Hyprid接口實現特殊通信

**實驗環境
房間之間不能通信，但每個房間都可以與出口路由器通信

SW1——配置各個接口

<Huawei>system-view     //進入全局配置模式 
[Huawei]undo info-center enable     //關閉信息告警提示
[Huawei]sysname SW1     //改名
[SW1]vlan batch 10 20 30     //創建VLAN10、VLAN20和VLAN30
[SW1]interface g0/0/1     //進入接口	
[SW1-GigabitEthernet0/0/1]port hybrid pvid vlan 30     //設置爲本徵VLAN，不打標記
[SW1-GigabitEthernet0/0/1]port hybrid untagged vlan 10 20 30     //設置當前接口爲hybrid模式，去掉VLAN10、VLAN20和VLAN30的標記
[SW1-GigabitEthernet0/0/1]quit     //退出
[SW1]interface g0/0/2     //進入接口		
[SW1-GigabitEthernet0/0/2]port hybrid pvid vlan 10     //設置爲本徵VLAN，不打標記
[SW1-GigabitEthernet0/0/2]port hybrid untagged vlan 10 30     //設置當前接口爲hybrid模式，去掉VLAN10和VLAN30的標記	
[SW1-GigabitEthernet0/0/2]quit     //退出
[SW1]interface g0/0/3     //進入接口		
[SW1-GigabitEthernet0/0/3]port hybrid pvid vlan 20     //設置爲本徵VLAN，不打標記
[SW1-GigabitEthernet0/0/3]port hybrid untagged  vlan 20 30     //設置當前接口爲hybrid模式，去掉VLAN20和VLAN30的標記
[SW1-GigabitEthernet0/0/3]quit     //退出
