A kind of message processing method that the embodiment of the present invention provides, the method is applied to comprise in the pile system of at least two switching equipment, as shown in Figure 2, the line card on main equipment in this pile system with stacking opening is carried out following step:
S21: receive the message from equipment in pile system with the line card transmission of stacking opening;
, carry virtual destination address in above-mentioned message here, this virtual destination address is mainly used for indicating the line card on main equipment with stacking opening according to this address, to determine the line card of this message of subsequent treatment;
S22: according to the virtual destination address carrying in the message receiving, and the corresponding relation of line card on the virtual destination address of local storage and main equipment, determine line card corresponding to virtual destination address carrying in message;
S23: message is sent to the line card of determining, the line card determined of indication is processed message, and determine whether that according to result the Main Processor Unit that is sent to main equipment processes.
Particularly, in above-mentioned steps S21, from equipment, there is the message that the line card of stacking opening sends, may be from equipment, to there is the message of line card self generation of stacking opening, also may be the message that line card that the line card that has a stacking opening from equipment does not have stacking opening from other obtains, for example, other line cards without stacking opening can transmit message by internal data link.
In other words, for above-mentioned message, its source line card not merely refers to have from equipment the line card of stacking opening, likely also from equipment, not there is the line card of stacking opening, no matter which kind of line card this message derives from, the virtual destination address carrying in this message is in fact all that the Main Processor Unit by main equipment that message source line card receives passes through one of pre-configured virtual destination address forwarding from the Main Processor Unit of equipment.
It should be noted that, in embodiments of the present invention, the Main Processor Unit of main equipment can be main management plate, be provided with a plurality of virtual destination addresses in advance, for example virtual destination address can be virtual switch chip number (CIHPID), and, in the Main Processor Unit side of main equipment, also dispose the corresponding relation of line card on these virtual destination addresses and main equipment, the line card that these virtual CHIPID are corresponding can be all on main equipment, not have the line card of stacking opening, also can be partly on main equipment, not there is the line card of stacking opening, the Main Processor Unit of main equipment can be by pre-configured corresponding relation, be handed down to the line card on main equipment with stacking opening, that is to say, under the Main Processor Unit that the local corresponding relation of storing of line card on main equipment in above-mentioned steps S22 with stacking opening is main equipment, send, so that there is the corresponding relation that the line card of stacking opening receives according to this on main equipment, the message receiving is shunted to processing.
