The con port is the console interface, which is directly connected to the serial port of the computer by using the console cable. The router is configured locally by using the terminal emulator (generally using the "super terminal" of windows)
eth port is Ethernet interface, and Ethernet interface is the port of network data connection, which connects different computer devices together. The basic elements of Ethernet equipment networking include switch, router, hub, optical fiber and common network cable, Ethernet protocol and communication rules

switches that can be used for network management generally have a "console" port, which is specially used for the configuration and management of switches. Connecting and configuring the switch through the console port is a necessary step to configure and manage the switch
because other configuration methods often need the help of IP address, domain name or device name, and it is obviously impossible for newly purchased switches to have these parameters built-in, so the console port is the most common and basic switch management and configuration port
console ports of different types of switches are located in different positions, some on the front panel and some on the back panel. Generally, molar switches are mostly located on the front panel, while fixed configuration switches are mostly located on the back panel. On the top or side of the port, there will be a sign similar to "console"
Ethernet interface types: SC optical fiber interface, RJ-45 interface, FDDI interface, AUI interface, BNC interface, console interface
After reading the answers of other respondents, I really want to laugh. It's not terrible to pretend that I don't understand. What's terrible is to answer blindly. There's something wrong with this question. The burst of 5.7 billion yuan has nothing to do with a drop of 10 cents. It can even be said that its disappearance is e to the sharp rise. So where is the decline? If bitcoin really falls, it will not be 5.7 billion capital washed away, it will be tens of billions, hundreds of billions of capital evaporated, those who talk about trends and development, please study the capital and stock market well, and by the way, please search for the meaning of the word "burst", no culture is too terrible
in addition, I would like to make a digression. Recently, a hot topic is fund. In 2021, the annual meeting is more or less a national fund. In 2020, the fund manager is still a good active fund. Even if the position is not changed, the annual yield will reach at least 40%, but this does not mean that this year is still OK, It's not that everyone can make money playing with funds. it's similar to the nature of stocks. Index funds, stock funds and even active funds are risky. I think many people say that they should get on the bus quickly. They are really worried about your funds of course, 2021 may be a bull market. It is estimated that the whole network has spread, many people are rubbing their hands to make a lot of money, but I can't do much. I just advise you not to go with the flow too much, don't be greedy, and don't think you are. That's all. Good luck

It is also a new political and economic center and commercial and cultural center of Hefei, the provincial capital, integrating the functions of administrative office, culture, ecation and sports, Finance and trade, tourism and vacation, residence and leisure
The common information of Hefei administrative district is as follows:1. Area: About 6km southwest of the old city center
2. Area code: (+ 86) 0551
3. Administrative division code: 340100
4. License plate code: Wan a
extended information:
located in the main direction and heart of Hefei urban development sector, the new administrative and cultural zone is the only way to connect the main urban area, economic and Technological Development zone and university town. It is 20 minutes' drive from Hefei railway station, close to Hefei West Railway Station, and adjacent to Hefei Nanjing, Hefei Xuzhou, Hefei Wuhu expressways, It's only 10 minutes' drive from Hefei Luogang airport, and the airport and station are within the "living circle" of 20 minutes. It is not only the throat of the main urban area's westward and southward expansion, but also a beautiful window to reflect the image of modern Hefei City in the demonstration area of Wanjiang city belt's undertaking instrial transfer
China's postal code adopts a four level six digit structure. The first two digits indicate the province (municipality directly under the central government or autonomous region); The first three digits indicate the postal area; The first four digits represent counties (cities); The last two digits indicate the delivery office. Postcode is to realize the implementation of automatic mail sorting scheme, because the computer can not recognize Chinese, but can recognize numbers. Code each area, can quickly use the computer sorting, to write the more detailed the better

eth trunk interface is a kind of interface that can be created dynamically. This type of interface can be bound with several physical Ethernet interfaces as a logical interface. The Ethernet interface added to the ETH trunk interface is called the member interface. Users only need to configure the ETH trunk interface, and these configurations will eventually be mapped to the member interface. The ETH trunk interface can be divided into routing mode and switching mode. The routing mode Ethernet trunk interface is similar to the routing mode Ethernet interface, which can configure IP address, run various routing protocols, MPLS VPN and other services; The ETH trunk interface of switching mode is similar to Ethernet interface of switching mode, which can join VLAN, run STP and other protocols
the application features of eth trunk interface include expanding interface bandwidth, increasing link reliability and load sharing of traffic
it is suggested that you can consult PC networking professionals for relevant questions, and the following pictures are for reference:
