MAC Address, MAC Address is uniquely, cannot repeat, and there is corresponding MAC Address section in each instrument factory commercial city, and product can only
Using the MAC Address in oneself address field, prevent from conflicting with other equipment vendor product MAC Address.At present MAC Address be all
Mainboard production after, burning is entered one by one, in order to prevent MAC repeat or mistake, to be manually checked, or using script into
Row checks.
Current mistake proofing mode, mainly aims at prevention, and is scanned using scanner to MAC Address sequence number defeated
Enter, then enter mainboard by the way that whether program checkout has duplicate MAC Address to prepare burning on same mainboard.In normal flowing water
In the case of line produces mainboard, such inspection can prevent MAC burning mistake substantially, but need to increase and check program development people
Member.In addition if it is maintenance mainboard needs, artificial burn recording MAC address or terminal user have again burn recording MAC address again
Demand, this preventive inspection just do not work, however these links are also the link for being easier to occur MAC mistake.One
Denier MAC Address has a duplicate conflict in the machine, in use, showing as network performance and stability is declined under system, but
The mechanism that may not significantly report an error is not easy to find so this mistake is easy to be ignored.If manufacturer's MAC Address section is defeated
Enter mistake, misused the address field of other manufacturers, even if conflicting without MAC, but there is the law wind for invading other company properties
Danger.
Summary of the invention
The purpose of the present invention is to provide a kind of inspection modification methods of MAC Address of Network Card, it is intended to solve existing MAC Address
Burning mechanism can not detect the problem of offline rear MAC Address of mainboard changes.
The present invention is implemented as follows: a kind of inspection modification method of MAC Address of Network Card, includes the following steps,
A. initialization step: starting mainboard BIOS simultaneously opens memory source and I/O resource, and sets in the memory source
Set data working area；This working area is the region of memory that software systems are temporarily distributed in program process, for temporarily depositing
Data, program finishes execution are stored up, region of memory will be released, and be used to other programs.
B. read step: BIOS reads MAC Address data in network card equipment memory mapping area and is deposited into the data
Working area；
C. compare step: by the data working area data and nonvolatile storage in data compare and root
According to needing to be modified, revised data are stored in the working area；
D. overwriting steps: revised data recording is entered in the network card equipment memory mapping area and described non-volatile
Property memory block.
E: markers step: if the MAC Address of network card equipment is changed, flag data is generated, and will be revised
Data and flag data send jointly to BMC；
F. show step: the BMC program shows the network card equipment mac address information in BMC administration interface.
It is worth noting that D step and F-step do not need to carry out in strict accordance with the sequence herein, can also first carry out
D step is carried out after F-step again.
Wherein BIOS refers to (Basic Input Output System) basic input output system, is mainly used for calculating
The initialization and detection of various hardware devices in machine start process.
BMC refers to baseboard management controller (Baseboard Management Controller).Generally it is built in mainboard
On, support the IPMI of professional standard to standardize.The function that BMC is provided includes: local and remote diagnosis, console support, configuration
Management, hardware management and troubleshooting.
MAC Address refers to (Media Access Control) media access control address, hardware address, for defining net
The position of network equipment.
IO is the abbreviation of Input/Output, i.e. input/output port.
Under normal circumstances, multiple MAC Address are all continuous dispensings on mainboard.If burning is more than one on mainboard
MAC Address, software can carry out inspection amendment to the MAC Address of non-burning according to the MAC Address value section of burning, if main
For all MAC Address all without burning, software not can determine that the assigned MAC Address section of mainboard on plate, just can not correctly correct, only
One group of default value can be provided, it can be worked, but this class value is likely to conflict with other host MAC address on network.Institute
It is with the precondition that this method is run, at least one the MAC Address burning of the multiple network interface MAC Address of mainboard is completed.
A further technical solution of the present invention is: the step B include it is following step by step:
B1: the MAC Address data of single network card equipment memory mapping area are read；
B2: will indicate the data segment of manufacturer, is compared with the manufacturer data section of preset in advance, judges network card equipment
MAC Address manufacturer data section with it is default whether identical, if it is different, it is substituted for correct manufacturer data section, if identical,
This MAC Address data is stored in data working area；
B3: B1, B2 step are repeated until the MAC Address data of all network card equipments are stored in data working area.
A further technical solution of the present invention is: the step C include it is following step by step:
C1: by MAC Address data in data working area and be stored in advance in nonvolatile storage MAC Address data into
Row compares；If data are identical, without operation；If data are different, C2 is entered step；Data are identical with illustrating network interface card MAC
Location does not need to be operated there is no variation.When BIOS reads MAC data for the first time, there is MAC Address in working area at this time,
Nonvolatile storage data be sky, the result of comparison be then it is not identical, then according to different work step operate.
C2: checking between the data in data working area whether there is repetition, directly that data are temporary if do not repeated
The MAC Address deposited in area covers MAC Address data in the nonvolatile storage；If repeated；Then enter step C3；Network interface card
MAC Address data do not have repeated explanation MAC Address of Network Card to have update but no change has taken place, it may be possible to increase new network interface card
Equipment, MAC Address is stored in nonvolatile storage by us.MAC Address of Network Card data duplicate then there are two types of situation, and first
Kind situation is that burning repeats, and the same MAC Address of two or more network interface card burnings needs to correct；Second situation is
Multiple non-burn recording MAC address of network interface card, the MAC Address area of network interface card are invalid data 0x00 or 0xFF.
C3: Effective judgement is carried out to repeated data, network interface card is set according to default value if repeated data is all invalid
Standby MAC value is configured, and setting is then stored in data working area；If repeated data is valid data, C4 is entered step；
General invalid data is entirely 0x00 or 0xFF, if repeated data be entirely it is invalid, this illustrates that mainboard does not have burning
One group of default value can be set in MAC Address.
C4: according to the principle of arithmetic progression, data are modified, data are then stored in working area.MAC Address tool
There is the characteristics of uniqueness and finiteness, general distribution principle is all to increase to go to distribute one by one.Such as xxx1, xxx2, xxx3,
Xxx4, xxx5 ..., the difference between these adjacent datas are that fixed value 1,2 subtracts 1 and is equal to 1,3 and subtracts 2 and is equal to 1, here it is
Arithmetic progression.The MAC Address of burning mistake is fewer, and it is bigger to correct correct probability, this is because under normal circumstances, it is more on mainboard
A MAC Address is all continuous dispensing.For example, 4 MAC Address xxx1, xxx2, xxx3, xxx4.Software can according to xxx1,
Xxx2, xxx4 accurately infer that the last one MAC is xxx3, and using it as correction value.Software can be pushed away according to xxx2, xxx3
Disconnected remaining two MAC Address are xxx0, xxx1 or xxx4, xxx5 or xxx1, xxx4, then convert software for hardware feature
Algorithm, can maximum probability be positioned as xxx1, xxx4 as correction value.If only knowing a correct MAC Address, then go to infer
Every other MAC, error probability will become larger.
A further technical solution of the present invention is: the step F include it is following step by step:
F1:BMC is polled the order that BIOS is passed over；
F2: judge whether MAC Address of Network Card order after receiving the order that BIOS is passed over, if YES then entering step
F3；
F3: all mac address informations are shown one by one in BMC administration interface.
A further technical solution of the present invention is: the flag data passed in step F according to BIOS is to each MAC
Location information makes different conditions label.
A further technical solution of the present invention is: mac address information data occur for BMC display management interface in step F
Special display is made in change.
A further technical solution of the present invention is: the nonvolatile storage medium is EEPROM.
The beneficial effects of the present invention are: the conventional method for MAC Address of Network Card inspection is puted prevention first with checking before burning,
Method proposes checking scheme after MAC Address burning, can with duplication check is carried out before burning, before burning can also being replaced
Inspection method not only possesses audit function, moreover it is possible to carry out a degree of amendment, can prevent manufacturer's MAC Address core dumped, evade
Legal risk.This method is by first reading MAC Address in BIOS, and MAC Address data are corrected in re-inspection, then write-back MAC Address,
Such thinking is completed to realize, is the differences such as one group on same mainboard according to MAC Address when there is abnormal MAC Address
The principle of column data is completed to correct.The method is realized in BIOS and BMC, on each piece of mainboard, not by technical staff's water
Gentle scene restriction, is automatically performed.BMC administration interface shows MAC Address state, and can warn to user, and user is allowed to carry out core
Real confirmation, makes up the deficiency of debugging functions.
