H3C 交换机设置VLAN 10 ＩＰ为１０．４．０．０VLAN 20ＩＰ为１０．5．０．０VLAN 30ＩＰ为１０．6．０．０VLAN 40ＩＰ为１０．7．０．０。其中VLAN 10 可以被其它VLAN访问VLAN 203040 之间不能相互访问。同时所有的VLAN都能访问外网

以下是H3C交换机的配置指令：

1. 创建VLAN 10，并设置IP地址为10.4.0.1：

vlan 10 description VLAN 10 ip address 10.4.0.1 255.255.255.0

2. 创建VLAN 20，并设置IP地址为10.5.0.1：

vlan 20 description VLAN 20 ip address 10.5.0.1 255.255.255.0

3. 创建VLAN 30，并设置IP地址为10.6.0.1：

vlan 30 description VLAN 30 ip address 10.6.0.1 255.255.255.0

4. 创建VLAN 40，并设置IP地址为10.7.0.1：

vlan 40 description VLAN 40 ip address 10.7.0.1 255.255.255.0

5. 允许VLAN 10被其它VLAN访问：

vlan 10 description VLAN 10 ip address 10.4.0.1 255.255.255.0 vlan members 10 20 30 40 vlan permit 10

6. 禁止VLAN 20,30,40相互访问：

vlan 20 description VLAN 20 ip address 10.5.0.1 255.255.255.0 vlan members 20 vlan deny 30 vlan deny 40

vlan 30 description VLAN 30 ip address 10.6.0.1 255.255.255.0 vlan members 30 vlan deny 20 vlan deny 40

vlan 40 description VLAN 40 ip address 10.7.0.1 255.255.255.0 vlan members 40 vlan deny 20 vlan deny 30

7. 配置外网访问：

interface GigabitEthernet0/0/1 description WAN Interface ip address dhcp ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/1
