在SW1的g0/0/1 和 SW2的g0/0/2 接口上配置混杂模式，pvid为3，
untagged VLAN 4 5 , tagged vlan 2 3。相当于把vlan 45 在这儿换成 vlan3。
1、交换机和pc间的vlan接口模式
SW1
[sw1]vlan batch 2 to 5
[sw1]int GigabitEthernet 0/0/3
[sw1-GigabitEthernet0/0/3]port link-type access
[sw1-GigabitEthernet0/0/3]port default vlan 2
[sw1]int GigabitEthernet 0/0/4
[sw1-GigabitEthernet0/0/4]port hybrid pvid vlan 3
[sw1-GigabitEthernet0/0/4]port hybrid untagged vlan 2 to 5
SW2
[sw2]vlan batch 2 to 5
[sw2]int GigabitEthernet 0/0/3
[sw2-GigabitEthernet0/0/3]port link-type access
[sw2-GigabitEthernet0/0/3]port default vlan 2
[sw2]int g
[sw2]int GigabitEthernet 0/0/4
[sw2-GigabitEthernet0/0/4]port hybrid pvid vlan 4
[sw2-GigabitEthernet0/0/4]port hybrid untagged vlan 2 to 4
SW3
[sw3]vlan batch 2 to 5
[sw3]int GigabitEthernet 0/0/3
[sw3-GigabitEthernet0/0/3]port hybrid pvid vlan 4
[sw3-GigabitEthernet0/0/3]port hybrid untagged vlan 2 to 5
[sw3]int g
[sw3]int GigabitEthernet 0/0/4
[sw3-GigabitEthernet0/0/4]port hybrid pvid vlan 5
[sw3-GigabitEthernet0/0/4]port hybrid untagged vlan 2 3 5
2、交换机之间的vlan接口模式
SW1
[sw1]int GigabitEthernet 0/0/1
[sw1-GigabitEthernet0/0/1]port hy
[sw1-GigabitEthernet0/0/1]port hybrid pvid vlan 3
[sw1-GigabitEthernet0/0/1]port hybrid untagged vlan 4 5
[sw1-GigabitEthernet0/0/1]port hybrid tagged vlan 2 3
SW2
[sw2]int GigabitEthernet 0/0/2
[sw2-GigabitEthernet0/0/2]port hybrid pvid vlan 3
[sw2-GigabitEthernet0/0/2]port hybrid untagged vlan 4 5
[sw2-GigabitEthernet0/0/2]port hybrid tagged vlan 2 3
[sw2]int GigabitEthernet 0/0/1
[sw2-GigabitEthernet0/0/1]port link-type trunk
[sw2-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 to 5
SW3
[sw3]int GigabitEthernet 0/0/2
[sw3-GigabitEthernet0/0/2]port link-type trunk
[sw3-GigabitEthernet0/0/2]port trunk allow-pass vlan 2 to 5
3、sw1和R1
SW1
[sw1]int GigabitEthernet 0/0/2
[sw1-GigabitEthernet0/0/2]port link-type trunk
[sw1-GigabitEthernet0/0/2]port trunk allow-pass vlan 2 3
R1
单臂路由
[r1]int GigabitEthernet 0/0/1.1
[r1-GigabitEthernet0/0/1.1]dot1q termination vid 2
[r1-GigabitEthernet0/0/1.1]ip address 192.168.2.10 24
[r1-GigabitEthernet0/0/1.1]arp broadcast enable
[r1]int GigabitEthernet 0/0/1.2
[r1-GigabitEthernet0/0/1.2]dot1q termination vid 3
[r1-GigabitEthernet0/0/1.2]ip address 192.168.3.10 24
[r1-GigabitEthernet0/0/1.2]arp broadcast enable
DHCP
[r1]int GigabitEthernet 0/0/1.1
[r1-GigabitEthernet0/0/1.1]dhcp select global
[r1]ip pool v2
Info: It’s successful to create an IP address pool.

[r1-ip-pool-v2]q
[r1]int g
[r1]int GigabitEthernet 0/0/1.2
[r1-GigabitEthernet0/0/1.2]dhcp select global
[r1]ip pool v3

4、测试
pc2可以访问pc4/5/6
pc4可以访问pc5
pc4、pc5不能访问pc6
pc1/3可以正常访问pc2/4/5/6
