VLAN 实验
一：实验要求
二：实验拓扑图
pc1和pc3在同一个网段，IP配置为：192.168.1.0
pc2/4/5/6在同一个网段，IP配置为：192.168.2.0
三：创建VLAN
四：对R1配置DHCP服务
首先开启全局dhcp服务，然后在对每个接口开启dhcp服务
开启全局dhcp服务
dhcp enable对接口g0/0/0配置IP并且启用，将他设置为vlan 3，4，5的服务器
然后配置池子v2
配置池子V3
结果是：
设置子接口0/0/0.1来配置vlan2的服务器
五：对交换机的配置
LSW1
接口e0/0/4为混杂接口，带v 2的标签，不带vlan 3 to 5的标签
接口e0/0/1为混杂接口模式，带有所有的标签
接口e0/0/2为接入模式因为要求配置为access接口，修改默认pvid为2。
接口e0/0/3为混杂模式，不允许所有vlan，pvid为4
结果是：
LSW２
ｅ0/0/１ 为接口模式，允许vlan 2 to 5 的标签
ｅ0/0/２ 为混杂接口模式，允许vlan 2 to 5 的标签
ｅ0/0/3 为接入接口模式，pvid为2
ｅ0/0/4 为混杂接口模式，pvid为4，不允许带vlan 1 to 4 的标签
结果是：
LSW3
ｅ0/0/1 为混杂接口模式，允许带vlan2 to 5 所有标签
ｅ0/0/２ 为混杂接口模式，pvid为4，不允许带vlan 2 to 4 标签
ｅ0/0/３ 为混杂接口模式，pvid为5，不允许带vlan 2 to 3 5 标签
结果是：
六：最后结果
PC1 可以ping 2/4/5/6
