实验一vlan的创建与划分

五、实验过程（配置过程）：

1.同一个交换机上的vlan划分

创建虚拟局域网VLAN11和VLAN22

Switch>enable

Switch#config

Configuring from terminal, memory, or network [terminal]?

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)#hostname S1

S1(config)#vlan 22

S1(config-vlan)#name T22

S1(config-vlan)#exit

S1(config)# vlan 11

S1(config-vlan)#name T11

S1(config-vlan)#exit

S1(config)#exit

S1#

验证测试：验证虚拟局域网VLAN11和VLAN22已创建成功

六、实验总结：

 通过本次实验，可以发现，不管是只有一个交换机，还是跨交换机，只有在相同的局域网上pc机之间才能通信，不在同一个局域网的pc之间不能通信。
