Embodiment Construction

[0058] The technical scheme of the present invention mainly uses the service board in the device to determine whether it needs to learn the MAC address of the currently received message, and after learning the MAC address, notify other service boards in the device to learn the MAC address currently learned by itself Address, thus freeing the main control board from the learning of controlling MAC addresses, thereby improving the efficiency of MAC address learning. Here, the described device may be a network processing device or a processing system including multiple service boards.

[0059] See figure 2 , figure 2 It is an exemplary flowchart of the method of the present invention. Specifically, in step 201, the service board receives a message and determines that it needs to learn the MAC address of the media access control of the currently received message, and then learns the MAC address of the currently received message. In step 202, the service board notifies other servic...

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 media access control (MAC) address, and a service board. Background technique [0002] In network processing equipment, message forwarding is an extremely important part. The realization of message forwarding mainly relies on the learning of MAC addresses. See figure 1 , figure 1 It is a structural diagram of a network processing device that uses MAC address centralized learning in the prior art. The network processing equipment includes a main control board and one or more service boards. Among them, the service board includes a port for receiving messages and a forwarding table used by the service board to forward messages. After the service board receives a 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, the VLAN i...
