Problems solved by technology

[0012] 1. In order to set a static Mac, you must first manually obtain the gateway Mac address, and then configure network devices such as switches one by one, which is troublesome;
[0013] 2. Due to migration and other reasons, network devices such as the gateway connected to the switch may change, which requires manual adjustment in the network device; therefore, in actual networking applications, there will be a lot of static Mac configuration and deletion work ;
[0014] 3. The physical distance between the gateway and the gateway, as well as the gateway and the switch may be far apart, so manual configuration is very inconvenient

Embodiment Construction

[0031] In order to overcome the complex operational problems existing in the existing gateway Mac static binding technology, the present invention provides a technical solution for realizing gateway Mac binding, which will be described in detail below.

[0032] At first, the present invention provides a kind of method that realizes gateway Mac binding, considers based on the following two aspects: on the one hand, because network equipment such as two / three-layer switches and routers are all maintained by the VLAN network maintainer, it is impossible Actively initiate network attacks, so the information it sends is reliable; on the other hand, the legal gateway Mac address transmission path is from the network device to the terminal. Therefore, when only the binding authority of the connection port between network devices is opened, It provides a precondition to ensure that the switch will not be confused by the fake message sent by the Host. Therefore, the correct binding betw...

Abstract

The disclosed gateway Mac bonding method comprises: when network topology changes, activating the bonding right of device ports connected with each other; when receiving a first / second appointed-format message, detecting whether its port is the activated port; yes to automatic bonding / debonding the relative relation between the port and the gateway Mac address. This invention avoids pretended gateway Mac attack, and reduces right bonding complexity.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for realizing gateway Mac binding, a component, a gateway and a layer-2 switch. Background technique [0002] With the popularization and development of network communication, the interaction and sharing of information through the network has become the basic means of daily communication for individuals, enterprises and even large organizations. Therefore, as a basic network device, whether the switch can realize the correct forwarding of network packets is directly related to the normal operation of the network, and is closely related to the work, life and entertainment of users. [0003] As far as the network packet forwarding process of a virtual local area network (Virtual Local Area Network, VLAN for short) is concerned, whether it is a layer 2 switch or a layer 3 switch, the forwarding of the message data packet will be carried out according to the Ma...
