测试：PCA与PCC可以互通，PCB和PCD可以互通
实验解析
1、配置IP地址
步骤1：配置PCA的IP地址
步骤2：配置PCB的IP地址
步骤3：配置PCC的IP地址
步骤4：配置PCD的IP地址
刚配置完IP地址后，PC之间可以相互通信的,这里用PCA与PCB、PCC、PCD测试连通性

2、在SWA和SWB上分别创建vlan10，vlan20
步骤1：在SWA上创建vlan10和vlan20
[SWA]vlan 10 [SWA-vlan10]vlan 20
步骤2：在SWB上创建vlan10和vlan20
[SWB]vlan 10 [SWB-vlan10]vlan 20
3、在SWA上把端口G1/0/1、G1/0/2分别加入vlan10、vlan20
[SWA]vlan 10 [SWA-vlan10]port g1/0/1 [SWA-vlan10]vlan 20 [SWA-vlan20]port g1/0/2
4、在SWB上把端口G1/0/1、G1/0/2分别加入vlan10、vlan20
[SWB]vlan 10 [SWB-vlan10]port g1/0/1 [SWB-vlan10]vlan 20 [SWB-vlan20]port g1/0/2
5、将SWA和SWB上的G1/0/3端口类型改为Trunk，并允许vlan10、vlan20通过
步骤1：将SWA的G1/0/3端口类型改为Trunk，并允许vlan10、vlan20通过
[SWA]int g1/0/3 [SWA-GigabitEthernet1/0/3]port link-type trunk [SWA-GigabitEthernet1/0/3]port trunk permit vlan 10 20
步骤2：将SWB的G1/0/3端口类型改为Trunk，并允许vlan10、vlan20通过
[SWB]int g1/0/3 [SWB-GigabitEthernet1/0/3]port link-type trunk [SWB-GigabitEthernet1/0/3]port trunk permit vlan 10 20
6、测试：PCA与PCC可以互通，PCB和PCD可以互通
步骤1：PCA与PCC可以互通，与PCB、PCD不通
