命令行视图
|命令行视图|权限|
|::|::|
|用户视图|查看运行状态或其他参数|
|系统视图|配置设备的系统参数等|
|接口视图|配置接口参数|
|协议视图|配置路由协议|
这些视图模式存在包含关系，必须由上一层视图转换到下一层视图。
<Huawei>system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]interface GigabitEthernet 0/0/0
[Huawei-GigabitEthernet0/0/0]
退出视图
使用 quit 命令可以退回上一层视图
[Huawei]interface GigabitEthernet 0/0/0
[Huawei-GigabitEthernet0/0/0]quit
[Huawei]
也可以使用 return 直接回到用户视图
[Huawei-GigabitEthernet0/0/0]return
<Huawei>
或使用 [ctrl + z] 快捷键退回用户视图
[Huawei-GigabitEthernet0/0/0]
<Huawei>
修改主机名称
<huawei>sysname Router1
<Router1>
命令行快捷键
|快捷键|功能|
|::|::|
|Ctrl+A|把光标移动到当前命令行的最前端|

用户界面
|用户界面类型|编号|
|::|::|
|Console|0|
|VTY|0-4|
<Router1>system-view
[Router1]user-interface vty ?
INTEGER<0-4,16-20> The first user terminal interface to be configured
[Router1]user-interface vty 1 4
[Router1-ui-vty1-4]
- 默认VTY是 0-5，但是修改后 VTY 最大可配置范围为 0-15
[Router1]user-interface maximum-vty ?
INTEGER<0-15> The maximum number of VTY users, the default value is 5
配置登录权限
|命令|功能|
|::|::|
|user privilege|配置指定用户界面下的用户级别|
|set authentication password|配置本地认证密码|
[Router1-ui-console0]authentication-mode password
Please configure the login password (maximum length 16):123456
或者使用另外一种方式
[Router1-ui-console0]set authentication password cipher ?
STRING<1-16>/<56> Cipher text password
[Router1-ui-vty0]set authentication password cipher 123456
当我们使用 display current-configuration 命令去查看配置文件，能看到下面的内容
user-interface con 0
authentication-mode password
set authentication password cipher %$%$f;)7"{s`6~#o}m=$LiX9,~W#zlGs8@8se$A:YvQ0
M=>T~W&,%$%$
设置的密码已经使用MD5加密
配置VTY telnet的连接，和console的配置基本上是一致的。但是我们需要指定一个 用户级别 给telnet连接，否则用户使用 telnet 进入系统视图后，很多命令不能执行。
[Router1]user-interface vty 1 4
[Router1-ui-vty1-4]authentication-mode password
Please configure the login password (maximum length 16):123456
[Router1-ui-vty1-4]user privilege level 3
