1、拓扑搭建
1）pc1和pc3所有接口为access；pvlan；vlan2
2）pc2/4/5/6在同一网段，其中pc2可以访问pc4/5/6；pc4可以访问pc5，不能访问pc6
3）pc5不能访问pc6
2、配置：
Sw1：
创建vlan
[sw1]vlan batch 2 to 5
pc1接口设置为access模式，划入vlan2
[sw1]interface g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type access
[sw1-GigabitEthernet0/0/1]port default vlan 2
pc2接口为混杂模式，pvid修改为vlan3
[sw1-GigabitEthernet0/0/2]port hybrid pvid vlan 3
[sw1-GigabitEthernet0/0/2]port hybrid untagged vlan 3 to
5
Sw1和sw2之间，流量通过要携带标签
[sw1-GigabitEthernet0/0/3]port hybrid tagged vlan 2 to 5
Sw2：
创建vlan
[sw2]vlan batch 2 to 5
Pc3接口设置为access模式，划入vlan2
[sw2]interface g0/0/1
[sw2-GigabitEthernet0/0/1]port link-type access
[sw2-GigabitEthernet0/0/1]port default vlan 2
Pc4接口为混杂模式，pvid修改为vlan4
[sw2-GigabitEthernet0/0/2]port hybrid pvid vlan 4
[sw2-GigabitEthernet0/0/2]port hybrid untagged vlan 3 to 4
Sw1、sw2、sw3之间，流量通过要携带标签
[sw2-GigabitEthernet0/0/3]port hybrid tagged vlan 2 to 5
[sw2-GigabitEthernet0/0/4]port hybrid tagged vlan 2 to 5
Sw3：
创建vlan
[sw3]vlan batch 2 to 5
Pc5接口为混杂模式，pvid修改为vlan4，允许vlan3和vlan4
[sw3]interface g0/0/1
[sw3-GigabitEthernet0/0/1]port hybrid pvid vlan 4
[sw3-GigabitEthernet0/0/1]port hybrid untagged vlan 3 to 4
Pc6接口为混杂模式，pvid修改为vlan5
[sw3-GigabitEthernet0/0/2]port hybrid pvid vlan 5
[sw3-GigabitEthernet0/0/2]port hybrid untagged vlan 3 5
Sw1、sw2、sw3之间，流量通过要携带标签
[sw3-GigabitEthernet0/0/4]port hybrid tagged vlan 2 to 5
3、测试
