计算机网络实验

 1.创建虚拟局域网VLAN10和VLAN20

Switch>enable

Switch#conf t

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

Switch(config)#vlan 10

Switch(config-vlan)#name DWQ

Switch(config-vlan)#vlan 20

Switch(config-vlan)#name CJ

Switch(config-vlan)#exit

为局域网VLAN11和VLAN22分配端口

Switch(config)#interface fa0/1

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 10

Switch(config-if)#interface fa0/2

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 10

Switch(config-if)#interface fa0/3

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 20

Switch(config-if)#interface fa0/4

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 20

Switch(config-if)#exit

Switch(config)#exit

Switch#

%SYS-5-CONFIG_I: Configured from console by console

 

验证测试：验证为VLAN11和VLAN22分配端口成功

Switch#vlan database

% Warning: It is recommended to configure VLAN from config mode,

as VLAN database mode is being deprecated. Please consult user

documentation for configuring VTP/VLAN in config mode.

 

Switch(vlan)#vlan 10 name DWQ

VLAN 10 added:

Name: DWQ

Switch(vlan)#vlan 20 name CJ

VLAN 20 added:

Name: CJ

Switch(vlan)#exit

APPLY completed.

Switch(config)#interface fa0/5

Switch(config-if)#switchport mode trunk

将交换机1的fa0/5端口设置为trunk模式

Switch#conf t

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

Switch(config)#interface fa0/5

Switch(config-if)#switchport mode trunk

五、实验总结：

通过这个实验中我学会了创建虚拟局域网vlan，并配置端口。并且将交换机和PC连接起来。而且认识到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。通过实验熟悉了操作流程。
