篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了华为 eNSP—交换机配置（三层）相关的知识，希望对你有一定的参考价值。

1 先创建如图 的网络拓扑图

1.1 需要设备：

	交换机：S5700（1个）、S3700（2个）、
	终端：PC（8个）

1.2 按照接口连线：

				所有接口已显示

2 配置 交换机

2.1 LSW6：

关闭配置提示：< Huawei > undo terminal monitor

命令行如下（ LSW6 ）：
The device is running!

<Huawei>system-view 
Enter system view, return user view with Ctrl+Z.
[Huawei]vlan 10
[Huawei-vlan10]vlan 20
[Huawei-vlan20]vlan 30
[Huawei-vlan30]vlan 40
[Huawei-vlan40]quit
[Huawei]int g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[Huawei-GigabitEthernet0/0/1]dis this
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 2 to 4094
#
return
[Huawei-GigabitEthernet0/0/1]int g0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type trunk
[Huawei-GigabitEthernet0/0/2]port trunk allow-pass vlan all
[Huawei-GigabitEthernet0/0/2]q
[Huawei]int vlanif 10
[Huawei-Vlanif10]ip addr 192.14.10.1 24

[Huawei-Vlanif10]int vlanif 20
[Huawei-Vlanif20]ip addr 192.14.20.1 24
[Huawei-Vlanif20]int vlanif 30
[Huawei-Vlanif30]ip addr 192.14.30.1 24
[Huawei-Vlanif30]int vlanif 40
[Huawei-Vlanif40]ip addr 192.14.40.1 24
[Huawei-Vlanif40]q
[Huawei]q
<Huawei>save
The current configuration will be written to the device.
Are you sure to continue?[Y/N]Y
Info: Please input the file name ( *.cfg, *.zip ) [vrpcfg.zip]:
Mar  8 2022 21:43:37-08:00 Huawei %%01CFM/4/SAVE(l)[12]:The user chose Y when de
ciding whether to save the configuration to the device.
Now saving the current configuration to the slot 0.
Save the configuration successfully.
<Huawei>

导出设备配置并保存（重点：不保存，下次打开就会出现丢失配置的情况）

2.2 LSW4、LSW5：

	  两者命令行一样（注意接口变一下）
代码如下（ LSW4 ）：
The device is running!

<Huawei>system-view 
Enter system view, return user view with Ctrl+Z.
[Huawei]vlan 10
[Huawei-vlan10]vlan 20
[Huawei-vlan20]vlan 30

3 配置 终端（PC）

	 【XX：可自己随意设置】
	 VLAN 10: 
	 			PC1（192.XX.10.2）
	 			PC2（192.XX.10.3）


	VLAN 20: 
				PC3（192.XX.20.2）
				PC4（192.XX.20.3）


	VLAN 30: 
	 			PC4（192.XX.30.2）
	 			PC5（192.XX.30.3）
	VLAN 40: 
	 			PC6（192.XX.40.2）
	 			PC7（192.XX.40.3）

4 验证 （ping命令）

	此处用 vlan 30 中的 PC6（192.XX.40.2） 
		分别 ping vlan 10 和 vlan 40
			结果 ping 通 配置完成！

5 补充 （部分命令意义）

如果网关设置错了 先删除再配置  
			可用命令 undo ip addr


导出设备配置并保存（重点：不保存，下次打开就会出现丢失配置的情况）

	小编就曾因为没有保存导出配置 
				而重新配置过好几次 引以为戒啊！！！

最后的最后 如有问题 欢迎各位指正！！！
