思科模拟器三层交换机配置实验

连接设配

注：两台笔记本用于配置两台交换机

pc_name	ip	mask	rlation_f
laptop2	192.168.3.100	192.168.3.1	f0/4
pc0	192.168.1.100	192.168.1.1	f0/1
pc1	192.168.2.100	192.168.2.1	f0/2

配置3960

Switch(config)#vlan 10          //创建vlan 10
Switch(config-vlan)#exit
Switch(config)#vlan 20
Switch(config-vlan)#exit
Switch(config)#int f0/1        //进入f0/1 端口
Switch(config-if)#switchport mode access   配置端口模式为access ,accesss模式只允许一个vlan通过，trunk 可允许多个
Switch(config-if)#switchport access vlan 10  //允许vlan 10 通过
Switch(config-if)#exit
Switch(config)#int f0/2
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 20
Switch(config-if)#exit
Switch(config)#vlan 30
Switch(config-vlan)#exit
Switch(config)#int f0/4
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 30
Switch(config-if)#

配置3960与3560连接的端口

Switch(config)#int f0/3
Switch(config-if)#switchport mode trunk

配置3560

Switch(config)#vlan 10   //创建vlan 10
Switch(config-vlan)#exit
Switch(config)#vlan 20
Switch(config-vlan)#exit
Switch(config)#int vlan 10  //进入vlan 10
Switch(config-if)#  //下面两行是系统提示
%LINK-5-CHANGED: Interface Vlan10, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan10, changed state to up

Switch(config-if)#ip address 192.168.1.1 255.255.255.0  //配置vlan IP 地址，对应pc上的网关
Switch(config-if)#no shutdown   //启动端口
Switch(config-if)#exit
Switch(config)#int vlan 20
Switch(config-if)#

Switch(config)#int f0/1        //进入与3960交换机连接的端口，并配置成trunk模式
Switch(config-if)#switchport mode trunk
Command rejected: An interface whose trunk encapsulation is "Auto" can not be configured to "trunk" mode.
