进入系统视图
[H3C]dhcp server ip-pool h3c
创建DHCP 地址池
[H3C-dhcp-pool-h3c]network 192.168.1.0 mask 255.255.255.0
指定可以分配的地址段
[H3C-dhcp-pool-h3c]gateway-list 192.168.1.1
指定网关,与lan口的地址一致
[H3C-dhcp-pool-h3c]dns-list 202.202.202.202
指定DNS server地址
[H3C-dhcp-pool-h3c]expired day 0 hour 1 minute 10
DHCP租期时间设置
[H3C-dhcp-pool-h3c]domain-name huawei-3com.com
指定域名
[H3C-dhcp-pool-h3c]quit
[H3C]interface Ethernet1/0
进入到lan口
[H3C-Ethernet1/0]ip address 192.168.1.1 255.255.255.0
配置lan口地址
[H3C-Ethernet1/0]quit
[H3C]dhcp server forbidden-ip 192.168.1.1
保留网关的地址
[H3C]quit
<H3C>save
保存配置
如果你network了192.168.1.0网段 那么想dhcp起作用的话你设备上就得有处于192.168.1.0网段的端口，那样的话路由器收到dhcp请求后才会应答
另外你还需要配置默认网关 DNS 这样才能保证客户端能上网
