1、华为交换机命令行的三种视图

<Huaweu>           #用户视图。特征：尖括号、用户名。
[Huawei]           #系统视图。特征：方括号、用户名。
[Huawei-xxx]       #业务视图。特征：方括号、用户名、短横、业务名。xxx表示具体业务

用户视图，开机默认视图，对软考中没啥用。
系统视图，修改用户名、密码、时间、查看当前配置。
业务视图，其中具体业务视图主要包括接口视图、路由协议视图、vlan视图。

三种视图间切换：

<Huawei>system-view                               #用户视图切换到系统视图
[Huawei]interface GigabitEthernet 0/0/1           #系统视图切换到具体的业务视图
[Huawei-GigabitEthernet0/0/1]q                    #具体的业务视图回退到系统视图。补全为quit
[Huawei]q                                         #系统视图回退到用户视图。补全为quit
<Huawei>

执行quit命令，可从当前视图退出至上一层视图。执行return命令可以从任意视图返回到用户视图。

2、修改交换机名称

[Huawei]sysname Switch-01
[Switch-01]

3、关闭和开启信息中心

[HUAWEI]undo info-center enable      #关闭信息中心
[HUAWEI]info-center enable           #打开信息中心

4、vlan

[Huawei]display vlan                    #查看本交换机vlan

[Huawei]vlan 5                          #创建名为5的单个vlan
[Huawei]vlan batch 21 23 29 to 40       #批量创建名为21、23、29~40的vlan

[Huawei]undo vlan 5                     #删除vlan 5
[Huawei]undo vlan batch 21 23 29 to 40  #批量删除vlan 21、23、29~40

[Huawei]interface vlan 5                            #将vlan 5当作一个虚拟接口，SVI技术
[Huawei-Vlanif5]ip address 192.168.1.254 24         #给这个虚拟接口配置一个管理IP地址
[Huawei-Vlanif5]interface g0/0/1                    #配置g0/0/1端口
[Huawei-GigabitEthernet0/0/1]port link-type access  #将g0/0/1端口的链路类型配置成接入模式
[Huawei-GigabitEthernet0/0/1]port default vlan 5    #将g0/0/1端口加入vlan 5
[Huawei-GigabitEthernet0/0/1]q                      #从业务视图推出至系统视图
[Huawei]telnet server enable                        #开启交换机的telnet功能（默认是关闭的）
