H3C交换机Trunk端口配置

1、组网需求：1SwitchA与SwitchB用trunk互连，相同VLAN的PC之间可以互访，不同VLAN的PC之间禁止互访；2PC1与PC2之间在不同VLAN，通过设置上层三层交换机SwitchB的VLAN接口10的IP地址为10.1.1.254/24，VLAN接口20的IP地址为20.1.1.254/24可以实现VLAN间的互访。组网图：1VLAN内互访，VLAN间禁访2通过三层交换机实现VLAN间互访配置步骤：实现VLAN内互访VLAN间禁访配置过程SwitchA相关配置：1创建（进入）VLAN10，将E0/1加入到VLAN10SwitchAvlan 10SwitchA-vlan10por
