交换机Trunk端口配置

交换机Trunk端口配置Trunk端口的配置步骤如下:一组网需求：SwitchA与SwitchB用trunk互连，相同VLAN的PC之间可以互访，不同VLAN的PC之间禁止互访;PC1与PC2之间在不同VLAN,通过设置上层三层交换机SwitchB的VLAN接口10的IP地址为10.1.1.254/24,VLAN接口20的IP地址为20.1.1.254/24可以实现VLAN间的互访。二组网图：VLAN内互访，VLAN间禁访SwitchBSwitchASwitchBV10 V2010.1.1.1/2410.1.1.2/24V10 V10 V2010.1.1.1/2410.1.1.2/24V10 V20101■13/24 ^0-1-1-4/242•通过三层交换机实现VLAN间互访SwitchBPC2SwitchBPC2V10 V2D血1.1•畑 20.1.1.2/24三配置步骤：实现VLAN内互访VLAN间禁访配置过程SwitchA相关配置:1.仓U建（进入）VLAN10,将E0/1力口入至UVLAN102.[SwitchA]vlan104.[SwitchA-vlan10]portEthernet0/16.2.仓U建（进入）VLAN20,将E0/2力口入至UVLAN208.[SwitchA]vlan2010.[SwitchA-vlan20]portEthernet0/212.3.将端口G1/1配置为Trunk端口，并允许VLAN10和VLAN20通过14.[SwitchA]interfaceGigabitEthernet1/116.[SwitchA-GigabitEthernet1/1]portlink-typetrunk18.19.[SwitchA-GigabitEthernet1/1]porttrunkpermitvlan1020SwitchB相关配置:1.1.仓建（进入）VLAN10,将E0/10力口入至UVLAN101.[SwitchB]vlan10[SwitchB-vlan10]portEthernet0/102.仓U建（进入）VLAN20,将E0/20力口入至UVLAN20[SwitchB]vlan20[SwitchB-vlan20]portEthernet0/203•将端口G1/1配置为Trunk端口，并允许VLAN10和VLAN20通过[SwitchB]interfaceGigabitEthernet1/1[SwitchB-GigabitEthernet1/1]portlink-typetrunk[SwitchB-GigabitEthernet1/1]porttrunkpermitvlan1020通过三层交换机实现VLAN间互访的配置SwitchA相关配置：1.仓U建（进入）VLAN10,将E0/1力口入至UVLAN10[SwitchA]vlan10[SwitchA-vlan10]portEthernet0/12.仓U建（进入）VLAN20,将E0/2力口入至UVLAN20[SwitchA]vlan20[SwitchA-vlan20]portEthernet0/23•将端口G1/1配置为Trunk端口，并允许VLAN10和VLAN20通过[SwitchA]interfaceGigabitEthernet1/1[SwitchA-GigabitEthernet1/1]portlink-typetrunk[SwitchA-GigabitEthernet1/1]porttrunkpermitvlan1020SwitchB相关配置：1.1.创建VLAN102.3.[SwitchB]vlan104.5.2•设置VLAN10的虚接口地址6.7.[SwitchB]interfacevlan108.9.[SwitchB-int-vlan10]ipaddress10.1.1.254255.255.255.010.11.3.创建VLAN2012.13.[SwitchB]vlan2014.15.4•设置VLAN20的虚接口地址16.17.[SwitchB]interfacevlan2018.19.[SwitchB-int-vlan20]ipaddress20.1.1.254255.255.255.020.5.将端口G1/1配置为Trunk端口，并允许VLAN10和VLAN20通过22.[SwitchA]interfaceGigabitEthernet1/124.[SwitchA-GigabitEthernet1/1]portli
