》Huawei-R&S-网络工程师实验笔记20190524-VRP的系统、接口视图下基本操作（重命名、配置IP、VLAN接口、双工模式、console口）
》》实验开始，先上拓扑图参考：
本次实验使用 Huawei eNSP、Wireshark、Oracle VM VirtualBox 等工具，并开启了左侧分支网络的设备。以下将全部使用代码展示实验过程和理解：

^
Error: Unrecognized command found at '^' position. //提示IP地址配置失败，因为这是一个二层接口。虽然可以通过以下命令
interface GigabitEthernet0/0/1
undo portswitch
把2层接口变成3层接口，但只能在真机上支持该命令，模拟器执行命令后没有效果，配置IP地址还是会报错的。尽管在物理接口上我们不能配置IP地址，
可以考虑使用vlan接口。非常不推荐 把2层接口变为3层接口，那样会让广播域增加太多。
