Method for port line-speed transmitting test data frame and Ethernet switchboard

Abstract

The invention provides a method for sending testing data frame in port line-speed by using the Ethernet switch, which comprises the steps that: establishing a virtual local area network (LAN) which contains one first class port and a plurality of second class ports, wherein, the virtual local area network tag of the virtual local area network is corresponding to the mark of the first class port in the virtual local area network; sending test data frame with the virtual local area network tag of the virtual local area network to one of second class ports; broadcasting and testing data frame by the second class ports which has received the test data frame in virtual local area network which is corresponding to the virtual local area network tag to form broadcast storm among a plurality of the second ports; retransmitting the received test data frame brought by broadcast storm to the equipment to be tested by the first class port. By adopting the technical proposal, the invention can send test data frame in the equipment port line-speed without network processor and FPGA, thereby, reducing the cost of research, development and production.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for transmitting a test data frame at a line speed of a port of an Ethernet switch and the Ethernet switch. Background technique [0002] With the development of the network, the output of network communication equipment is also increasing, and usually no matter in the R&D department or the production department, the number of dedicated testers is very tight. This is because although the special tester is powerful, it is expensive and the number of test ports provided is limited. To speed up the production and testing, a large number of special testers will increase the cost of the product. [0003] If the existing communication equipment products are temporarily transformed into testers, the products can be used to test the products as much as possible, which is very meaningful for the product inspection and testing of the production line. For example, the port of ...
