1、搭建好网络拓扑，如图所示
2、PC1与PC2分别接入接入交换机的G0/0/1与G0/0/2口，LSW2交换机设置：1）批量添加VLAN：[LSW2]vlan batch 10 20Info: This operation may take a few seconds. Please wait for a moment...done.[LSW2]
3、2）PC所在接口加入VLAN：[LSW2]interface g0/0/1[LSW2-GigabitEthernet0/0/1]port link-type access[LSW2-GigabitEthernet0/0/1]port default vlan 10[LSW2-GigabitEthernet0/0/1][LSW2-GigabitEthernet0/0/1]inte g0/0/2[LSW2-GigabitEthernet0/0/2]port link-type access[LSW2-GigabitEthernet0/0/2]port default vlan 20
4、3）LSW2互联接口设置：[LSW2]interface g0/0/3[LSW2-GigabitEthernet0/0/3]port link-type trunk[LSW2-GigabitEthernet0/0/3]port trunk allow-pass vlan 10 203、三层交换机LSW1设置：1）批量添加VLAN：[LSW1]vlan batch 10 202）互联接口设置：[LSW1]interface g0/0/1[LSW1-GigabitEthernet0/0/1]port link-type trunk[LSW1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 203）VLANIF 接口设置：[LSW1]interface Vlanif 10[LSW1-Vlanif10]ip address 192.168.1.1 24[LSW1]interface vlan20[LSW1-Vlanif20]ip add 192.168.2.1 24
5、PC设置如图所示
6、测试使用ping进行测试连通性，PC1 ping PC2或者PC2 ping PC1都可以
