通过华为eNSP模拟器，来进行华为eth-trunk实验以及延申实验
1、不同vlan间通信，实验拓扑图如下:
环境:两台华为交换机，六台PC，规划配置vlan 10,vlan 20
SW01交换机所连PC配置:
PC1:192.168.10.10/24 vlan 10
PC2:192.168.10.20/24 vlan 10
PC3:192.168.20.10/24 vlan 20
PC4:192.168.20.20/24 vlan 20
SW02交换机所连PC配置:
PC5192.168.10.30/24 vlan 10
PC6:192.168.20.30/24 vlan 20
1、首先PC配置好IP后，做个测试，PC1是否可以Ping通PC5
测试结果是通的，如图
2、配置交换机的vlan
SW01：
<Huawei>system-view
[Huawei]sysname SW01
[SW01]vlan batch 10 20
[SW01]display vlan #查看一下vlan，目前vlan还未配置接口下
[SW01]interface GigabitEthernet 0/0/1
[SW01-GigabitEthernet0/0/1]port link-type access
[SW01-GigabitEthernet0/0/1]port default vlan 10
[SW01-GigabitEthernet0/0/1]display this #查看接口下配置
[SW01]interface GigabitEthernet 0/0/2
[SW01-GigabitEthernet0/0/2]port link-type access
[SW01-GigabitEthernet0/0/2]port default vlan 10
[SW01]interface GigabitEthernet 0/0/3
[SW01-GigabitEthernet0/0/3]port link-type access
[SW01-GigabitEthernet0/0/3]port default vlan 20
其他与PC相连的接口都是类似配置，就不赘述了
这时再查看一下vlan，此时vlan已配置到接口下
SW02交换机也是类似配置，查看一下vlan配置
这时再看下PC1是否可以Ping通PC5，此时是不通的
此时需要配置交换机相连的接口，配置好trunk
[SW01]interface GigabitEthernet 0/0/24
[SW01-GigabitEthernet0/0/24]port link-type trunk
[SW01-GigabitEthernet0/0/24]port trunk allow-pass vlan 10 20
[SW02]interface GigabitEthernet 0/0/24
[SW02-GigabitEthernet0/0/24]port link-type trunk
[SW02-GigabitEthernet0/0/24]port trunk allow-pass vlan 10 20
此时看PC1ping测试PC5,如图，通了
3、接下来做eth-trunk聚合链路的实验，实验拓扑如图
首先将交换机相连的24口下的trunk先删除
[SW01]interface GigabitEthernet 0/0/24
[SW01-GigabitEthernet0/0/24]undo port trunk allow-pass vlan 10 20
[SW01-GigabitEthernet0/0/24]undo port link-type
[SW02]interface GigabitEthernet 0/0/24
[SW02-GigabitEthernet0/0/24]undo port trunk allow-pass vlan 10 20
[SW02-GigabitEthernet0/0/24]undo port link-type
接下来配置编号为1的eth-trunk端口(eth-trunk1)
[SW01]interface Eth-Trunk 1
[SW01-Eth-Trunk1]mode lacp-static
[SW01-Eth-Trunk1]trunkport GigabitEthernet 0/0/23 to 0/0/24 #将23口和24口加入到eth-trunk1端口
[SW01-Eth-Trunk1]port link-type trunk
[SW01-Eth-Trunk1]port trunk allow-pass vlan 10 20
[SW01]display interface Eth-Trunk1 #查看一下eth-trunk1
[SW02]interface Eth-Trunk 1
[SW02-Eth-Trunk1]mode lacp-static
[SW02-Eth-Trunk1]trunkport GigabitEthernet 0/0/23 to 0/0/24
[SW02-Eth-Trunk1]port link-type trunk
[SW02-Eth-Trunk1]port trunk allow-pass vlan 10 20
验证一下是否配置成功，如图，通了
验证一下，将24口down一下看看
[SW01-GigabitEthernet0/0/24]shutdown
出现上图情况，是因为stp没有关掉导致的
这时将stp关掉
[SW01]stp disable
[SW02]stp disable
再来进行测试
[SW01-GigabitEthernet0/0/24]shutdown
如图，没有丢包了
