Serpentine-flow-based network port testing method

Abstract

The invention discloses a serpentine-flow-based network port testing method, which comprises the following steps of: judging whether a system is a single-chip forwarding system or a multi-chip forwarding system; setting serpentine flow rules according to a system type; setting a port loopback function by using a command line according to a chip register; performing networking according to a networking diagram; starting the flow test of a tester; and when the test is performed for a preset time, observing the packet loss condition of the test to finish the test. The network port testing method has the advantages of shortening the test period of high-density network equipment, lowering test cost, and the like.

Description

technical field [0001] The invention relates to a network port testing method based on serpentine flow. Background technique [0002] In communication equipment, the density of network ports is getting higher and higher, especially in high-density switches and routers, which brings great inconvenience to the flow test of network ports, increases in material costs and shortens the test cycle. extend. With the development of cloud computing, especially the accelerated construction of large-scale data centers, the demand for high-density network equipment has increased sharply. The current test methods for low-density network equipment have affected the test efficiency of high-density network equipment. [0003] For low-density network devices such as Figure 4 As shown, there are few network ports. The current test method is: from port 1 to port 12, test each port one by one, exchange traffic between two ports, and then test all ports in a traversal manner. [0004] For high...

Problems solved by technology

[0004] For high-density network equipment, such as Figure 5 As shown, the number of network ports is large, and the current test method is applied, the test cycle is greatly extended, and the test cost is greatly increased, which brings great challenges to the timely introduction of products to the market

When using the existing method of testing a large number of network ports one by one, it has the following disadvantages: the test cycle is long, the efficiency is low, and all network ports need to be traversed, which is only suitable for network devices with small port density. With the increase of device port density , the test cycle of this method will increase the cost; more manual participation, port traversal test, need to manually replace the network cable, optical module, optical fiber, etc., must have a special person in charge of the entire test process
