Method and device for testing network port traffic

Abstract

The embodiment of the present application discloses a method for testing network port traffic. The multiple ports of the network device under test are connected to the multiple ports of the network tester in one-to-one correspondence, and the multiple ports of the network device under test are connected according to the The preset sequence is connected sequentially, and the first port in the preset sequence is connected to the last port to form a full-port direct connection loopback topology. When testing, the network tester sends a test message to the second port of the network device under test through the first port; the first port is any port on the network tester, and the first port is connected to the second port correspondingly; the network tester The test message sent from the fourth port of the network device under test is received through the third port; the fourth port is connected with the second port inside the network device under test; the third port is correspondingly connected with the fourth port; the network tester is in the The third port analyzes the tested message to obtain the analysis result. Therefore, the faulty port can be quickly diagnosed and the performance of fault diagnosis can be improved.

Description

Technical field [0001] The present application relates to the field of network equipment testing, in particular to a network port traffic test method and apparatus. Background [0002] Network devices and components are physical entities connected to the network, such as computers, switches, routers, etc., and the port traffic of network devices has an important impact on the performance of network devices. [0003] The port traffic of the network device can be tested by the network tester, which is a common instrument in network communication, presenting several Ethernet ports to the user, and connecting with the network device under test through this port, so as to realize the test of the network device under test. [0004] At present, the snake-shaped self-ring topology flow test method is usually used, but this method cannot quickly diagnose the specific fault port, which is not conducive to the maintenance of the back end, that is, poor reliability, poor fault diagnosis per...

Problems solved by technology

[0004] At present, the serpentine self-loop topology flow test method is usually used, but this method cannot quickly diagnose the specific fault port, which is not conducive to the maintenance of the back end, that is, poor reliability, poor fault diagnosis performance, and heavy maintenance workload; in addition, this method Difficult to detect clock-related failures such as clock drift
