1. 配置接口加入VLAN
   [LSW1]vlan batch 10 20 100
   [LSW1-GigabitEthernet0/0/1]port link-type access
   [LSW1-GigabitEthernet0/0/1]port default vlan 10
   [LSW1-GigabitEthernet0/0/2]port link-type access
   [LSW1-GigabitEthernet0/0/2]port default vlan 10
   [LSW1-GigabitEthernet0/0/3]port link-type access
   [LSW1-GigabitEthernet0/0/3]port default vlan 20
   [LSW1-GigabitEthernet0/0/4]port link-type access
   [LSW1-GigabitEthernet0/0/4]port default vlan 20
2. 配置Super-VLAN，实现VLAN聚合
   [LSW1]vlan 100
   [LSW1-vlan100]aggregate-vlan
   [LSW1-vlan100]access-vlan 10 20
   [LSW1]int Vlanif 100
   [LSW1-Vlanif100]ip address 10.1.1.1 24
3. 配置Proxy ARP，实现Sub-VLAN间的三层互通
   [LSW1-Vlanif100]arp-proxy inter-sub-vlan-proxy enable
4. 在接口VLANIF100上配置基于接口地址池的DHCP服务器，实现为Sub-VLAN下的终端动态分配IP地址
   [LSW1]dhcp enable
   [LSW1]int Vlanif 100
   [LSW1-Vlanif100]dhcp select interface
5. PC以DHCP方式获取IP地址
6. 检查配置
