》Huawei-R&S-网络工程师实验笔记20190615-IP基础（AR201上配置IP）

》》实验开始，先上拓扑图参考：

》》》一般正常配置IP操作如下，问题在于无法继续：

[AR1]int e0//
[AR1-Ethernet0//]ip address 192.168.1.1
                      ^
Error: Unrecognized command found at '^' position.
[AR1-Ethernet0//]

》》》》这是怎么回事呢？原来eNSP上对AR201这款路由器只设定了Ethernet接口，而且本来eNSP就对Ethernet接口定义了二层接口功能，故而无法配置IP。解决办法也是有的，两种方案可以成功：
1、在eNSP中直接换个型号，除了AR201其他型号都有GE口，都可以配置IP地址。
2、坚持AR201的话，可采用vlan方案，该方案又有两种模式，具体如下：

[AR1]vlan
[AR1-vlan10]int vlan        //务必进入vlanif配置
[AR1-Vlanif10]ip address 1.1.1.1 255.255.255.0
[AR1-Vlanif10]quit
[AR1]

[AR1]interface Ethernet0//                  //先试试Access方案

[Huawei-Ethernet0//]port ?
  default    Specify current port's PVID VLAN characteristics
  link-type  Switch port link type
  priority   Specify current port's priority

[AR1-Ethernet0//]port link-type access        //配置为Access模式
[AR1-Ethernet0//]port default vlan        //Access下可以通过vlan10

[AR1]int e0//0     //其实，不管是Access还是Trunk都是为了E0/0/0接口可以连通其他设备，纯粹配置IP是没有意义的。现在我们开始Trunk方案。

[AR1-Ethernet0//]port link-type trunk    //前面不是设置成Access了嘛，想直接改是不行的
Error: Please renew the default configurations.

[AR1-Ethernet0//]undo port default vlan       //得先取消vlan配置（如果在trunk前提下改Access，怎么改？命令是什么？）
