vlan

 

实验解决思路：

1.交换机添加 vlan 2 3 4 5

分别在三个交换机上创建vlan 2 3 4

[sw2]vlan batch 2 to 5
[sw2]display vlan 

2.划入接口

sw1：

[sw1-GigabitEthernet0/0/2]port link-type access 

[sw1-GigabitEthernet0/0/2]port default vlan 2

 

[sw1-GigabitEthernet0/0/3]port hybrid untagged vlan 3 to 5

[sw1-GigabitEthernet0/0/3]port hybrid pvid vlan 3

 

[sw1-GigabitEthernet0/0/4]port link-type trunk 

[sw1-GigabitEthernet0/0/4]port trunk allow-pass vlan 2 to 5

[sw1]display port vlan active 

sw2:

[sw2-GigabitEthernet0/0/1]port link-type trunk 

[sw2-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 to 5

 

[sw2-GigabitEthernet0/0/2]port link-type access 

[sw2-GigabitEthernet0/0/2]port default vlan 2

 

[sw2-GigabitEthernet0/0/3]port hybrid untagged vlan 3 to 4

[sw2-GigabitEthernet0/0/3]port hybrid pvid vlan 4

 

[sw2-GigabitEthernet0/0/4]port link-type trunk 

[sw2-GigabitEthernet0/0/4]port trunk allow-pass vlan 2 to 5

[sw2]display port vlan active 

 

sw3：

[sw3-GigabitEthernet0/0/1]port link-type trunk 

[sw3-GigabitEthernet0/0/1]port trunk allow-pass vlan 2 to 5

 

[sw3-GigabitEthernet0/0/2]port hybrid pvid vlan 4
[sw3-GigabitEthernet0/0/2]port hybrid untagged vlan 3 to 4

 

[sw3-GigabitEthernet0/0/3]port hybrid pvid vlan 5  
[sw3-GigabitEthernet0/0/3]port hybrid untagged vlan 3 5

 

[sw2]display port vlan active 

 

3.手配地址进行测试

 

pc1访问pc2

pc2访问pc4 5 6 

pc4可以访问pc5

pc4 5不可以访问pc6
