ENSP的The specified address conflicts with another address.以及其中一个Protocol是down的问题

如下图是不小心分配错了，本来要把地址赋给子接口1.1和1.2的，结果弄成1.2和1.3了，导致其中一个Protocol是down，而且修改IP地址也不行，出现错误The specified address conflicts with another address.

看看dis cur，就是分配错误

 那么应该怎么办呢？

这样就行⬇

可以看到已经改过来了，而且Protocol都是up了

然后去PC6查看IP地址

去PC5  ping  PC6

 只要有ping后，

查看DHCP服务器的状态dis dhcp server statistics，客户请求Client Request 就是4了
