Local area network system, core layer switch, access layer switch and configuring method thereof

Abstract

The invention discloses a local area network system, a core layer switch, an access layer switch and a configuring method thereof. The method includes: sending a configuring command message to the access layer switch by the core layer switch in the local area network system; and realizing forwarding of a data packet by the access layer switch according to network configuring information indicatedin the configuring command message. By applying the method, configuring and management on the access layer switch can be facilitated, and later maintenance and network extension can be facilitated.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a local area network system, a core layer, an access layer switch and a configuration method thereof. Background technique [0002] Network switches are switches that transmit data based on Ethernet, and Ethernet technology has become the most important LAN networking technology today, so network switches have become the most popular switches. Ethernet switches used in local area networks can be used to connect terminal devices, such as PCs and network printers. The structure of the Ethernet switch is that each port is directly connected to the host, and generally works in full-duplex mode. The switch can connect many pairs of ports at the same time, so that each pair of hosts that communicate with each other can transmit data without conflict as if it is an exclusive communication medium. [0003] Local area network usually adopts the hierarchical model design of three-layer ...

Problems solved by technology

[0004] It is difficult to accurately manage the access layer switches of the traditional enterprise local area network. It is necessary to manage a large number of homogeneous access devices. It is necessary to remember the management address of each switch, different configurations and other information, which is very difficult to maintain.

In particular, in some large-scale local area networks, the access layer switches are of different brands and models, and the configuration methods are quite different. It is very difficult to maintain. At the same time, they cannot be replaced independently, and supporting equipment needs to be considered; and later configuration changes and expansion are also very difficult.
