### 一、配置PC的IP、子网掩码、网关

### 二、配置二层交换机

- **SW2**

  ```
  <Huawei>u t m
  <Huawei>sys
  [Huawei]sys SW2
  [SW2]vlan batch 10 20 30
  [SW2]port-group 1
  [SW2-port-group-1]group-member g0/0/2 g0/0/3
  [SW2-port-group-1]port link-type access
  [SW2-port-group-1]port default vlan 10
  [SW2-port-group-1]quit
  [SW2]int g0/0/1
  [SW2-GigabitEthernet0/0/1]port link-type trunk 
  [SW2-GigabitEthernet0/0/1]port trunk allow-pass vlan all
  [SW2-GigabitEthernet0/0/1]return
  <SW2>save
  ```

- **SW3**

  ```
  <Huawei>u t m
  <Huawei>sys
  [Huawei]sys SW3
  [SW3]vlan batch 10 20 30
  [SW3]port-group 1
  [SW3-port-group-1]group-member g0/0/2 g0/0/3
  [SW3-port-group-1]port link-type access 
  [SW3-port-group-1]port default vlan 20
  [SW3-port-group-1]quit
  [SW3]int g0/0/1
  [SW3-GigabitEthernet0/0/1]port link-type trunk
  [SW3-GigabitEthernet0/0/1]port trunk allow-pass vlan all
  [SW3-GigabitEthernet0/0/1]return
  <SW3>save
  ```

- **SW4**

  ```
  <Huawei>u t m
  <Huawei>sys
  [Huawei]sys SW4
  [SW4]vlan batch 10 20 30
  [SW4]port-group 1
  [SW4-port-group-1]group-member g0/0/2 g0/0/3
  [SW4-port-group-1]port link-type access 
  [SW4-port-group-1]port default vlan 30
  [SW4-port-group-1]quit
  [SW4]int g0/0/1
  [SW4-GigabitEthernet0/0/1]port link-type trunk
  [SW4-GigabitEthernet0/0/1]port trunk allow-pass vlan all
  [SW4-GigabitEthernet0/0/1]return
  <SW4>save
  ```

### 三、配置三层交换机

- **SW1**

  ```
  <Huawei>u t m
  <Huawei>sys
  [Huawei]sys SW1
  [SW1]vlan batch 10 20 30 100
  [SW1]vlan 100
  [SW1-vlan100]aggregate-vlan 
  [SW1-vlan100]access-vlan 10 20 30
  [SW1-vlan100]quit
  [SW1]int vlanif 100
  [SW1-Vlanif100]ip a 192.168.100.254 24
  [SW1-Vlanif100]arp-proxy inter-sub-vlan-proxy enable 
  [SW1-Vlanif100]quit
  [SW1]port-group group-member g0/0/1 to g0/0/3
  [SW1-port-group]port link-type trunk 
  [SW1-port-group]port trunk allow-pass vlan 10 20 30
  [SW1-port-group]return
  <SW1>save
  ```

### 四、测试

- PING

  ```
  PC6>ping 192.168.100.1
  
  Ping 192.168.100.1: 32 data bytes, Press Ctrl_C to break
  From 192.168.100.6: Destination host unreachable
