实现不同vlan间PC不可访问,不同vlan的PC均可访问服务器的效果,具体要求如下
- 在交换机中创建相关vlan
- 修改端口模式
- 修改端口允许通过的数据帧
- 结果验证,vlan5与vlan10的pc不可互通,但与服务器互通
方案
使用eNSP搭建实验环境
步骤
配置第一台交换机
ps:交换机1与pc的接口为0/0/1,与pc的接口为0/0/2,交换机与交换机之间的接口为0/0/3,交换机2与pc3的接口为0/0/1
[SW1]vlan batch 5 10 50 //创建5 10 50的vlan
[SW1]interface Ethernet0/0/1 //进入接口0/0/1
[SW1-Ethernet0/0/1]port hybrid untagged vlan 5 50 //此端口发送vlan5 10 50数据帧时不带标签
[SW1-Ethernet0/0/1]port hybrid pvid vlan 5 //把端口加入vlan5
[SW1]interface Ethernet0/0/2 //进入接口0/0/2
[SW1-Ethernet0/0/2]port hybrid untagged vlan 10 50 //此端口发送vlan10 50数据帧时不带标签
[SW1-Ethernet0/0/2]port hybrid pvid vlan 10 //把端口接入vlan10
[SW1]interface Ethernet0/0/3 //进入接口0/0/3
[SW1-Ethernet0/0/3]port hybrid tagged vlan 5 10 50 //此端口发送vlan 5 10 50数据帧时加标签
[SW1]dis vlan //查看路由表
The total number of vlans is : 4
