一、实验环境：

二、配置交换机SW1 为混合链路

<H3C>system-view

[SW1-vlan30]vlan 40
[SW1-vlan40]quit
[SW1]interface g 1/0/1
[SW1-GigabitEthernet1/0/1]port link-type hybrid		端口链路类型为混合链路
[SW1-GigabitEthernet1/0/1]port hybrid pvid vlan 100	端口混合链路打标记
[SW1-GigabitEthernet1/0/1]port hybrid vlan 100 30 40 untagged	端口混合链路进交换机来时不打100、30、40的标记
[SW1-GigabitEthernet1/0/1]quit
[SW1]interface g 1/0/2
[SW1-GigabitEthernet1/0/2]port link-type hybrid 
[SW1-GigabitEthernet1/0/2]port hybrid pvid vlan 30

[SW1-GigabitEthernet1/0/3]port hybrid vlan 100 40 untagged
[SW1-GigabitEthernet1/0/3]quit

三、配置PC IP：

四、192.168.1.100 ping 192.168.1.30、192.168.1.40 验证：
