embodiment, when judging, firstly, header information of the own MAC address is extracted, and whether the header information is consistent with the header information of the MAC address in the address burning file is judged, if so, the header information of the two is judged to be matched. If the information is inconsistent, prompting the unmatched information so that a user can replace the U disk or replace the address burning file.

And then, extracting the address information of the self MAC address, and judging whether the address information is positioned in the address range recorded by the address burning file.

For example, assuming that the own MAC address of the recovery device is 01 1A 34 BD 94 60, since the header information thereof is different from the header information of the MAC address stored in the address burning file, the two do not match.

For another example, assume that the recovery device has its own MAC address 00 1A 34 BD 94 65, and its header information is the same as that of the MAC address stored in the address burning file, but its address information is not within the address range of the MAC address stored in the address burning file, so that the two are not matched.

For another example, assume that the own MAC address of the recovery device is 00 1A 34 BD 94 50, and the header information of the recovery device is the same as the header information of the MAC address stored in the address burning file, and the address information is also in the address range of the MAC address stored in the address burning file, so that the two match.

And S103, when the address is judged to be matched, modifying the initial MAC address of the address burning file mark according to the self MAC address to obtain a modified address burning file, wherein the initial MAC address is the MAC address used by the address burning file in the next burning.

In this embodiment, specifically, after the matching is successful, the recovery device converts the self MAC address into long-integer data, adds a preset hysteresis value to the long-integer data value, generates a recovered MAC address, and modifies the address burning file in a file byte IO stream manner, so that the starting MAC address of the address burning file is the recovered MAC address.

In this embodiment, the hysteresis value is determined according to the recording relationship between the recovery device and the device that fails to record. For example, if the recovery device is the first N devices of the failed device, the hysteresis value is N. In particular, in order to avoid errors, the hysteresis value of the embodiment is preferably 1, that is, the device preceding the device with failed burning is taken as the recovery device.

In this embodiment, taking the hysteresis value equal to 1 as an example, at this time, if the own MAC address of the recovery device is 00 1A 34 BD 94 50, the recovery MAC address is 00 1A 34 BD 94 51. Then the modified address burn file becomes internally 00 1A 34 BD 94 5100 1A 34 BD 94 62.

S104, verifying the initial MAC address of the modified address burning file, and generating a prompt for MAC address recovery after verification is successful.

In this embodiment, after the modification is completed, the recovery device reads the starting MAC address of the modified address burning file again, determines whether the starting MAC address is equal to the recovered MAC address, if so, verifies to pass, generates a prompt for MAC address recovery, and if not, generates a prompt for unsuccessful MAC address recovery.

Referring to fig. 3, in this embodiment, after the MAC address is successfully recovered, the user may pull out the U disc from the recovery device, then insert the U disc into the next device (such as a television) to be burned to burn the MAC address of the television, and the MAC address of the burned television is 00 1A 34 BD 94 51, so that the continuous use of the MAC address is realized, and the problem that the MAC address is skipped or reused is avoided.
