What is the difference between G port, F port, E port and S port on the switch device?

What interfaces does a switch have? What is the role of each interface, in this issue we will take a look.

S-port

The meaning of the Serial interface, also known as high-speed asynchronous serial port, is mainly connected to the wide area network V.35 cable, to put it bluntly, it is used when the router and the router are connected, and the bandwidth can be set with commands, generally around 10M and 8M.

E mouth

Is the Ethernet interface, called Ethernet interface, is also the main connection to Ethernet (landown network), but also with ordinary twisted pair can be connected, the rate default is 10Mbps, now the new type of equipment has been eliminated this interface. In addition, there is an indispensable interface on the router is the Console port, called the control port, which is used to debug the router. Some routers also have AUX interfaces, which are also control interfaces; and G-ports, which are Gigabit Ethernet interfaces, are used to connect Ethernet.

F port

It is the FastEthernet interface, fast Ethernet port, also known as 100 Mega ports. Main connection to Ethernet (landown network) used, to put it bluntly, is to connect the switch or computer, with ordinary twisted pair can be connected, the rate default is 100Mbps, you can use the command speed limit, but it is impossible to exceed 100Mbps.

G-port

G-mouth is the meaning of Gigabitethernet, which is a gigabit mouth. Gigabit only means that it is a gigabit mouth, whether it is a light port or an electrical port display is the same, if you want to see in detail, you can display int to view.

GigabitEthernet can be a light port or an electrical port, depending on the equipment parameters. Ethernet is an Ethernet port and Gigabit Ethernet is a Gigabit Ethernet port, both of which are defined by the IEEE 802.3-2005 standard and can be used for network cables or fiber optics.
