Problems solved by technology

[0006] The test intensity is too low, the flow of test packets is not large, the test intensity is small, and the connectivity problem of the switch port cannot be fully tested, and some switch port connectivity problems can only be exposed when a large amount of traffic is forwarded.

Embodiment Construction

[0034] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail again

[0035] The technical scheme adopted by the present invention is based on the test of the connectivity of the port of the switch under the condition of the broadcast storm of the first test message. The basic idea is: connect every two tested ports of the switch as a group using physical lines, use the first test message on the test port to generate a broadcast storm, and then generate the first test message broadcast storm on the port , using the second test packet to test the connectivity of the port.

Abstract

The invention discloses a method for testing port connectivity of a switch. The method includes connecting each two tested port in one group by physical circuits; configuring forwarding profile for the tested port; forwarding to other ports in the switch in case of receiving a first testing message; reporting to a control surface in case of receiving a second testing message; constructing the first testing message to be forwarded to the tested port by the control surface; constructing the second testing message with priority level higher than the first testing message to be transmitted to the tested port by the control surface after the tested port generates broadcast storm; receiving the second testing message by a second tested port connected with the tested port physically, then transmitting the second testing message to the second tested port, and finally, receiving the second testing message from a testing port; judging connectivity of the two tested ports connected physically by comparing consistency of receiving and transmitting the second testing message. By the method for testing port connectivity of the switch, testing intensity can be improved, and connectivity testing of the ports of the switch can be realized more sufficiently.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a test method for the connectivity of a switch port. Background technique [0002] Switches are one of the most common networking devices used to build communication networks. All switches require production testing before they leave the factory. It mainly involves the test of switch port connectivity. The test of the connectivity of the switch port refers to the test of the ability of the switch port to send and receive messages. If the port of the switch can receive and send messages correctly, the port is not faulty, otherwise the port is faulty. Currently, the test methods for port connectivity of switches mainly include forwarding test methods and loopback test methods, which are introduced one by one below. [0003] Existing technology 1. Forwarding test method: In the public documents of Chinese Patent Application Publication No. CN 101296131, Patent Appli...
