eNSP下园区网综合实验分步配置（1）Eth-Trunk、Vlan、Trunk

链路聚合（Eth-Trunk）：

接入交换机SW6与汇聚交换机SW3

SW6（接入）：
<Huawei>system-view
[Huawei]sysname JieRu-SW6
[JieRu-SW6]undo info-center enable //关闭日志
[JieRu-SW6]interface Eth-Trunk 1
[JieRu-SW6-Eth-Trunk1]mode lacp-static 
[JieRu-SW6-Eth-Trunk1]trunkport GigabitEthernet 0/0/1
[JieRu-SW6-Eth-Trunk1]trunkport GigabitEthernet 0/0/2

SW3（汇聚）：
<Huawei>system-view
[Huawei]sysname HuiJu-SW3
[HuiJu-SW3]undo info-center enable
[HuiJu-SW3]int Eth-Trunk 1
[HuiJu-SW3-Eth-Trunk1]mode lacp-static 
[HuiJu-SW3-Eth-Trunk1]trunkport GigabitEthernet 0/0/2
[HuiJu-SW3-Eth-Trunk1]trunkport GigabitEthernet 0/0/3

核心交换机SW1、SW2

SW1（核心）：
<Huawei>sys
[Huawei]sysname HeXin-SW1
[HeXin-SW1]undo info-center enable
[HeXin-SW1]interface Eth-Trunk 2
[HeXin-SW1-Eth-Trunk2]mode lacp-static 
[HeXin-SW1-Eth-Trunk2]trunkport GigabitEthernet 0/0/2
[HeXin-SW1-Eth-Trunk2]trunkport GigabitEthernet 0/0/3

SW2（核心）：

[HeXin-SW2-Eth-Trunk2]trunkport GigabitEthernet 0/0/1
[HeXin-SW2-Eth-Trunk2]trunkport GigabitEthernet 0/0/2

可以用如下命令查看聚合端口：

[HeXin-SW1]display eth-trunk 2
//正常情况下可以看到两个端口被选择

当需要将某个交换机端口由trunk改为access，可以：

undo port default vlan xx
或
undo port  trunk allow-pass vlan all

而后
undo port link-type

裁剪vlan的目的在于减小广播域范围。
