(5) abandon described MAC Address configuration packet, continue to receive the MAC Address configuration packet, return step (4);

(6) veneer upgrades the MAC Address of veneer according to the MAC Address configuration packet that receives.

Wherein, described step also comprises:

(A) master control borad generates mac address table, comprises the MAC Address of each port of switching network in the described mac address table;

(B) master control borad is each port arrangement MAC Address of inner exchanging net according to mac address table.

Wherein, comprise in the MAC Address configuration packet described in the step (2): the target MAC (Media Access Control) address of described MAC Address configuration packet, configuration packet flag information, configuration packet check information.

Wherein, step (4) is specially:

The ethernet controller of veneer reads configuration packet flag information and the configuration packet check information in the MAC Address configuration packet, judge whether described configuration packet flag information and configuration packet check information be legal, if it is legal, then the ethernet controller of veneer is set to be operated in normal mode, and enter step (6), if illegal, then enter step (5).

Wherein, described step (6) is specially:

Veneer reads the target MAC (Media Access Control) address in the described MAC Address configuration packet, and described MAC Address is configured to the MAC Address of veneer.

The method of each node configuration MAC Address in the inner exchanging net that the present invention proposes, overcome the shortcoming such as realization complexity, consumes resources, modification inconvenience, poor expandability of prior art, by master control borad the MAC Address of other peripheral single board is carried out centralized control and distribution, need on veneer, not increase extra memory, do not need to increase the backboard cabling yet, when the generating algorithm of MAC Address changed, the software that only needs to change on the master control borad gets final product, and was very flexible.This method also has very strong extensibility in addition, can add other Useful Informations as required and obtain for peripheral single board in configuration packet, as the IP address of peripheral single board, MAC Address and IP address, the routing iinformation etc. of master control borad.
