DHCP给不同vlan分配IP

网络拓扑图如下：

接入层交换机划分vlan、与核心交换机相连的接口打trunk

SW3：

<Huawei>system-view
[Huawei]undo info-center enable 
[Huawei]sysname SW3
[SW3]vlan 10
[SW3-vlan10]quit

[SW3]port-group group-member Ethernet 0/0/2 to Ethernet 0/0/3    #端口组操作
[SW3-port-group]port link-type access
[SW3-port-group]port default vlan 10
[SW3-port-group]quit

[SW3]interface Ethernet0/0/1
[SW3-Ethernet0/0/1]port link-type trunk
[SW3-Ethernet0/0/1]port trunk allow-pass vlan 10

SW4：

<Huawei>system-view
[Huawei]undo info-center enable 
[Huawei]sysname SW4
[SW4]vlan 20
[SW4-vlan20]quit

[SW4]interface Ethernet0/0/2
[SW4-Ethernet0/0/2]port link-type access
[SW4-Ethernet0/0/2]port default vlan 20
[SW4-Ethernet0/0/2]quit

[SW4]interface Ethernet0/0/1
[SW4-Ethernet0/0/1]port link-type trunk 
[SW4-Ethernet0/0/1]port trunk allow-pass vlan 20

SW5：

<Huawei>system-view
[Huawei]undo info-center enable
[Huawei]sysname SW5
[SW5]vlan 30
[SW5-vlan30]quit

[SW5]port-group group-member Ethernet 0/0/2 to Ethernet 0/0/3
[SW5-port-group]port link-type access
[SW5-port-group]port default vlan 30
[SW5-port-group]quit

[SW5]interface Ethernet0/0/1
[SW5-Ethernet0/0/1]port link-type trunk
[SW5-Ethernet0/0/1]port trunk allow-pass vlan 30

SW6：

<Huawei>system-view
[Huawei]undo info-center enable
[Huawei]sysname SW6
[SW6]vlan 80
[SW6-vlan80]quit

[SW6]interface Ethernet0/0/2
[SW6-Ethernet0/0/2]port link-type access
[SW6-Ethernet0/0/2]port default vlan 80
[SW6-Ethernet0/0/2]quit 

[SW6]interface Ethernet0/0/1
[SW6-Ethernet0/0/1]port link-type trunk
[SW6-Ethernet0/0/1]port trunk allow-pass vlan all

SW7：

<Huawei>system-view 
[Huawei]undo info-center enable
[Huawei]sysname SW7
[SW7]vlan 90
[SW7-vlan90]quit

[SW7]interface Ethernet0/0/2
[SW7-Ethernet0/0/2]port link-type access 
[SW7-Ethernet0/0/2]port default vlan 90
[SW7-Ethernet0/0/2]quit

[SW7]interface Ethernet0/0/1
[SW7-Ethernet0/0/1]port link-type trunk
[SW7-Ethernet0/0/1]port trunk allow-pass vlan all

核心交换机配置：

SW1：

<Huawei>system-view
[Huawei]undo info-center enable
[Huawei]sysname SW1
[SW1]vlan batch 10 20 30 80 90

[SW1]port-group group-member GigabitEthernet 0/0/1 to GigabitEthernet 0/0/5
[SW1-port-group]port link-type trunk 
[SW1-port-group]quit

SW2：

<Huawei>system-view
[Huawei]undo info-center enable
[Huawei]sysname SW2
[SW2]vlan batch 80 90

[SW2]port-group group-member GigabitEthernet 0/0/1 to GigabitEthernet 0/0/3
[SW2-port-group]port link-type trunk
[SW2-port-group]port trunk allow-pass vlan all

DHCP服务器配置

<Huawei>system-view 
[Huawei]undo info-center enable 
[Huawei]sysname AR1
[AR1]dhcp enable

VLAN 10配置DHCP：
[AR1]interface GigabitEthernet 0/0/0.10    #创建子接口

[AR1-GigabitEthernet0/0/0.10]dot1q termination vid 10    #绑定vlan10
[AR1-GigabitEthernet0/0/0.10]arp broadcast enable    #开启arp广播
[AR1-GigabitEthernet0/0/0.10]dhcp select global    #全局分配地址

[AR1]interface GigabitEthernet 0/0/0.80
[AR1-GigabitEthernet0/0/0.80]ip address 80.80.80.1 24

配置完成后，我们在PC上改为自动获取IP，然后再去ping不同vlan的电脑IP
