Problems solved by technology

[0006] The present invention provides a MAC address learning control method and a forwarding device to at least solve the problem that the forwarding device only controls the learning of the MAC address in a fixed way during the message forwarding process, and the MAC address learning method is single, which limits the learning of the MAC address. The problem

example 1

[0054] like figure 2 As shown, this embodiment includes step S202 to step S224:

[0055] Step S202, obtain message information, that is, the system obtains the incoming port information, source MAC address information, and destination MAC address information of the message, and judges whether the MAC address tag information is a broadcast (multicast) attribute or a unicast attribute according to the destination MAC address .

[0056] Step S204, searching the MAC address forwarding table according to the port information and the source MAC address information, and judging whether there is a corresponding forwarding entry. If the corresponding forwarding entry can be found, go to step S206; otherwise, go to step S208.

[0057] Step S206, update the MAC address forwarding table entry corresponding to the source MAC and port information, and proceed to step S220. During the execution of this step, what is updated may be the aging time, the usage of forwarding entries, or both....

[0071] like image 3 As shown, it is a flowchart of a method for controlling MAC address learning, which includes steps S302 to S326:

[0072] Step S302, obtain message information, mainly is to obtain the ingress port information of message, the source MAC address information of message and the destination MAC address information of message, and judge that MAC address mark information is broadcast (multicast) according to destination MAC address ) attribute or unicast attribute.

[0073] Step S304, searching the corresponding MAC address forwarding table according to the acquired source MAC address information and ingress port information, and judging whether it can be found. If it can be found, it means that it has been created, go to step S306, otherwise go to step S308.

[0074] Step S306, update the aging time of the entry corresponding to the MAC address forwarding table, and proceed to step S320.

[0075] Step S308, judging whether the current MAC address capacity is...

Abstract

The invention discloses a control method of MAC address study and forwarding equipment. The method comprises the steps of receiving messages, and according to the attribute information of the messages, judging whether to conduct MAC address study according to the messages , wherein the attribute information comprises one of unicast, multicast and broadcast. By the adoption of the control method of the MAC address study and the forwarding equipment, the problems that when a fixed mode is used for controlling MAC address study, the MAC address study is single in mode, and the MAC address study is restricted are solved. The control method of the MAC address study can be controlled according to different requirements of the attribute information, can avoid impact of a large amount of broadcast or multicast messages existing in a network on system MAC address capacity, enables a system to study useful MAC address on the condition that capacity is limited, and improves system performance.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a control method and a forwarding device for learning a Media Access Control (MAC) address. Background technique [0002] With the development of the network, the IP network has become an indispensable communication tool in people's daily life. In the forwarding process of network data, the MAC address learning function is a necessary function for each network device. MAC address information for packet forwarding. [0003] However, in the actual network environment, there will be a large number of broadcast packets and multicast packets. Many of these packets are miscellaneous packets. However, network devices do not need to care about the MAC address information of miscellaneous packets. In the current address In the learning solution, the network devices all learn the MAC address information of these packets, and the MAC address information occupies the limited address capac...
