Abstract

The invention provides a data transmission control method and device. The method comprises the steps of determining a forwarding VLAN of uplink data streams which are allowed to pass through by a target port when it is determined that the condition that the forwarding virtual local area network VLAN of the uplink data streams is different from an initial VLAN exists in the target port; closing a VLAN filtering detection function for the target port, wherein the function is in a chip corresponding to the target port and is started by default; and setting the target port to allow the uplink data streams of the forwarding VLAN to pass through and forbid the uplink data streams of other VLANs to pass through. Through application of the embodiment of the method and the device, filtering detection based on the forwarding VLAN can be realized, and the possibility of generating a loop is reduced.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data transmission control method and device. Background technique [0002] Port-based VLAN (Virtual Local Area Network, virtual local area network) division is the simplest and most effective VLAN division method. It defines VLAN members according to device ports. After adding a specified port to a specified VLAN, the port can forward packets of the VLAN. [0003] In order to implement port-based VLAN division, the chip needs to perform VLAN filtering inspection on the data flow received by the port, as follows: [0004] Ports that need to communicate are added to the same VLAN; ports that need to be isolated are added to different VLANs; [0005] The chip performs a VLAN filtering check on the upstream data flow, and only the ports that have been added to a certain VLAN allow the upstream data flow of the VLAN to pass through; otherwise, data flow filtering is ...
