Problems solved by technology

Usually, the MAC address drift is controlled by the priority of the port. This method has the advantage of flexible control, but it is cumbersome in engineering debugging and application, and needs to traverse and modify the port priority information.

Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0032] figure 1 It is a flowchart of a method for controlling MAC address drifting according to an embodiment of the present invention, such as figure 1 As shown, the method of the present embodiment includes:

[0033] Step 11, after receiving the message, query the forwarding instance information corresponding to the message, and obtain the MAC address drifting enable flag;

[0034] Step 12: Query the MAC address table, if the port number of the MAC address entry is inconsistent with the port number of the incoming packet, control the MAC address flapping according to the ...

Abstract

Disclosed is a controlling method and controlling device for MAC address drifting. The method comprises: obtaining an MAC address drifting enabling flag according to forwarding instance information corresponding to a received message; controlling the MAC address drifting according to the MAC address drifting enabling flag when it is determined that the port number of the MAC address item in the MAC address table is inconsistent with the input port number of a received message. With the new MAC address drifting enabling flag, the embodiments of the present invention provide a global control on the basis of the port priorities simply by modifying the global configuration of instances, i.e., the controlling of MAC address drifting is simply realized, while the maintenance and utilization of engineering are more convenient.

Description

technical field [0001] The present invention relates to the technical field of two-layer forwarding of communication equipment in the field of communication, in particular to a method, device and network equipment for controlling MAC (Media Access Control, Media Access Control) address drift. Background technique [0002] Due to its simplicity, convenience, and high efficiency, Ethernet has become the most commonly used technology in local area network networking and broadband access networks. However, due to its broadcast characteristics, Ethernet is extremely fragile. [0003] Ethernet loops are due to irregular network connections, line collisions, etc., resulting in loops in the data forwarding path of the entire network. The resulting hazards mainly include broadcast storms, MAC address drift, and forwarding table confusion, etc. blocking and interruption. In addition to network connection problems, frequent MAC address drift caused by network attacks is also an import...
