Hyprid接口实现特殊通信

**实验环境
房间之间不能通信，但每个房间都可以与出口路由器通信

SW1——配置各个接口

<Huawei>system-view     //进入全局配置模式 
[Huawei]undo info-center enable     //关闭信息告警提示
[Huawei]sysname SW1     //改名
[SW1]vlan batch 10 20 30     //创建VLAN10、VLAN20和VLAN30
[SW1]interface g0/0/1     //进入接口	
[SW1-GigabitEthernet0/0/1]port hybrid pvid vlan 30     //设置为本征VLAN，不打标记
[SW1-GigabitEthernet0/0/1]port hybrid untagged vlan 10 20 30     //设置当前接口为hybrid模式，去掉VLAN10、VLAN20和VLAN30的标记
[SW1-GigabitEthernet0/0/1]quit     //退出
[SW1]interface g0/0/2     //进入接口		
[SW1-GigabitEthernet0/0/2]port hybrid pvid vlan 10     //设置为本征VLAN，不打标记
[SW1-GigabitEthernet0/0/2]port hybrid untagged vlan 10 30     //设置当前接口为hybrid模式，去掉VLAN10和VLAN30的标记	
[SW1-GigabitEthernet0/0/2]quit     //退出
[SW1]interface g0/0/3     //进入接口		
[SW1-GigabitEthernet0/0/3]port hybrid pvid vlan 20     //设置为本征VLAN，不打标记
[SW1-GigabitEthernet0/0/3]port hybrid untagged  vlan 20 30     //设置当前接口为hybrid模式，去掉VLAN20和VLAN30的标记
[SW1-GigabitEthernet0/0/3]quit     //退出
