Embodiment Construction

[0019] The general inventive concept of the present invention is to add the MAC address table of sub-processing unit according to distributed switch VLAN (Virtual Local Area Network, virtual local area network) member on each sub-exchange processing unit, to more effectively and fully utilize Ethernet Network switches have limited chip MAC address table space.

[0020] The processing method of adding MAC addresses according to VLANs in the present invention will be described below in conjunction with the accompanying drawings.

[0021] The method for effectively utilizing the MAC address table space in this embodiment includes the following steps:

[0022] In the first step, after a sub-exchange processing unit learns a certain MAC address, it generates a MAC address entry, adds it to the MAC address table of the unit, and notifies the main control processing unit at the same time;

[0023] In the second step, the main control processing unit notifies other sub-processing uni...

Abstract

A method of utilizing the ethernet network exchanger MAC address table space. The exchanger comprises a main control exchanging and processing unit and a plurality of sub-exchanging and processing units, the method comprises the following steps: a sub-exchanging and processing unit learns an MAC address, generates an MAC address item containing the virtual local area network VLAN corresponding to the MAC address and the port, and adds to the chip MAC address table of the processing unit; the sub-exchanging and processing unit informs the MAC address item to the main exchanging and processing unit, and the main exchanging and processing unit informs other sub-exchanging and processing units; the other sub-exchanging and processing units judges whether the processing unit has a VLAN membership port in the MAC address item, if the processing unit has, the MAC address item is added to the chip MAC address table of the processing unit, and if the processing unit doesn't have, the MAC address item isn't added. The present invention can effectively utilize the chip MAC address table space of the ethernet network exchanger.

Description

technical field [0001] The invention relates to the Ethernet communication technology, more specifically, a processing method for realizing the use of the limited chip MAC (Media Access Control) address table of the switch on the Ethernet switch. Background technique [0002] With the rapid development of the Internet, the Ethernet network has gradually become an indispensable tool in people's daily work and life, so the demand and processing capacity of the Ethernet switch are also increasing. As we all know, Ethernet switch is still a high-tech product with high cost. So, how can we maximize the data exchange capability of Ethernet switches at a certain cost? [0003] At present, the Layer 2 switching of the Ethernet switch is realized by the MAC address (the MAC address is the address used on the media access layer, also called the physical address) forwarding table. After the switch receives a data frame, it first learns the source MAC address of the data frame and the...
