Ethereum switch

1.

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

extended data

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

2. The Ge port is a Gigabit Ethernet port, and the ETH port is a fast Ethernet port, that is, a 100M Ethernet port.

Differences:

1. Different link sources

eth trunk: generally refers to the link aggregation of the same device. A switch binds multiple interfaces to form an eth trunk interface, so as to achieve the purpose of increasing bandwidth and improving reliability

e-trunk (enhanced trunk): generally refers to cross device link aggregation, which is a mechanism to realize cross device link aggregation. Based on LACP (single device link aggregation standard), it is extended to realize link aggregation among multiple devices. Thus, the link reliability is improved from the board level to the device level

2. Different advantages

eth trunk: load sharing can be realized through trunk interface. In an eth trunk interface, traffic load sharing can be realized. When the physical link connected by a member interface fails, the traffic will switch to other available links, so as to improve the reliability of the whole trunk link. The total bandwidth of trunk interface is the sum of the bandwidth of each member interface

e-trunk (enhanced trunk): it is mainly used for the link protection between CE and PE and the protection of PE equipment node failure when CE al homing access VPLS, Vll and PWE3 networks. Before e-trunk is used, CE can only return to one pe device through eth trunk link

If eth trunk fails or PE equipment fails, CE will not be able to continue to communicate with PE equipment. After using e-trunk, CE can be returned to PE, so as to realize the protection between devices

extended data

port aggregation is the aggregation of multiple ports to form a aggregation group, so as to realize the load sharing among the member ports in the aggregation group, and also provide higher connection reliability. Both e-trunk and eth trunk are link aggregation technologies

in some three-tier data center networks, the core layer is composed of two ce12800, and two 10GE links are aggregated between the two devices, so as to ensure the high reliability of the links. The convergence layer uses ce12800 switch stack to achieve rendant backup, and the stack is connected with upstream and downstream devices through cross frame eth trunk

at the same time, through the traffic local priority forwarding function of eth trunk, the bandwidth load of inter frame link is reced. The aggregation layer creates VRF to isolate service network segment route and public network route, and deploys firewall by side. Two firewalls carry out hot backup to ensure high reliability

5. Ethiopia is located in the northeast of Africa, on the southwest coast of the Red Sea, bordering on Djibouti and Somalia in the East, Sudan in the north and West, and Kenya in the south, covering an area of over 1103600 square kilometers. The coastline of Ethiopia is 1013km long. The territory is mainly mountainous plateau, most of which belong to the Ethiopian plateau. The central and western regions are the main part of the plateau, accounting for 2 / 3 of the whole territory, with an average altitude of 2500-3000m; African roof & quot; It's called "the best of the best"< At the same time, ETH is the country code of the Federal Democratic Republic of Ethiopia in FIFA.

6. Eth refers to Ethernet, 0 / 0 refers to port 0 of board 0, which is the first port of the first version card. In general, eth0 / 0 refers to the number of that port
you said 192.168.2.2 refers to the IP address of that port. The port also has an address. Just like your host, it also needs an address.

7. Ethernet generally refers to the 10m port on the router, and its full name is interface Ethernet. The other is the 100m port, which is called interface FastEthernet. This is the fast Ethernet port. If it is the specific port, it depends on the card of your equipment. Generally, the low-end old equipment is the 10m port

8.

The ETH of Huawei 5700 switch can be used as the management port. The switch operating system is lost, but I can upload the operating system files through the ETH port, which is similar to the function of the console port

Huawei switch is developed from network bridge and belongs to the second layer of OSI, namely data link layer equipment. It addresses according to MAC address and selects route through station table. The establishment and maintenance of station table is automatically carried out by Cisco Cisco switch

Huawei has set up a number of research institutes in the United States, Germany, Sweden, Russia, India, Beijing, Shanghai and Nanjing of China, and nearly half of its employees are engaged in the research and development of procts and solutions

Huawei is a leading telecom solution provider in the world. We have dedicated staff and strong R & D capabilities to quickly respond to customer needs, provide end-to-end customized procts, solutions and services, and spare no effort to help customers succeed in business. Through our joint efforts, we constantly enrich people's communication and life

Huawei procts and solutions cover mobile (LTE / HSPA / WCDMA / edge / GPRS / GSM, CDMA2000 1xEV-DO / CDMA2000 1X, TD-SCDMA and WiMAX)

core network (IMS, mobile softswitch, NGN), network (FTTx, xDSL, optical network, router and LAN switch), telecom value-added services (in, mobile data service, boss) and terminal (UMTS / CDMA)< br />

9. Huawei's ar series routers don't support layer-3 interface switching layer-2 interface, and S series switches don't support layer-2 interface switching layer-3 interface. So when you do a function, you should first read the proct manual clearly. Routing and switching technology is different from programming. It's not like writing a line of code to see the effect of a line of code. Routing and switching technology requires you to learn the theory clearly, To do configuration again is like a fish in water, otherwise it is called layman.

10. VLAN switches are not correct.
