》Huawei-R&S-網絡工程師實驗筆記20190615-IP基礎（AR201上配置IP）
》》實驗開始，先上拓撲圖參考：
》》》一般正常配置IP操作如下，問題在於無法繼續：
[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]
》》》》這是怎么回事呢？原來eNSP上對AR201這款路由器只設定了Ethernet接口，而且本來eNSP就對Ethernet接口定義了二層接口功能，故而無法配置IP。解決辦法也是有的，兩種方案可以成功：
1、在eNSP中直接換個型號，除了AR201其他型號都有GE口，都可以配置IP地址。
2、堅持AR201的話，可采用vlan方案，該方案又有兩種模式，具體如下：
[AR1]vlan 10 [AR1-vlan10]int vlan 10 //務必進入vlanif配置 [AR1-Vlanif10]ip address 1.1.1.1 255.255.255.0 [AR1-Vlanif10]quit [AR1]
[AR1]interface Ethernet0/0/0 //先試試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 //配置為Access模式 [AR1-Ethernet0/0/0]port default vlan 10 //Access下可以通過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 //其實，不管是Access還是Trunk都是為了E0/0/0接口可以連通其他設備，純粹配置IP是沒有意義的。現在我們開始Trunk方案。 [AR1-Ethernet0/0/0]port link-type trunk //前面不是設置成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.
