华为5700交换机eth接口做什么用的？怎么使用它？

一、Eth-Trunk接口概述

I. Overview of the Eth-Trunk interface

当前的一种局域网通讯方式，也同样是一种协议，也是互联网连接的一端口。其实每一个版本都会有着电缆的限度，在这一个范围内信号本身就可以正常的传播，而在超过这一个信号之后，根本就没有办法传播，为了能够允许建设更多的网络。

The current local area network (LAN) mode of communication is also a protocol and an interface to the Internet. In fact, each version has a cable limit, within which the signal itself can be transmitted normally, and beyond which there is no way to disseminate it, in order to allow more networks to be built.

所以本来就需要把多条电缆完全的连在在一起，因此交换机eth接口本身也就是一种能够接受并且放大的线缆，能够有效发放各种不一样的信号。

There is therefore a need to fully connect multiple cables, so the switch-eth interface itself is an acceptable and magnified cable capable of effectively delivering different signals.

ETH有专用的DMA控制器，它通过AHB主从接口与内核和存储器相连，AHB主接口用于控制数据传输，而AHB从接口用于访问"控制与状态寄存器"(CSR)空间。

ETH has a dedicated DMA controller, which links the AHB main from the interface to the kernel and , while the AHB main interface is used to control data transmission, while the AHB main interface is used from the interface to access &quat; the Control and Status Depositor &quat; (CSR) space.

在进行数据发送是，先将数据有存储器以DMA传输到发送TX FIFO进行缓冲，然后由MAC内核发送；接收数据时，RX FIFO先接收以太网数据帧，再由DMA传输至存储器。

When the data are sent, the data are transferred by a repository to DMA for buffering to send TX FIFO and then sent by the MAC kernel; when the data are received, RX FIFO receives the Ethernet , which is then transmitted by DMA to the repository.

二、Eth-Trunk接口概念

II. Eth-Trunk interface concept

Eth-Trunk接口的概念主要包括链路聚合模式、Eth-Trunk接口公有参数、静态LACP模式Eth-Trunk接口参数、Eth-Trunk接口成员口参数和静态LACP模式下Eth-Trunk接口成员口的状态。

The concept of the Eth-Trunk interface consists mainly of the chain polymer mode, the Eth-Trunk interface common parameters, the static LACP mode Eth-Trunk interface parameters, the mouth parameters of the Eth-Trunk interface members and the state of the mouth of the members of the Eth-Trunk interface under the static LACP mode.

三、如何使用ETH接口

III. How to use the ETH interface

eth 代表ethernet 以太网的意思eth0，eth1，eth2，代表网卡一，网卡二，网卡三。

Eth for Ethernet, Eth0, Eth1, Eth2, for Netcard I, Netcard II, Netcard III.

ifconfig配置网卡配置网卡的IP地址ifconfig eth0 192.168.0.1 netmask 255.255.255.0在eth0上配置上192.168.0.1 的IP地址及24位掩码。

ifconfig eth0192.168.0.1 netmask 255.255.255.5.0 on eth0 with IP addresses and 24 places

要在eth0上在配置一个192.168.1.1/24 的IP地址，用下面的命令ifconfig eth0：0 192.168.1.1 netmask 255.255.255.0这时再用ifconifg命令查看，就可以看到两个网卡的信息了，

If you want to configure an IP address on eth0 with an IP address in 192.68.1.1.24, you can see the information on the two webcards with the following command: 0192.168.1.1 netmask 255.255.255.0

Eth-Trunk配置逻辑

Eth-Trunk Configuration Logic

Eth-Trunk接口是一种捆绑技术，将多个以太网接口捆绑成一个逻辑接口，从而实现增加带宽、负载分担等功能，帮助提高网络的可靠性。

The Eth-Trunk interface is a bundled technology that binds multiple with the interface to a logical interface to achieve additional bandwidth, load-sharing and help improve network reliability.

当前，NE20E支持静态LACP模式Eth-Trunk、手工负载分担模式Eth-Trunk和手工1:1主备模式Eth-Trunk。无论Eth-Trunk处于什么模式，Eth-Trunk接口的配置逻辑如下：

Currently, NE20E supports static LACP models Eth-Trunk, manual load-sharing models Eth-Trunk and manual 1:1 Eth-Trunk. Whatever pattern Eth-Trunk is in, the configuration logic of the Eth-Trunk interface is as follows:

1、创建Eth-Trunk接口，并确定Eth-Trunk接口的链路聚合模式。

1. Create the Eth-Trunk interface and determine the mode of connection aggregation of the Eth-Trunk interface.

2、向Eth-Trunk接口中加入成员接口，使Eth-Trunk接口生效。

2. Add a member interface to the Eth-Trunk interface to give effect to the Eth-Trunk interface.

3、为了提高Eth-Trunk接口的可靠性，可通过调整Eth-Trunk接口的参数和成员口参数实现。

3. In order to improve the reliability of the Eth-Trunk interface, this can be achieved by adjusting the parameters and membership parameters of the Eth-Trunk interface.

4、（可选）现实组网中，Eth-Trunk接口经常和其他特性综合运用，以提高整网的可靠性。如：配置Eth-Trunk子接口支持VLAN间通信。

4. In the (optional) reality group network, the Eth-Trunk interface is frequently combined with other features to improve the reliability of the whole network. For example, configuration of the Eth-Trunk sub-intercom supports VLAN communications.

华为5700交换机eth可以作为管理口使用，交换机操作系统丢了 ，但是我可以通过eth口上传操作系统文件，跟console口的功能是类似的。

It's a 5700 switch Eth that can be used as a handler, and the switch operation system is lost, but I can upload the operating system files through the Eth, which is similar to the console.

华为交换机从网桥发展而来，属于OSI第二层即数据链路层设备。它根据MAC地址寻址，通过站表选择路由，站表的建立和维护由CISCO思科交换机自动进行。

From , it belongs to the second level of OSI, . It is based on 瑞典、俄罗斯、印度以及中国的北京、上海和南京等地设立了多个研究所，近一半的员工从事着产品与解决方案的研发工作。

China has established research institutes in the United States, Germany, , Russia, India, and Beijing, Shanghai and Nanjing in China. Nearly half of its staff are engaged in product and solution research and development.
