What Is Ethernet Quality Tester?

As the name suggests, an Ethernet Quality Tester is a switch that transmits data over Ethernet. It is structured in such a way that each port is directly connected to the device and operates in full-duplex mode. The switch can connect multiple pairs of ports at the same time, so that each pair of hosts communicating with each other can transmit data independently and without conflict.

The Pocket Ethernet Tester we use are usually connected to devices such as NVR (Network DVR), DVR (DVR), IPC (Network Camera), router, PC, server and other devices. These connected devices will each have their own MAC address, and their devices must have an IP address specific to it.

The Ethernet switch works in the second layer of the OSI network reference model (that is, the data link layer), and is a network device based on MAC (Media Access Control) address recognition and completing Ethernet data frame forwarding.

The Ethernet switch accepts the data frame sent by the network on the port, identifies the data, and then forwards the data frame from the corresponding port, thereby implementing data exchange.
