一、实验目的
l理解命令行视图的含义以及进入离开命令行视图的方法
l掌握一些常见的命令
l掌握使用命令行在线帮助的方法
l掌握如何撤销命令
l掌握如何使用命令行快捷键
二、实验拓扑
VRP的基本操作实验拓扑如图所示。
VRP的基本操作
三、实验步骤
（1）：熟悉VRP的视图
<Huawei> //用户视图
<Huawei>system-view //从用户视图进入到系统视图
Enter system view, return user view with Ctrl+Z.
[Huawei] //[ ] 代表系统视图
[Huawei]interface GigabitEthernet 0/0/0 //从系统视图进入到接口视图
[Huawei-GigabitEthernet0/0/0]ip add //我们只输入“ip add”，然后按Tab键，就可以补全“address”
[Huawei-GigabitEthernet0/0/0]ip address 10.1.1.1 24 //配置接口IP地址为10.1.1.1 ，掩码长度为24位。
[Huawei-GigabitEthernet0/0/0]quit //quit命令是VRP系统中的退出当前层级命令。
[Huawei]ospf // 进入到ospf协议视图
[Huawei-ospf-1] // ospf是我们后面要学习的一个非常重要的动态路由协议，此处仅作为一个示例。【技术要点1】
Tab键的使用：如果与之匹配的关键字唯一，按下<Tab>键，系统自动补全关键字，补全后，反复按<Tab>关键字不变。示例如下：
[Huawei] info- //按下Tab键
[Huawei] info-center【技术要点2】
退出命令我们可以用quit、return、和快捷键“Ctrl+z”。
Quit命令仅可以返回上一个视图
Return命令直接返回到用户视图

快捷键“Ctrl+z”和return一样
（2）：给设备命名
[Huawei]sysname joinlabs //更改系统名为joinlabs
[joinlabs] //读者可以看到系统名由Huwei变成了joinlabs（3）：查看当前运行的配置文件
<joinlabs>display current-configuration //查看当前运行的配置文件
#
sysname joinlabs //系统名为joinlabs
#

return（6）：配置文件重置
<joinlabs>reset saved-configuration //清空保存的配置文件
Warning: The action will delete the saved configuration in the device.
The configuration will be erased to reconfigure. Continue? [Y/N]:Y //“配置将会被删除用于重新配置”选择Y
Warning: Now clearing the configuration in the device.
Info: Succeeded in clearing the configuration in the device.
<joinlabs>reboot //重启，只有重新启动配置才能清空。
Info: The system is now comparing the configuration, please wait.
Warning: All the configuration will be saved to the configuration file for the next startup:, Continue?[Y/N]: N //”所有的配置会被保存到下次启动文件中，是否继续”？一定要选择N，即不保存当前的配置
Info: If want to reboot with saving diagnostic information, input 'N' and then execute 'reboot save diagnostic-information'.
System will reboot! Continue?[Y/N]:Y //选择Y（7）：指定系统启动配置文件
<joinlabs>save joinlabs.cfg //保存配置文件，配置文件名为joinlabs.cfg
Are you sure to save the configuration to flash:/joinlabs.cfg?[Y/N]:y //选择Y或者是回车
