1.建拓扑图如下 2.修改名称DHCP [Huawei]sysname DHCP 接口配置ip [DHCP]interface GigabitEthernet 0/0/0 [DHCP-GigabitEthernet0/0/0]ip address 192.168.1.254 24

3.配置DHCP 启用DHCP服务 [DHCP]dhcp enable 配置DHCP模式 [DHCP-GigabitEthernet0/0/0]dhcp select interface

4.测试 PC>ipconfig

Link local IPv6 address...........: fe80::5689:98ff:fe1b:4a1a IPv6 address......................: :: / 128 IPv6 gateway......................: :: IPv4 address......................: 192.168.1.253 Subnet mask.......................: 255.255.255.0 Gateway...........................: 192.168.1.254 Physical address..................: 54-89-98-1B-4A-1A DNS server........................:

5.配置dns、并测试 [DHCP-GigabitEthernet0/0/0]dhcp server dns-list 8.8.8.8

PC>ipconfig /renew

IP Configuration

Link local IPv6 address...........: fe80::5689:98ff:fe1b:4a1a IPv6 address......................: :: / 128 IPv6 gateway......................: :: IPv4 address......................: 192.168.1.253 Subnet mask.......................: 255.255.255.0 Gateway...........................: 192.168.1.254 Physical address..................: 54-89-98-1B-4A-1A DNS server........................: 8.8.8.8

6.配置DHCP地址排除、并测试 [DHCP-GigabitEthernet0/0/0]dhcp server excluded-ip-address 192.168.1.201 192.168.1.252

PC>ipconfig

Link local IPv6 address...........: fe80::5689:98ff:fe11:5ef5 IPv6 address......................: :: / 128 IPv6 gateway......................: :: IPv4 address......................: 192.168.1.200 Subnet mask.......................: 255.255.255.0 Gateway...........................: 192.168.1.254 Physical address..................: 54-89-98-11-5E-F5 DNS server........................: 8.8.8.8

7.配置地址租期 [DHCP-GigabitEthernet0/0/0]dhcp server lease day 7

8.查看dhcp地址使用情况
