单交换机划分VLAN实验

1、配置所有电脑的地址在192.168.1.0网段内，PC0为192.168.1.1，PC1为192.168.1.2 ，以此类推

2、检验所有PC是否可用互通，应该是可互通的。3、显示交换机的接口标签，在选项--首选项下面-总是显示接口标签4、在交换机上完成vlan创建和划分（先创建vlan，然后把交换机接口划分到vlan）Switch>enSwitch#conf t Switch(config)#vlan 10 创建vlan 10Switch(config-vlan)#name caiwu 命名为caiwuSwitch(config-vlan)#exit Switch(config)#vlan 20 创建vlan 20

Switch(config-vlan)#name jishu 命名为jishu

Switch(config-vlan)#exit Switch(config)#

Switch(config)#interface range f0/1-2 一次打开1和2两个接口

Switch(config-if-range)#switchport mode access 设置接口模式为accessSwitch(config-if-range)#switchport access vlan 10 接口划入vlan 10Switch(config-if-range)#exit Switch(config)#interface f0/3 Switch(config-if)#switchport mode access Switch(config-if)#switchport access vlan 20Switch(config-if)#exit Switch(config)#interface f0/4Switch(config-if)#switchport mode access Switch(config-if)#switchport access vlan 20Switch(config-if)#endSwitch#%SYS-5-CONFIG_I: Configured from console by console

跨交换机划分vlan

1、配置所有PC地址为同一个网段的192.168.1.02、检查网络是否互通3、一定要显示接口标签4、具体配置左边交换机配置Switch>enSwitch#conf tSwitch(config)#hostname sw1 sw1(config)#vlan 10 创建vlan 10sw1(config-vlan)#name caiwusw1(config-vlan)#vlan 20 创建vlan 20sw1(config-vlan)#nasw1(config-vlan)#name jishusw1(config-vlan)#exit sw1(config)#interface f0/2 这个接口要根据自己拓扑进行规划sw1(config-if)#switchport mode access sw1(config-if)#switchport access vlan 20 把接口划入vlan20sw1(config-if)#sw1(config-if)#interface f0/3sw1(config-if)#switchport mode access sw1(config-if)#switchport access vlan 10 把接口划入vlan10sw1(config-if)#exitsw1(config-if)#interface f0/1 交换机互联接口，根据你的拓扑设置sw1(config-if)#switchport mode trunk sw1(config-if)#switchport trunk allowed vlan all 分别测试 允许所有vlan

sw1(config-if)#switchport trunk allowed vlan 20 允许vlan20通过
