5.4 MUX VLAN

1.基本概念

1）主VLAN（Principal VLAN）

加入Principal VLAN的接口可以和MUX VLAN内所有的接口进行通信。

2）从VLAN（Subordinate VLAN）

分为互通性（Group VLAN）和隔离型（Separate VLAN），都必须与一个Principal VLAN绑定。

2.基本配置

1）VLAN配置

[SW1]vlan batch 12 34 56 100
[SW1]vlan 100
[SW1-vlan100]mux-vlan
[SW1-vlan100]subordinate group 12 34
[SW1-vlan100]subordinate separate 56

2）接口配置

[SW1]interface GigabitEthernet 0/0/1
[SW1-GigabitEthernet0/0/1]port link-type access 
[SW1-GigabitEthernet0/0/1]port default vlan 12
[SW1-GigabitEthernet0/0/1]port mux-vlan enable 
[SW1-GigabitEthernet0/0/1]quit
[SW1]interface GigabitEthernet 0/0/2
[SW1-GigabitEthernet0/0/2]port link-type access 
[SW1-GigabitEthernet0/0/2]port default vlan 12
[SW1-GigabitEthernet0/0/2]port mux-vlan enable 

[SW1]interface GigabitEthernet 0/0/3
[SW1-GigabitEthernet0/0/3]port link-type access 
[SW1-GigabitEthernet0/0/3]port default vlan 34  
[SW1-GigabitEthernet0/0/3]port mux-vlan enable 
[SW1-GigabitEthernet0/0/3]quit
[SW1]interface GigabitEthernet 0/0/4
[SW1-GigabitEthernet0/0/4]port link-type access 
[SW1-GigabitEthernet0/0/4]port default vlan 34
[SW1-GigabitEthernet0/0/4]port mux-vlan enable 

[SW1]interface GigabitEthernet 0/0/5
[SW1-GigabitEthernet0/0/5]port link-type access 
[SW1-GigabitEthernet0/0/5]port default vlan 56
[SW1-GigabitEthernet0/0/5]port mux-vlan enable 
[SW1-GigabitEthernet0/0/5]quit
[SW1]interface GigabitEthernet 0/0/6
[SW1-GigabitEthernet0/0/6]port link-type access 
[SW1-GigabitEthernet0/0/6]port default vlan 56
[SW1-GigabitEthernet0/0/6]port mux-vlan enable 

[SW1]interface GigabitEthernet 0/0/24
[SW1-GigabitEthernet0/0/24]port link-type access 
[SW1-GigabitEthernet0/0/24]port default vlan 100
[SW1-GigabitEthernet0/0/24]port mux-vlan enable 

3）查看VLAN

[SW1]display mux-vlan 
Principal Subordinate Type         Interface  
100       -           principal    GigabitEthernet0/0/24
100       56          separate     GigabitEthernet0/0/5 GigabitEthernet0/0/6
100       12          group        GigabitEthernet0/0/1 GigabitEthernet0/0/2
100       34          group        GigabitEthernet0/0/3 GigabitEthernet0/0/4
