Problems solved by technology

[0003] However, in the current switching equipment, there is no support for N:1VLAN translation for the switching equipment. This is mainly because the switching chips used by some switching equipment are proposed before the N:1VLAN model; :1 The implementation of VLAN gives a specific description
On the other hand, the realization of N:1VLAN translation is also related to the actual business planning, and the switch chip cannot implement a universal N:1VLAN translation method to meet the realization requirements of various N:1VLAN models

Embodiment Construction

[0033] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] figure 2 It is a schematic diagram of the switching equipment of the present invention, such as figure 2 As shown, the switching device of the present invention includes a receiving module, a parsing module, a translation module and a configuration module, wherein,

[0035] The receiving module is configured to forward the received uplink messages of N predetermined protocols to the parsing module, and forward the received downlink messages to the translation module, wherein N is greater than or equal to 1;

[0036] The parsing module is configured to parse out the source MAC address and VLAN of the uplink message, output the source MAC address of the uplink message to the configuration module, and output the VLAN of the uplink message to the translation module;

[0037] The transl...

Abstract

The invention provides a method and exchange equipment for realizing N:1 VLAN translation. The method comprises the following steps: receiving N uplink messages of a preset protocol, wherein N is more than or equal to 1; respectively analyzing the source multimedia access control (MAC) address and a virtual local area network (VLAN) of the uplink message, translating the VLAN of the uplink message into a designated VLAN; configuring the downlink VLAN translation strategy according to the source MAC address of the uplink message; and translating the VLAN of the downlink message to a VLAN corresponding to the source MAC address according to the corresponding downlink VLAN translation strategy if the received VLAN of the downlink message is the designated VLAN. According to the method, VLAN of a plurality of VLAN messages received from a certain port can be translated to the same VLAN, VLAN planning for a superior network can be simplified, and the network planning and management cost can be reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and switching equipment for realizing VLAN translation. Background technique [0002] At present, with the popularization of network applications and the increase in the complexity of network planning, the diversity of VLAN (Virtual Local Area Network, Virtual Local Area Network) models on switching devices has been brought about, which requires the current switching chips to be well adapted to this change. Among many current VLAN models, VLAN translation is more and more commonly used in various business scenarios. There is a special VLAN model in VLAN translation, that is, the N:1VLAN model. At present, the N:1 VLAN model has received more and more attention and recognition in the industry. The reason is that this VLAN model can simplify the VLAN planning of the upper-layer network and reduce network planning and management costs. figure 1 The model diagram of N:1VLAN is gi...
