Detection method, device and system of Ethernet switch internet access

Abstract

The invention discloses a detection method, device and system of an Ethernet switch internet access. The method comprises the following steps: sending a constructed multicast packet to a predeterminedinternet access of a switch through a pre-created first virtual internet access, wherein each of N internet accesses except the predetermined internet access is provided with a self-loop head, and isconfigured with a first virtual local area network identifier vlan id and a second vlan id, all internet accesses of the switch form a loop; receiving the multicast packet returned by the switch through the predetermined internet access through the pre-created second virtual internet access, wherein the multicast packet is transmitted back to the predetermined internet access through N internet accesses from the predetermined internet access; and detecting the internet access of the switch according to the received multicast packet. The problem that multiple internet accesses cannot be simultaneously tested since the traditional internet access testing method needs to externally connect testing equipment is solved; by using the vlan technology and the self-loop head, the testing process is simplified, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to the field of communication equipment, in particular to a method, device and system for detecting a network port of an Ethernet switch. Background technique [0002] With the development of network and communication technology, there are more and more devices with Ethernet ports. For manufacturers of network devices, how to quickly detect the quality of network ports to ensure the quality of network ports is particularly important. Commonly used network port detection methods require an ordinary PC (personal compute) or some special equipment to be tested by connecting the device under test. For the device under test with only one network port, this method is simple and convenient, and the operation is not troublesome. However, for a switch with more than one network port, testing one network port after another will lead to low efficiency; at the same time, the use of special instruments for testing increases the test cost and ...
