比较全面的三层交换机配置实例(带命令解释哟!) ??? 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 172.16.8.1 172.16.8.2 //三层交换机名字Catalyst 3550-12T1对应的IP地址是172.16.8.1??? Service dhcp //提供DHCP服务??? ip routing //启用三层交换机上的路由模块 ??? Exit??? 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）??? Vlan 3 name vlan3??? Vlan 4 name vlan4??? Vlan 5 name vlan5??? Vlan 6 name vlan6??? Vlan 7 name vlan7??? Vlan 8 name vlan8??? Vlan 9 name vlan9??? Exit ??? interface Port-channel 1 //进入虚拟的以太通道组1??? switchport trunk encapsulation dot1q //给这个接口的trunk封装为802.1Q的帧格式??? switchport mode trunk //定义这个接口的工作模式为trunk??? switchport trunk allowed vlan all //在这个trunk上允许所有的vlan通过??? Interface gigabitethernet 0/1 //进入模块0上的吉比特以太口1??? switchport trunk encapsulation dotlq //给这个接口的trunk封装为802.1Q的帧格式??? switchport mode trunk //定义这个接口的工作模式为trunk??? switchport trunk allowed vlan all //在这个trunk上允许所有的vlan通过??? channel-group 1 mode on //把这个接口放到快速以太通道组1中??? Interface gigabitethernet 0/2 //同上??? switchport trunk encapsulation dotlq??? switchport mode trunk??? switchport trunk allowed vlan all??? channel-group 1 mode on ??? port-channel load-balance src-dst-ip //定义快速以太通道组的负载均衡方式（依*源和目的IP的方式）??? interface gigabitethernet 0/3 //进入模块0上的吉比特以太口3??? switchport trunk encapsulation dotlq //给trunk封装为802.1Q??? switchport mode trunk //定义这个接口的工作模式为trunk ??? switchport trunk allowed vlan all //允许所有vlan信息通过 ??? interface gigabitethernet 0/4 //同上??? switchport trunk encapsulation dotlq??? switchport mode trunk??? switchport trunk allowed vlan all ??? interface gigbitethernet 0/5 //同上??? switchport trunk encapsulation dotlq??? switchport mode trunk??? switchport trunk allowed vlan al
