华为端口VLAN设置

1、华为交换机VLA N配置问题的背景以及技术原理描述，华为交换机VLA N设置分为以下几个部分，VLA N背景描述，VLAN技术原理，VLA N实现功能，VLAN配置过程等等。华为交换机VLA N背景描述:假设此交换机是宽带小区城域网络中的1台楼道交换机，住户PC1连接在交换机的 F0/5 口；住户PC2连接在交换机的 F0/15 口。现在实现各家各户的端口隔离。华为交换机VLA N技术原理:VLAN( Virtual Local Area Network)是指在一个物理网段内，进行逻辑的划分，划分成若干个虚拟局域网。VLAN最大的特点是不受物理位置的限制，可以灵活的划分。相同的VLAN可以互相

2、进行通信，不同的VLAN间的主机不可以直接进行通信，必须通过路由器才可以进行通信。华为交换机VLAN作用：可以限制广播流量的转播，广播数据包只在VLAN进行转播，不能转到其他的VLAN中。Port Vlan是实现Vlan的方式之一，Port Vlan 是利用交换机的端口进行VLAN的划分，一个端口只能属于一个VLAN.华为交换机VLA N实现功能：通过划分 PORT VLAN实现本端口隔离华为交换机VLAN实验设备：可网管交换机一台，PC机2台，直连线2条华为交换机VLAN配置过程：PC1与PC2不能PING通就为成功。swi tceSwitch# Cooifi gure terminalsw
