》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 e0/0/0 [AR1-Ethernet0/0/0]ip address 192.168.1.1 24 ^ Error: Unrecognized command found at '^' position. [AR1-Ethernet0/0/0]
》》》》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 10 [AR1-vlan10]int vlan 10 //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 Ethernet0/0/0 //先试试Access方案 [Huawei-Ethernet0/0/0]port ? default Specify current port's PVID VLAN characteristics link-type Switch port link type priority Specify current port's priority [AR1-Ethernet0/0/0]port link-type access //配置为Access模式 [AR1-Ethernet0/0/0]port default vlan 10 //Access下可以通过vlan10 [AR1]dis ip int bri *down: administratively down ^down: standby (l): loopback (s): spoofing The number of interface that is UP in Physical is 2 The number of interface that is DOWN in Physical is 1 The number of interface that is UP in Protocol is 2 The number of interface that is DOWN in Protocol is 1 Interface IP Address/Mask Physical Protocol Ethernet0/0/8 unassigned down down NULL0 unassigned up up(s) Vlanif10 192.168.1.1/24 up up //IP配置成功了 [AR1]
[AR1]int e0/0/0 //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-Ethernet0/0/0]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-Ethernet0/0/0]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？） Jun 16 2019 00:16:21-08:00 AR1 %%01IFNET/4/IF_STATE(l)[0]:Interface Vlanif10 has turned into DOWN state.
