Switch spanning tree protocol anti-loop stability test method and tool

Abstract

The invention discloses a switch spanning tree protocol anti-loop stability test method and a switch spanning tree protocol anti-loop stability test tool. A stability test is carried out on three loopscenes, a host is provided and is provided with a first network card and a second network card, and a serial port line is connected with the host and the tested switch A; an automation program is installed in the host, a tester starts to operate the automation program to form an operation interface and sets parameters, the automation program sends an instruction to a serial port tool CRT of the host, and the tested switch A and a tested switch B form a spanning tree protocol; the automatic program collects the records of the serial port tool CRT and stores the files, and the storage paths ofthe spanning tree message are correspondingly P1, P2 and P3, so that the stability tests of the first loop scene, the second loop scene and the third loop scene are finished, the operation is simple,and the efficiency is high.

Description

[0001] 【Technical field】 [0002] The invention relates to a method and a tool for testing the anti-loop stability of a spanning tree protocol of an exchange, in particular to a method and a tool for testing the anti-loop stability of an exchange spanning tree protocol with simple operation and high efficiency. [0003] 【Background technique】 [0004] The spanning tree is the main function of the switch, which plays a role in preventing loops. The switch must ensure that in the actual network environment, if a loop occurs, it will not affect the normal business communication. Testers need to simulate real network traffic scenarios in the laboratory Next, verify the anti-loop stability of the switch to avoid communication problems in the actual application of the final product. [0005] At present, there are two test methods on the market: the first is to purchase expensive test equipment to simulate the switch for coordination verification, but the cost of the test equipment is...

Problems solved by technology

[0005] At present, there are two test methods on the market: the first is to purchase expensive test equipment to simulate the switch for coordination verification, but the cost of the test equipment is very high, and one port can only simulate one switch, and multiple switches need to be occupied at the same time Port, also need to buy Lincense

The second is to test as many switches as possible in the laboratory and use real switches for testing, but this requires a lot of resources, and the networking is very complicated. In many cases, such experimental conditions are not available, so it is practical Low sex
