第一条命令是：show interfaces switchport
第二条命令是：show interfaces trunk
1。查看Native Vlan的2中方法：1）show interface trunk2）show interface fa0/1 switchport2。更改Native Vlan后，VTP传输通道。个人认为还是用VLAN1，理由如下：1）一开始，只有VLAN1的情况，VTP只能通过VLAN 1 传信息，也就说明VLAN 1 具有传VTP的能力。2）改变后，当client端声明VLAN2是本征VLAN，却没有创建VLAN2的时候，也只能是VLAN 1传数据。 到鸿鹄论坛网站查看回答详情>>
