What is the difference between the G port, f port

The meaning of serial interface is also called high-speed asynchronous serial port. It is mainly used to connect the V.35 cable of the WAN. In other words, it is used when connecting the router and the router. You can use commands to set the bandwidth, which is generally around 10m and 8m.

It is an Ethernet interface, called Ethernet interface. It is mainly used to connect Ethernet (local area network). It can also be connected with ordinary twisted pair. The default speed is 10Mbps. Now this interface has been eliminated in new equipment. In addition, a necessary interface on the router is the console interface, called the control interface, which is used to debug the router. Some routers also have aux interfaces, which are also control interfaces; There is also a g-port, which is a Gigabit Ethernet interface used to connect Ethernet.

Switch optical fiber finit

It is a FastEthernet interface, a fast Ethernet port, also known as a 100m port. It is mainly used to connect Ethernet (local area network). In other words, it is used to connect switches or computers. It can be connected with ordinary twisted pair. The default speed is 100Mbps. The command speed limit can be used, but it cannot exceed 100Mbps.

G port means gigabitethernet, which means Gigabit port. Gigabit only means that it is a Gigabit port. The display is the same whether it is an optical port or an electrical port. If you want to see it in detail, you can view it in display int.

The gigabitethernet can be either an optical port or an electrical port, depending on the device parameters. Ethernet is an Ethernet port, and gigabitethernet is a Gigabit Ethernet port. Both are defined by IEEE 802.3-2005 standard, and can use network cable or optical fiber.
