一、拓扑图如下

 

 

二、配置思路

1、启动DHCP服务；

2、创建VLANIF接口，并配置VLANIF接口的IP地址；

3、使能VLANIF接口地址池；

4、配置地址池的相关属性

三、操作步骤

1、启动DHCP服务

[DHCPServer] dhcp enable

2、创建VLAN

[DHCPServer]vlan batch 10 20

3、配置接口并加入vlan

#配置GE0/0/1接口加入vlan10

[DHCPServer] interface gigabitethernet 0/0/1

[DHCPServer-GigabitEthernet0/0/1] port hybrid pvid vlan 10 [DHCPServer-GigabitEthernet0/0/1] port hybrid untagged vlan 10 [DHCPServer-GigabitEthernet0/0/1] quit

#配置GE0/0/2接口加入vlan20

[DHCPServer] interface gigabitethernet 0/0/2

[DHCPServer-GigabitEthernet0/0/2] port hybrid pvid vlan 20 [DHCPServer-GigabitEthernet0/0/2] port hybrid untagged vlan 20 [DHCPServer-GigabitEthernet0/0/2] quit

4、配置VLANIF接口IP地址

# 配置VLANIF10接口地址。 [DHCPServer] interface vlanif 10 [DHCPServer-Vlanif10] ip address 192.168.10.1 24 [DHCPServer-Vlanif10] quit # 配置VLANIF11接口地址。 [DHCPServer] interface vlanif 20 [DHCPServer-Vlanif20] ip address 192.168.20.1 24 [DHCPServer-Vlanif20] quit

5、使能VLANIF接口地址池

# 配置VLANIF10接口下的客户端从接口地址池中获取IP地址。

[DHCPServer] interface vlanif 10 [DHCPServer-Vlanif10] dhcp select interface [DHCPServer-Vlanif10] quit # 配置VLANIF20接口下的客户端从接口地址池中获取IP地址。 [DHCPServer] interface vlanif 20 [DHCPServer-Vlanif11] dhcp select interface [DHCPServer-Vlanif11] quit  

6、配置接口地址池地址租用期限

# 配置VLANIF10接口地址租用期限为30天。

[DHCPServer] interface vlanif 10

[DHCPServer-Vlanif10] dhcp server lease day 30 [DHCPServer-Vlanif10] quit # 配置VLANIF20接口地址租用期限为20天。

[DHCPServer] interface vlanif 20

[DHCPServer-Vlanif11] dhcp server lease day 20 [DHCPServer-Vlanif11] quit

7、验证配置结果。

 

在DHCPServer上使用display ip pool interface命令用来查看接口地址池配置情况
