发我以前配置过的，你自己研究一下

三层交换机是不是经常让你机器不好使，看看下面的三层交换机配置文章，一切问题都能解决。本文详细介绍实例讲解：全面的三层交换机配置比较全面的三层交换机配置实例，带命令解释哟！

三层交换机配置：

Enable //进入私有模式

Configure terminal //进入全局模式

service password-encryption //对密码进行加密

hostname Catalyst 3550-12T1 //给三层交换机定义名称

enable password 123456 //enable密码

Enable secret 654321 //enable的加密密码(应该是乱码而不是654321这样)

Ip subnet-zero //允许使用全0子网(默认都是打开的)

Ip name-server 1721681 1721682 //三层交换机名字Catalyst 3550-12T1对应的IP地址是1721681

Service dhcp //提供DHCP服务

ip routing //启用三层交换机上的路由模块

Exit

三层交换机配置：

Vtp mode server //定义VTP工作模式为sever模式

Vtp domain centervtp //定义VTP域的名称为centervtp

Vlan 2 name vlan2 //定义vlan并给vlan取名(如果不取名的话，vlan2的名字应该是vlan002)
