Description
Technical Field
The invention relates to the technical field of communication, in particular to a method for automatically updating an MAC address.
Background
At present, embedded devices have various methods for generating MAC addresses, for example, unique addresses of chips are used, but in actual work, it is found that chip addresses cannot guarantee uniqueness, and repetition occurs at a certain probability. The method adopts a unified algorithm and a unified protocol, realizes updating automation and ensures the uniqueness of the MAC address of the equipment.
Disclosure of Invention
The invention aims to provide a method for automatically updating MAC addresses.
In order to achieve the purpose, the invention adopts the following technical scheme:
there is provided a method of automatically updating a MAC address, the network device comprising an automatic updating means, a program initializing means and a connecting means,
the program initialization device is used for initializing the MAC address of the equipment to become a specific address and setting a default IP address;
the connecting device is connected with the equipment and accesses the equipment to the network, and the automatic updating device is connected with the equipment and is used for searching and connecting an IP address and acquiring the MAC address of the equipment; the method for automatically updating the MAC address comprises the following steps:
firstly, initializing a device program, and initializing a specific MAC address and a default IP address;
starting network service, networking equipment, automatically updating a device to search an IP of the equipment and automatically connecting to obtain an MAC address of the equipment;
judging whether the equipment MAC address is the same as the specific MAC address, if so, generating a new MAC address, and then comparing the new MAC address with the specific MAC address until generating a non-repeated MAC address;
and updating the MAC address of the device until the device finishes updating.
Further, after the network service is started by the connecting device, the IP address of the device to be connected is automatically updated, and if the device cannot be connected, the connection is repeated until the connection is successful.
Further, after the automatic updating device obtains the device MAC address, if the device MAC address is different from the specific MAC address, the device MAC address does not need to be updated.
Further, the automatic updating device generates a new MAC address, but if the updating of the MAC address of the apparatus is unsuccessful, the updating procedure is restarted, and if the continuous updating fails for 3 times, the apparatus determines that the defective item is rechecked.
The invention has the beneficial effects that: the method for automatically updating the MAC address sets a unified algorithm and a unified protocol through the automatic updating device, sets a unique address for the chip, ensures the uniqueness of the chip address and avoids the occurrence of the repeated phenomenon of the chip address; and the repeated MAC addresses are automatically updated and debugged, so that the uniqueness of the MAC addresses of the equipment is ensured.
Drawings
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings in the embodiments of the present invention are briefly described below.
FIG. 1 is a flow chart of the automatic MAC address update according to the embodiment of the present invention;
Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; to better illustrate the embodiments of the present invention, some components of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product.
Referring to fig. 1, a method for automatically updating a MAC address, the network device includes an automatic updating device, a program initializing device and a connecting device, the program initializing device is used for initializing a device MAC address to a specific address and setting a default IP address; the connecting device is connected with the equipment and accesses the equipment to the network, and the automatic updating device is connected with the equipment and is used for searching and connecting an IP address and acquiring the MAC address of the equipment; the method for automatically updating the MAC address comprises the following steps:
firstly, initializing a device program, and initializing a specific MAC address and a default IP address;
starting network service, networking equipment, automatically updating a device to search an IP of the equipment and automatically connecting to obtain an MAC address of the equipment;
judging whether the equipment MAC address is the same as the specific MAC address, if so, generating a new MAC address, and then comparing the new MAC address with the specific MAC address until generating a non-repeated MAC address;
and updating the MAC address of the device until the device finishes updating.
The working principle is as follows: the method is mainly applied to software of embedded equipment, instructions of reading and writing the MAC address of the equipment are unified, the equipment address is initialized to a specific address, a default IP address is set at the same time, then the equipment is accessed into a network, an automatic updating program can automatically search the IP, if the IP is found, an automatic updating device can automatically connect the IP to obtain the MAC address of the equipment, and if the MAC address of the equipment is the same as the specific MAC address, the MAC address is updated. Firstly, generating an MAC address which cannot be repeated according to a rule, and finally updating the equipment MAC address to finish the updating of the equipment MAC address.
After the network service is started by the connecting device, the IP address of the device needing to be connected is automatically updated, if the connection cannot be carried out, the connection is repeated until the connection is successful, and when the connection of the IP address is unsuccessful, the connection is tried again by considering the reasons of program initialization failure or network obstruction and the like, the program is reinitialized again or the network is reconnected until the IP is connected and the device information is obtained.
After the automatic updating device acquires the equipment MAC address, if the equipment MAC address is different from the specific MAC address, the MAC address does not need to be updated, and if the MAC address acquired for the first time is different from other specific MAC addresses, a new MAC address does not need to be generated and does not need to be updated.
And the automatic updating device generates a new MAC address, but the updating of the equipment MAC address is unsuccessful, the updating program is started again, if the continuous updating fails for 3 times, the equipment judges that the defective product is rechecked, and after the new MAC address is generated, the equipment MAC address is automatically updated, but the continuous updating still fails for 3 times, the equipment problem is considered, and the program defines the equipment as the defective product to be rechecked.
