華爲ensp綜合實驗（包含鏈路聚合、lacp、dhcp、單臂路由）

準備實驗環境

首先在三臺交換機建立vlan而且將各個接口加入到各自vlan，單數爲vlan10，複數爲vlan20

而後配置鏈路聚合和lacp，（之間是含有前後順序的，先進入eth-trunk組，配置中繼鏈路即容許全部vlan經過，而後配置lacp，最後再將接口加入到eth-trunk組中）

R1路由器的鏈路配置即單臂路由，（路由器的鏈路聚合配置首先加入eth-trunk組，使用命令（undo portswitch）讓路由二層變三層。以後再將接口捆綁起來，最後配置單臂路由）在AR1配置dhcp使pc機能夠自動得到IP地址


其餘路由器的鏈路聚合都是一樣的操做，先進入eth-trunk組讓二層變三層，而後配置ip地址，指路由

所有都作好後在pc上點擊dhcp，查看是否可以自動獲取到，能獲取到就說明配置完成了


測試lacp是否配置正確，隨便在一個交換機上關閉接口來模擬網絡測試

這邊看到接口已經模擬完成

使用pc來ping通測試，能夠看到一開始一直超時，以後恢復正常說明lacp配置正確（-t能夠一直ping ctrl+c是中止測試）

具體命令以下！

1.首先在三臺交換機建立vlan而且將各個接口加入到各自vlan，單數爲vlan10，複數爲vlan20

sys
un in en（關閉提示信息）
vlan batch 10 20（建立vlan）
exit
int e0/0/1
port link-type access
port default vlan 10
int e0/0/2
port link-type access
port default vlan 20

2.而後配置鏈路聚合和lacp，（之間是含有前後順序的，先進入eth-trunk組，配置中繼鏈路即容許全部vlan經過，而後配置lacp，最後再將接口加入到eth-trunk組中）

int Eth-Trunk 2
port link-type trunk
port trunk allow-pass vlan all
mode lacp-static
lacp timeout fast
lacp preempt enable
max active-linknumber 2
bpdu enable
q
interface Eth-Trunk 2
trunkport Ethernet 0/0/3 to 0/0/5
q

3.R1路由器的鏈路配置即單臂路由，（路由器的鏈路聚合配置首先加入eth-trunk組，使用命令（undo portswitch）讓路由二層變三層。以後再將接口捆綁起來，最後配置單臂路由）在AR1配置dhcp使pc機能夠自動得到IP地址
