con口为CONSOLE接口，使用Console线直接连接至计算机的串口，利用终端仿真程序（一般使用Windows自带的“超级终端”）在本地配置路由器。
Console interface, which uses Console lines to directly connect to the computer's serial port, and local configuration of routers using terminal emulators (generally using Windows' own “super terminal”). & nbsp;
ETH口为以太网接口，以太网接口为网络数据连接的端口，将不同的计算机设备连接在一起。以太网（ Ethernet ）设备组网的基本元素有交换机、路由器、集线器、光纤和普通网线以及以太网协议和通讯规则。
The basic elements of the Ethernet equipment network are switches, routers, hubs, fibre optics and ordinary network lines, as well as the Ethernet protocol and communication rules.
扩展资料 extension 可进行网络管理的交换机上一般都有一个“Console”端口，它是专门用于对交换机进行配置和管理的。通过Console端口连接并配置交换机，是配置和管理交换机必须经过的步骤。 A “Console” port is usually used to configure and manage the switch on the switchboard that can be managed by the network. Connect and configure the switch through the Console port is a necessary step to configure and manage the switch. 因为其他方式的配置往往需要借助于IP地址、域名或设备名称才可以实现，而新购买的交换机显然不可能内置有这些参数，所以Console端口是最常用、最基本的交换机管理和配置端口。 Since other modes of configuration often require IP addresses, domain names or equipment names, and it is clear that the newly purchased switches are unlikely to contain these parameters, Console port is the most common and basic exchange management and configuration port. 不同类型的交换机Console端口所处的位置并不相同，有的位于前面板，而有的则位于后面板。通常是模块化交换机大多位于前面板，而固定配置交换机则大多位于后面板。在该端口的上方或侧方都会有类似“CONSOLE”字样的标识。 Different types of switches Console ports are located in different locations, some at the front and others at the back. Most of the modular switches are located on the front and most of the fixed configuration switches on the back. 以太网接口类型：SC光纤接口、RJ-45接口、FDDI接口、AUI接口、BNC接口、Console接口。 Ethernet interface type: SC fibre-optic interface, RJ-45 interface, FDDI interface, AUI interface, BNC interface, Console interface. 参考资料来源：百度百科-CONSOLE接口 参考资料来源：百度百科-以太网接口
Con口就是Console口，即交换机的配置口。交换机的Console口使用配置线与电脑的串行接口Com口连接。在电脑的程序-附件-通讯中启动超级终端程序，使用默认的参数就可以进入到交换机的命令行界面进行配置了；
Console is the Console mouth, which is the configuration of the switchboard. Console on the switchboard uses the configuration line to connect to the computer's serial interface Com. Super terminal programs are activated in the computer's application-appendix-communication, and the command line interface is configured using default parameters that allow access to the switchboard;
ETH口就是Ethernet口，就是以太口。它是一种连接局域网的PC机等设备的工作接口，是最常用的的网络接口。一般来说在企业级的交换机上有16口、24口、48口个以太口。
The ETH is the Ethernet mouth, the Ether. It's a working interface for equipment such as the PC that connects to the local area network and is the most commonly used network interface. Generally, there are 16, 24, and 48 in the business-level switchboard.
eth为E类口 也就是以太网口
