Boson Netsim Lab Navigator Lesson 2——The Basics（The Lesson）

The Lesson

Basic Lab Overview

This lab will introduce the Cisco Internetwork Operating System (IOS) command line interface (CLI).  You will need to logon to a router and become familiar with the different levels of access on the router.  You will also become familiar with the commands available to you in each mode (user or privileged) and the router help facility, history, and editing features.

基础实验概述

这个实验将介绍思科的网络操作系统（IOS）命令行接口（CLI）。你需要登录到路由器并且熟悉以不同的级别访问路由器，同样你也需要熟悉在不同的模式下有哪些可以用到的命令（用户模式或者特权模式），以及路由器的帮助设施，历史及编辑功能。

User vs. Privileged Mode

User mode is indicated with the '>' next to the router name.  You can look at settings but can not make changes from user mode.  In Privilege mode (indicated by the '#', you can do anything).  To get into privilege mode the keyword is ENABLE.

用户模式VS.特权模式

用户模式是在路由器名字后面以“>”符号标示，在用户模式下你可以查看一些设置信息但不能进行任何更改。在特权模式（特权模式以#标示，你可以进行任何操作），进入特权模式的命令是Enable。

HELP

To view all commands available from this mode type: ?  and press: enter This will give you the list of all available commands for the router in your current mode. You can also use the question mark after you have started typing a command.  For example if you want to use a show command but you do not remember which one it uses 'show ?'  will output all commands that you can use with the show command.

帮助

输入？并按下回车键之后可以查看当前模式下所有适用于路由器的可用命令。你也可以用？跟在某一命令的后面，例如你想知道Show命令，但是又记不清哪种情况下用哪一个Show命令，这时输入Show ?就会显示出所有能用的与Show有关的命令。

Configuration Mode

From privilege mode you can enter configuration mode by typing CONFIG T  you can exit configuration mode type END or <CTL>+z

Router#config t
dZwbcbX0Router(config)#end

配置模式

从特权模式进入配置模式使用Config t命令即可，在配置模式下输入End或者Ctrl+z可以退出配置模式。爱好者博墅K&^B6Nal+m~"H

注：Bonson里面好的好像不太准备，在特权模式下可以进行任何操作（原文：you can do anything），还是英文的语境不一样，理解不一样，按常规说法应该是配置模式可以进行任何操作才对，不觖……
