Embodiment Construction

[0057] The technical scheme of the present invention mainly determines whether the service board in the device needs to learn the MAC address of the currently received message, and after learning the MAC address, notifies other service boards in the device to learn the MAC address currently learned by itself. address, so that the main control board is freed from controlling the learning of the MAC address, thereby improving the efficiency of MAC address learning. Here, the described apparatus may be a network processing device, or a processing system including multiple service boards.

[0058] Referring to Fig. 2, Fig. 2 is an exemplary flow chart of the method of the present invention. It specifically includes: in step 201, when the service board receives the message and determines that it needs to learn the MAC address of the currently received message, it learns the MAC address of the currently received message. In step 202, the service board notifies other service boards ...

Abstract

The method comprises: after receiving a message, when service board determines to learn the media access control (MAC) address of currently-received message, it learns the MAC address of currently-received message, and informs other devices in the apparatus where said service board is located to learn the MAC address of the currently-received message; when service boards receiving said notice determines to learn the MAC address of current message, it learns the MAC address of the current message. The invention also provides an apparatus for learning the MAC address.

Description

technical field [0001] The invention relates to data communication technology, in particular to a method and device for learning a medium access control (MAC) address, and a service board. Background technique [0002] In network processing equipment, packet forwarding is an extremely important link. The realization of packet forwarding mainly depends on the learning of MAC addresses. Referring to FIG. 1 , FIG. 1 is a structural diagram of a network processing device adopting MAC address centralized learning in the prior art. The network processing device includes a main control board and one or more service boards. Wherein, the service board includes a port for receiving messages, and a forwarding table used for forwarding messages by the service board. After the service board receives the message from the port, assuming that the received message here is a message from a virtual local area network (VLAN), the service board obtains the source MAC address of the message, t...
