A message processing method, line card and switching device

Abstract

The embodiment of the invention provides a message processing method, a line card and switching equipment. The method is applied to a stacking system including at least two pieces of switching equipment. And the line card having a stacking port at the main equipment of the system executes the following steps: receiving a message sent from a line card having a stacking port at the equipment in the stacking system; according to a virtual destination address carried in the received message and a corresponding relation between a virtual destination address stored locally and the line card of the main equipment, determining a line card corresponding to the virtual destination address carried by the message; and sending the message to the determined line card, indicating the determined line card to carry out processing on the message and determining whether to send the message to a main processing unit of the main equipment for processing according to the processing result. According to the invention, parts of messages that are intended to be sent a CPU of a line card having a stacking port at main equipment in a stacking system for processing can be distributed to CPUs of other line cards of the main equipment for processing, thereby reducing CPU loads of the stacked line cards and improving the message processing efficiency.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a message processing method, a line card and switching equipment. Background technique [0002] A stacking system refers to more than one switching device connected through their respective stacking ports (ie, stacking ports) to form a "logical device", that is, to operate as a logical switching entity, so that users pass through this " "Logical Device" to manage all the switching devices in the "Logical Device". [0003] Such as figure 1 As shown, it is a stacking system including a switching device 11, a switching device 12 and a switching device 13. In the stacking system, the switching device 11 can be a master device, and other switching devices can be slave devices. The switching devices in the stacking system All can include main management board 1, management board 2, line card 1, line card 2, line card 3, line card 4, line card 5, and line card 6. To facilitate t...
