Abstract

The invention discloses a method for operating a network card MAC address under VxWorks, and belongs to the technical field of computers. According to the method provided by the invention, a muxIoctl interface function in a VxWorks system kernel is utilized, and an EIOCGADDR command and an EIOCSADDR command of the interface are called to read and rewrite the MAC address of the network card, so that the method has high universality and is suitable for all types of network cards; According to the invention, the operation method is simple, reliable and high in execution efficiency, wherein the automatic setting of the network card MAC address when the VxWorks system is started can be completed by setting / modifying the script and the configuration file, separation of MAC address setting / modifying and program codes is achieved, and the maintainability of the system is greatly improved.

Description

technical field [0001] The invention relates to a method for operating the MAC address of a network card under VxWorks, and belongs to the technical field of computers. Background technique [0002] Usually, the operation on the MAC address of the network card under the VxWorks operating system mainly includes reading the MAC address and rewriting the MAC address. Due to the various types of network cards, the MAC addresses of different network cards usually need to be read from different specified I / O addresses, that is, the methods for reading the MAC addresses of different network cards are not uniform. In some specific applications, such as when there are dual redundant network cards in the system, we need to read out the MAC address of one of the network cards, and set the MAC address of the other network card to the same MAC address as it. Contents of the invention [0003] The technical problem solved by the present invention is: overcome the deficiencies in the pr...
