Problems solved by technology

[0021] It can be seen from the above process that because the FDB of the line card is small, address learning will stop when the FDB of the line card is full, and the number of destination MAC addresses that can be found in the FDB of the line card is also very limited. Packets that cannot be found in the FDB of the line card will be flooded, wasting port bandwidth, but the large-capacity FDB of the management board cannot be fully utilized

Abstract

The invention provides a method, a device, a line card and a management unit for message processing. The method comprises the following steps that: a receiving port of the line card receives a data message; and an FDB of the line card is searched according to a source MAC address of the data message and FDB list items of the line card and the management unit are updated according to the result of the search. Through the update of the FDB list items of the line card and the management unit on the line card, the method enables the FDB of the management unit to continue to perform list item update when the port state of the receiving port of the line card is learning, fully utilizes the large capacity FDB of the management unit, and facilitates the list item update of the FDB of the management unit.

Description

technical field [0001] The invention relates to a message processing method, device, line card and management board, belonging to the technical field of data communication. Background technique [0002] Chassis-type switching equipment is generally composed of chassis, backplane, management board, line card, power supply, fan and other modules. Each module is relatively independent and can be upgraded independently. This kind of equipment has good scalability, stability, etc. Lots of advantages. In this chassis structure, the line card and the management board are connected through the backplane, and the forwarding of data packets is provided through the cooperation of the line card and the management board. [0003] The management board is the control center and data forwarding center of the entire chassis-type switching device. Users can manage the entire chassis-type switching device system through the management board. A management board can connect multiple line cards...
