华为 eNSP—交换机配置（三层）

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.

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 ）：

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！！！
