1、基于全局的DHCP配置
[Huawei]dhcp enable
[Huawei]int g0/0/0
[Huawei-GigabitEthernet0/0/0]ip add 192.168.1.1 24
[Huawei-GigabitEthernet0/0/0]q
[Huawei]ip pool p1
[Huawei-ip-pool-p1]network 192.168.1.0 mask 24
[Huawei-ip-pool-p1]gateway-list 192.168.1.1
[Huawei-ip-pool-p1]dns-list 8.8.8.8
[Huawei-ip-pool-p1]lease day 6
[Huawei-ip-pool-p1]excluded-ip-address 192.168.1.5 192.168.1.20
[Huawei-ip-pool-p1]int g0/0/0
[Huawei-GigabitEthernet0/0/0]dhcp select global
2、基于接口的DHCP配置
[Huawei]int g0/0/0
[Huawei-GigabitEthernet0/0/0]ip add 192.168.2.1 24
[Huawei-GigabitEthernet0/0/0]dhcp select interface
[Huawei-GigabitEthernet0/0/0]dhcp server dns-list 8.8.8.8
[Huawei-GigabitEthernet0/0/0]dhcp server lease day 8
[Huawei-GigabitEthernet0/0/0]dis ip pool
注：基于接口DHCP不需要配置网段、掩码及默认网关。
3、DHCP中继
转发DHCP服务器和DHCP客户端之间的DHCP报文，客户机可跨网段获取地址。<
