Cisco PT 案例四：VLAN（Access模式实践）

环境

• Cisco Packet Tracer 5.3
• Windows 10

操作

操作：按照如图所示连接拓扑图

实验步骤

1. 创建VLAN 2和VLAN 3
2. 将部门PC对应端口划分到相应的VLAN中

PC设置

192.168.1.2        //PC0
192.168.1.3        //PC1
192.168.1.4        //PC2
192.168.1.5        //R0
//子网掩码和网关
255.255.255.0
192.168.1.1

Switch0配置

Switch>en                        // 进入特权模式
Switch#conf t                // 进入全局配置模式命令缩写
Enter configuration commands, one per line.  End with CNTL/Z.
Switch(config)#vlan 2
Switch(config-vlan)#exit
Switch(config)#vlan 3
Switch(config-vlan)#exit
Switch(config)#inter f0/1
Switch(config-if)#switchport access vlan 2
Switch(config-if)#exit
Switch(config)#inter f0/2
