1. VRP 华为使用的通用路由平台，华为的交换机、防火墙、安全设备、无线和路由器的命令行几乎一样。

2. VRP分为用户视图、系统视图。

3. 用户视图 user view

        <Huawei>：其中<>代表的是用户视图，Huawei是设备的名称。命令比较少。开机、登录默认进入该视图。

        使用system-view可以由用户视图进入系统视图。

4. 系统视图 system view

        [Huawei] : 其中[] 代表的是系统视图，Huawei是设备的名称。可以对设备进行控制。

<Huawei>system-view
system-view
Enter system view, return user view with Ctrl+Z.
[Huawei]
[Huawei]

        使用quit 逐级退出或者同时按住Ctrl + Z 键直接返回用户视图。

        save 保存命令，需要确认。有时敲一遍不能保存，需要多敲几次才能完成保存。

<R1>save
saveThe current configuration will be written to the device. Are you sure to continue? (y/n)[n]:
<R1>

5. 命令介绍

        Tips：可以使用Tab键补全命令，或者直接使用命令简写。

                  输入？可以对命令进行提示。

                  以下命令在系统视图操作。

       1. 进入接口

[R1]interface  GigabitEthernet  0/0/0
[R1-GigabitEthernet0/0/0]

        或者

[R1]interface g0/0/1
interface g0/0/1
[R1-GigabitEthernet0/0/1]

        2. 给接口配置IP地址（思科和华为设备均可通过此种方法配置）

[R1-GigabitEthernet0/0/0]ip address 192.168.1.1 255.255.255.0
ip add
[R1-GigabitEthernet0/0/0]ip address  192.168.1.1 255.255.255.0
Aug  2 2023 19:53:23-08:00 R1 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP on the interface GigabitEthernet0/0/0 has entered the UP state. 
[R1-GigabitEthernet0/0/0]

        或者 （仅华为设备可这样配置，思科不可这样配置）

[R1-GigabitEthernet0/0/0]ip address 192.168.1.1 24
ip address 192.168.1.1 24
Aug  2 2023 20:03:03-08:00 R1 %%01IFNET/4/LINK_STATE(l)[10]:The line protocol IP on the interface GigabitEthernet0/0/0 has entered the UP state. 
[R1-GigabitEthernet0/0/0]
[R1-GigabitEthernet0/0/0]display this
display this
[V200R003C00]
#
interface GigabitEthernet0/0/0ip address 192.168.1.1 255.255.255.0 
#
return
[R1-GigabitEthernet0/0/0]

        如果IP地址配置错了，重新输入正确的IP地址覆盖即可。

        3. 给设备重命名

[Huawei]sysname R1
sysname R1
[R1]

        4. 查看当前端口的IP等配置信息

[R1-GigabitEthernet0/0/0]display this
display this
[V200R003C00]
#
interface GigabitEthernet0/0/0ip address 192.168.1.1 255.255.255.0 
#
return
[R1-GigabitEthernet0/0/0]

        5. 关闭接口

[R1-GigabitEthernet0/0/0]shutdown
shutdown
Aug  2 2023 19:57:46-08:00 R1 %%01IFPDT/4/IF_STATE(l)[1]:Interface GigabitEthernet0/0/0 has turned into DOWN state.
[R1-GigabitEthernet0/0/0]

        6. 撤销命令：undo+命令

        撤销shutdown命令

[R1-GigabitEthernet0/0/0]undo shutdown
undo shutdown
[R1-GigabitEthernet0/0/0]
[R1-GigabitEthernet0/0/0]
Aug  2 2023 19:59:53-08:00 R1 %%01IFPDT/4/IF_STATE(l)[7]:Interface GigabitEthernet0/0/0 has turned into UP state.

[R1-GigabitEthernet0/0/0]

       撤销端口的IP配置

[R1-GigabitEthernet0/0/0]undo ip address
undo ip address
Aug  2 2023 20:01:06-08:00 R1 %%01IFNET/4/LINK_STATE(l)[9]:The line protocol IP on the interface GigabitEthernet0/0/0 has entered the DOWN state.

        或者

[R1-GigabitEthernet0/0/0]undo ip address 192.168.1.1 24
undo ip address 192.168.1.1 24
Aug  2 2023 20:04:27-08:00 R1 %%01IFNET/4/LINK_STATE(l)[11]:The line protocol IP on the interface GigabitEthernet0/0/0 has entered the DOWN state.

        9. 三层接口可以配置IP地址。

            二层接口不能直接配置IP地址。华为的中低端交换机默认接口为二层接口，无法配置IP地址。使用undo portswitch 命令删除二层接口的配置，使用vlanif或者svi 才可以配置IP地址。

        使用ping 命令ping对方IP。成功则返回ttl等信息。
