Trunk端口的配置步骤如下:
一 组网需求:
1.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;
2.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:
1.VLAN内互访,VLAN间禁访
2.通过三层交换机实现VLAN间互访
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.创建(进入)VLAN10,将E0/1加入到VLAN10
- [SwitchA]vlan 10
- [SwitchA-vlan10]port Ethernet 0/1
- 2.创建(进入)VLAN20,将E0/2加入到VLAN20
- [SwitchA]vlan 20
- [SwitchA-vlan20]port Ethernet 0/2
- 3.将端口G1/1配置为Trunk端口,并允许VLAN10和VLAN20通过
- [SwitchA]interface GigabitEthernet 1/1
- [SwitchA-GigabitEthernet1/1]port link-type trunk
- [SwitchA-GigabitEthernet1/1]port trunk permit vlan 10 20
SwitchB相关配置:
- 1.创建(进入)VLAN10,将E0/10加入到VLAN10
- [SwitchB]vlan 10
- [SwitchB-vlan10]port Ethernet 0/10
- 2.创建(进入)VLAN20,将E0/20加入到VLAN20
- [SwitchB]vlan 20
- [SwitchB-vlan20]port Ethernet 0/20
- 3.将端口G1/1配置为Trunk端口,并允许VLAN10和VLAN20通过 [SwitchB]interface GigabitEthernet 1/1
- [SwitchB-GigabitEthernet1/1]port link-type trunk [SwitchB-GigabitEthernet1/1]port trunk permit vlan 10 20
- 通过三层交换机实现VLAN间互访的配置
SwitchA相关配置:
- 1.创建(进入)VLAN10,将E0/1加入到VLAN10
- [SwitchA]vlan 10
- [SwitchA-vlan10]port Ethernet 0/1
- 2.创建(进入)VLAN20,将E0/2加入到VLAN20
- [SwitchA]vlan 20
- [SwitchA-vlan20]port Ethernet 0/2
- 3.将端口G1/1配置为Trunk端口,并允许VLAN10和VLAN20通过 [SwitchA]interface GigabitEthernet 1/1
- [SwitchA-GigabitEthernet1/1]port link-type trunk [SwitchA-GigabitEthernet1/1]port trunk permit vlan 10 20
SwitchB相关配置:
- 1.创建VLAN10
- [SwitchB]vlan 10
- 2.设置VLAN10的虚接口地址
- [SwitchB]interface vlan 10
- [SwitchB-int-vlan10]ip address 10.1.1.254 255.255.255.0
- 3.创建VLAN20
- [SwitchB]vlan 20
- 4.设置VLAN20的虚接口地址
- [SwitchB]interface vlan 20
- [SwitchB-int-vlan20]ip address 20.1.1.254 255.255.255.0
- 5.将端口G1/1配置为Trunk端口,并允许VLAN10和VLAN20通过
- [SwitchA]interface GigabitEthernet 1/1
- [SwitchA-GigabitEthernet1/1]port link-type trunk
- [SwitchA-GigabitEthernet1/1]port trunk permit vlan 10 20
VLAN中Trunk口的配置就结束了,希望大家已经掌握。
