五、实验过程（配置过程）：
1.同一个交换机上的vlan划分
首先建立一个交互机，选择2960的（点击长方体），然后建立四个pc机进行连接（闪电）。
步骤1：划分子网，在交换机switch0上创建虚拟局域网VLAN101和VLAN102并为局域网VLAN101和VLAN102分配端口
点击交换机然后点击CLI按提示输入代码
Switch>en
Switch#config t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#vlan 101
Switch(config-vlan)#name M101
Switch(config-vlan)#exit
Switch(config)#vlan 102
Switch(config-vlan)#name M102
Switch(config-vlan)#exit
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#switchport access vlan 101
Switch(config-if)#exit
Switch(config)#interface fastEthernet 0/2
Switch(config-if)#switchport access vlan 101
Switch(config-if)#exit
Switch(config)#interface fastEthernet 0/3
Switch(config-if)#switchport access vlan 102
Switch(config-if)#exit
Switch(config)#interface fastEthernet 0/4
Switch(config-if)#switchport access vlan 102
Switch(config-if)#exit
Switch(config)#exit
Switch#
%SYS-5-CONFIG_I: Configured from console by console
验证虚拟局域网VLAN101和VLAN102已创建成功且分配端口成功
Switch#show vlan
将pc0和pc3划分到虚拟网段vlan11，pc1和pc2划分到虚拟网段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
sl (config)#vlan 102
sl (config-vlan) #name M102
s1 (config-vlan) #exit
S1(config)#vlan 101
sl (config-vlan) #name Ml01
sl (config-vlan)#exit
sl (config)#
验证虚拟局域网VLAN11和VLAN22已创建成功：
s1#show vlan
检查4台pc之间的通信情况
给pc机配置ip端口（左击pc机后配置）
pc0: 192.168.101.3，连接端口F0/1
pc1: 192.168.101.4，连接端口F0/2
pc2: 192.168.101.5，连接端口F0/4
pc3: 192.168.101.6，连接端口F0/3
pc0 ping pc3
pc2 分别ping pc1和pc0
2.进行跨交换机的相同vlan之间的计算机和不同vlan之间的计算机的通信实验.
在S1上创建虚拟局域网VLAN11和VLAN22并为之分配端口：
Switch>en

S1(config-vlan)#exit
S1(config)#interface fastethernet 0/1
S1(config-if)#switchport access vlan 11
S1(config-if)#exit
S1(config)#exit
S1#

S1(config)#interface fastethernet 0/2
S1(config-if)#switchport access vlan 22
S1(config-if)#exit
S1(config)#exit

将S1的F0/7端口设置为trunk模式：
S1#config
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
S1(config)#interface fastethernet 0/7

S1(config)#exit
