网络部分：
方案一，若是每个2层只有一个vlan的话，首先，三层创建所需要的vlan，其次，给创建的vlan一个地址，即你的网关地址！然后，2层到三层的接口划入相应的vlan即可，2层无需作任何配置！
方案二，每个2层交换机有多个vlan，首先，三层创建所需要的vlan，其次，给创建的vlan一个地址，即你的网关地址！2层到3层的接口改为truck模式，二层创建和3层相对应的vlan，把主机连接到2层的接口划入相应的vlan！或使用VTP，3层server，2层client！
主机部分，若每个2层下面只有一台主机，一个vlan，建议使用方案一，否则使用方案2！
主机配与相应的IP地址，注意网关为3层vlan的地址即可！或者在三层配置DHCP服务····
可以做VTP服务，三层做Server，二层做Client，如果有需要，改成透明模式也可以。然后三层划分VLAN，下面二层会自动学习。也可以自己手动划分。
如果是思科设备，
先建立vlan全局模式下：
vlan 10
name vlan10(名称自己定义)
直接进入相应接口：
int range f0/1-5，进入0-5的快速以太口
sw m a
sw a vlan 10。
show vlan brief 可以查看端口的Vlan划分情况。
问题太模糊了，都是什么交换机啊？
