eNSP模拟器Trunk端口测试

打开eNSP模拟器，添加两台交换机和四台电脑，每台交换机连接两台电脑，连接线使用接口如下图

启动LSW1交换机，进入CLI控制台配置命令如下：

system-view

Enter system view, return user view with Ctrl+Z.

[Huawei]undo info-center enable #关闭系统信息提示服务。

Info: Information center is disabled.

[Huawei]vlan 2 #创建vlan 2

[Huawei-vlan2]inter Eth 0/0/1 #进入端口分配给vlan 2

[Huawei-Ethernet0/0/1]port link-type access

[Huawei-Ethernet0/0/1]port default vlan 2

[Huawei-Ethernet0/0/1]vlan 3 #创建vlan 3

[Huawei-vlan3] inter eth 0/0/2

[Huawei-Ethernet0/0/2]port link-type access

[Huawei-Ethernet0/0/2]port default vlan 3

[Huawei-Ethernet0/0/2]

LSW1交换机配置GE 0/0/1为trunk端口，命令如下：

[Huawei]inter GigabitEthernet 0/0/1

[Huawei-GigabitEthernet0/0/1]port link-type trunk

[Huawei-GigabitEthernet0/0/1]port trunk permit vlan all

^

Error: Unrecognized command found at '^' position.

[Huawei-GigabitEthernet0/0/1]port trunk p

[Huawei-GigabitEthernet0/0/1]port trunk pe

[Huawei-GigabitEthernet0/0/1]port trunk pe

[Huawei-GigabitEthernet0/0/1]port trunk pe

[Huawei-GigabitEthernet0/0/1]port trunk a

[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan all

[Huawei-GigabitEthernet0/0/1]

注意port trunk permit vlan all 和port trunk allow-pass vlan all命令等价，只是不同型号要使用对应的命令，都是此端口允许所有vlan通过

启动LSW2交换机，进入CLI控制台配置命令如下：

system-view

Enter system view, return user view with Ctrl+Z.

[Huawei]undo info-center enable

Info: Information center is disabled.

[Huawei]vlan 2

[Huawei-vlan2]inter eth 0/0/1

[Huawei-Ethernet0/0/1]port link-type access

[Huawei-Ethernet0/0/1]port default vlan 2

[Huawei-Ethernet0/0/1]vlan 3

[Huawei-vlan3]inter eth 0/0/2

[Huawei-Ethernet0/0/2]port link-type access

[Huawei-Ethernet0/0/2]port default vlan 3

[Huawei-Ethernet0/0/2]inter g

[Huawei-Ethernet0/0/2]inter gi

[Huawei-Ethernet0/0/2]quit

[Huawei]inter g

[Huawei]inter GigabitEthernet 0/0/1

[Huawei-GigabitEthernet0/0/1]port link-type trunk

[Huawei-GigabitEthernet0/0/1]port trunk a

[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan all

解释见上两步LSW1配置

右键PC1设置，设置ip地址及子网掩码如下图

右键PC2设置，设置ip地址及子网掩码如下图

右键PC3设置，设置ip地址及子网掩码如下图

右键PC4设置，设置ip地址及子网掩码如下图

启动四台电脑后，在PC1命令行

ping 10.5.1.2 网络通，证明LSW1和LSW2通过trunk口连接正常
