1. 使能DHCP服务
[LSW1]dhcp enable
2. 配置接口加入VLAN
[LSW1]vlan batch 10 20
[LSW1-GigabitEthernet0/0/1]port link-type hybrid
[LSW1-GigabitEthernet0/0/1]port hybrid pvid vlan 10
[LSW1-GigabitEthernet0/0/1]port hybrid untagged vlan 10
[LSW1-GigabitEthernet0/0/2]port link-type hybrid
[LSW1-GigabitEthernet0/0/2]port hybrid pvid vlan 20
[LSW1-GigabitEthernet0/0/2]port hybrid untagged vlan 20
3. 配置VLANIF接口IP地址
[LSW1]int Vlanif 10
[LSW1-Vlanif10]ip add 10.1.1.1 24
[LSW1-Vlanif10]int Vlanif 20
[LSW1-Vlanif20]ip add 10.1.2.1 24
4. 配置接口地址池
[LSW1-Vlanif10]dhcp select interface
[LSW1-Vlanif10]dhcp server lease day 30
[LSW1-Vlanif10]dhcp server domain-name abc.com
[LSW1-Vlanif10]dhcp server dns-list 8.8.8.8
[LSW1-Vlanif10]dhcp server static-bind ip-address 10.1.1.100 mac-address 5489-9F7-40E7
[LSW1-Vlanif20]dhcp select interface
[LSW1-Vlanif20]dhcp server lease day 2
[LSW1-Vlanif20]dhcp server domain-name abc.com
[LSW1-Vlanif20]dhcp server dns-list 8.8.8.8
5. 配置DHCP数据保存功能，设备发生故障时，可以在系统重启后，执行命令dhcp server database recover，从存储设备文件恢复DHCP数据
[LSW1]dhcp server database enable
6. PC选择DHCP方式获取IP地址
7. 验证配置
