1、启用DHCP服务[sw1]dhcp enable
2、基于接口配置DHCP[sw1] int vlan2[sw1-Vlanif2]ip add 192.168.2.1 255.255.255.0[sw1-Vlanif2]dhcp select interface //基于接口配置dhcp[sw1-Vlanif2]dhcp server dns-list 202.106.0.20 // 配置DNS[sw1-Vlanif2]dhcp server lease day 1 //配置dhcp租期1天
3、配置静态地址绑定，192.168.2.100每次都分配给这台终端。dhcp server static-bind ip-address 192.168.2.100 mac-address 5489-98a7-27d2 (dhcp静态绑定）
