Abstract
This invention discloses a method for obtaining the MAC address of a device including: 1, designing the position ID of a physical position ID unit of a device, 2, turning on the device, 3, fetching the physical position ID information by a hardware logic and writing it in a register, 4, a MAC address generating unit takes the plant number of the device as the prefix and combines it with the physical position ID information in the register to generate the MAC address of the device, 5, the generating unit reports the generated address to the address resource management unit of the system to register it and judges if there is conflict to the MAC address, 6, returning to the first to reset the physical position ID if so, otherwise, it's over, which gets the MAC address when a device is turnedon automatically.
Description
Technical field
The present invention relates to the equipment addressing of communication, electronic applications, in particular to a kind of method of obtaining device mac address.
Background technology
In the network based on the IP communication, the network equipment must dispose MAC Address just can carry out normal communication.Current at present device mac address production method is: the manufacturer that produces the network equipment buys one section MAC Address to the IEEE application, and MAC Address is burnt in the equipment, just can obtain the MAC Address of oneself after the device power by the content that reads burning.Because MAC Address must be unique, cause the program that in device fabrication, needs burning different, this just is unfavorable for large-scale production, and in a single day MAC Address is solidificated in the equipment in addition, and just inconvenience is revised, and lacks flexibility.
Summary of the invention
Purpose of the present invention is exactly the method for obtaining device mac address that helps the applying flexible of large-scale production.
A kind of method of obtaining device mac address is characterized in that comprising the following steps:
The first step, the station location marker of devices'physical locations identify unit is set;
Second step, device power;
The 3rd step, hardware logic read the physical location identification information, and write register;
The 4th step, device mac address generation unit with instrument factory trading company as prefix, with the MAC Address of physical location identification information in register combination generation equipment;
The 5th step, device mac address generation unit report the system address rm-cell with the device mac address that generates, and the MAC Address conflict is registered and judged whether in the address resource management unit to device mac address;
Return the first step if there was the MAC Address conflict in the 6th step and reset the physical location sign; Otherwise finish.
The method that the present invention proposes cooperates by software and hardware when device power, obtains MAC Address automatically, and method is simple, can not cause the software version difference of equipment because of the reason of MAC Address, helps production line large-scale production.And when needs are revised device mac address,, give device power again as long as change the physical location sign, just can change device mac address.
Description of drawings
Fig. 1 is the flow chart of the method that proposes of the present invention.
Embodiment
Further describe the present invention below in conjunction with drawings and Examples.
The realization of the method that the present invention proposes relates to the address resource management unit of devices'physical locations identify unit, MAC Address generation unit and system, is described below respectively:
The physical location identify unit: the physical location of marking equipment in network, as the unique identification of equipment.In order to distinguish the miscellaneous equipment in the network, as the foundation that constitutes MAC Address, avoid taking place the MAC Address conflict with this.The physical location identify unit is in order to distinguish each equipment, in network, must keep uniqueness, can be by the realization of leaving behind on toggle switch or the resistance, toggle switch or resistance several sections be can be divided into, network element, frame, machine frame, groove position or expression province, city, district, office represented respectively.Read sign by logic after powering on and be kept in the register, read for the MAC Address generation unit;
MAC Address generation unit: according to the information that the physical location identify unit provides, generate the MAC Address of equipment, and MAC Address is reported the address resource management unit.
Address resource management unit: receive mac address information,, avoid taking place address conflict in order to MAC Address in registration, the whole network of management from the MAC Address generation unit.If exist conflict to need alarm to give the user.
As shown in Figure 1, the method for the present invention's proposition comprises the following steps:
The first step, the station location marker of devices'physical locations identify unit is set.Draw and drop-down realization on break-make that can be by toggle switch is set or the resistance.
Second step, device power.
The 3rd step, hardware logic read the physical location identification information, and write register.The hardware logic here is meant EPLD or the CPLD or the FPGA of physical location identify unit the inside, and the inside burning program can move after powering on.
The 4th step, device mac address generation unit with instrument factory trading company as prefix, with the MAC Address of physical location identification information in register combination generation equipment.The device mac address generation unit at first will read the trading company of factory of MAC Address, and trading company of factory is bought to IEEE by manufacturer, and as the prefix of MAC Address, trading company of factory can be solidificated in the program, makes up after reading the physical location identification information then from register.For example: trading company of factory is 00-D0-D0, and the physical location sign is 16bit, and the information that reads from register is 1F-58, and then MAC Address can be 00-D0-D0-00-1F-58.
The 5th step, device mac address generation unit report the system address rm-cell with the device mac address that generates, and the MAC Address conflict is registered and judged whether in the address resource management unit to device mac address.
Return the first step if there was the MAC Address conflict in the 6th step and reset the physical location sign; Otherwise finish.If there is the MAC Address conflict, then must resets the physical location sign and generate new MAC Address.
Claims (4)
1. a method of obtaining device mac address is characterized in that comprising the following steps:
The first step, the station location marker of devices'physical locations identify unit is set, the station location marker of devices'physical locations identify unit perhaps is set with province, city, district's drawn game with network element, frame, machine frame and groove position;
Second step, device power;
The 3rd step, hardware logic read station location marker information, and write register;
The 4th step, device mac address generation unit as prefix, generate the MAC Address of equipment with station location marker information combination in the register with instrument factory trading company;
The 5th step, device mac address generation unit report the system address rm-cell with the device mac address that generates, and the MAC Address conflict is registered and judged whether in the address resource management unit to device mac address;
If there was the MAC Address conflict in the 6th step then returned the first step and reset station location marker; Otherwise finish.
2. method according to claim 1 is characterized in that described physical location identify unit realizes with toggle switch.
3. method according to claim 1 is characterized in that described physical location identify unit is with the realization of leaving behind on the resistance.
4. according to claim 1 or 2 or 3 described methods, it is characterized in that the trading company of factory of equipment in described the 4th step is solidificated in the program.
