How does china Ethernet Switch Telecom/Datacom Systems work


Every China Ethernet Switch Telecom/Datacom Systems has a hard-coded physical address called a MAC address, which is used by the connecting switch to identify the device.

When a China Ethernet Switch Telecom/Datacom Systems receives an Ethernet packet, it stores the MAC address of the sending device and the port it is connected to in a locally kept table called a MAC address table. The switch process then checks the MAC address table to see if the destination MAC address is connected to the same switch. If so, the switch forwards the packet to the known destination port. If not, the switch broadcasts the packet to all ports and waits for a response.

If China Ethernet Switch Telecom/Datacom Systems is directly connected to the target device, the device accepts the packet, responds, and the transmission is complete. If the device is connected to another switch, the next switch will repeat the lookup and forwarding process until the frame reaches the intended destination.
