网络:VRP介绍

  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。

  1. 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。 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。 save save The current configuration will be written to the device. Are you sure to continue? (y/n)[n]: 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.

  1. 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。
