华为交换机：接口的mac地址

华为交换机：接口的mac地址
二层（接口不支持undo portswitch）：
如果接口不支持更变成三层接口，则mac地址与其他接口一样，而且各个vlanif的mac地址也一样。
三层（接口支持undo portswitch）：
如果接口支持更变成三层接口，各个vlanif的mac地不一样。
在更变前也与其他接口mac地址一样，更变成三层则mac地址会变化，与其他接口的mac地址不一样。
三层交换（接口支持undo portswitch）机的二层的接口加入到其他vlan后，mac地址也不变。

HUAWEI S5720S-28P-LI-AC各个接口的mac地址一样：
