华为交换机配置trunk接口
配置Trunk接口
trunk端口一般用于交换机之间连接的端口，trunk端口可以属于多个vlan，可以接受发发送多个vlan的报文。
本次的实验如下图：
模拟两天办公区怎么互信通信，切互不影响，PC1与PC3是同网段，PC2与PC4是相同网段

以下是基础网络配置
[SW1]interface Ethernet 0/0/2
[SW1-Ethernet0/0/2]port link-type access
[SW1-Ethernet0/0/2]port default vlan 10
[SW1]interface Ethernet 0/0/3
[SW1-Ethernet0/0/2]port link-type access
[SW1-Ethernet0/0/2]port default vlan 20
[SW2]interface Ethernet 0/0/3
[SW2-Ethernet0/0/3]port link-type access
[SW2-Ethernet0/0/3]port default vlan 10
[SW2]interface Ethernet 0/0/4
[SW2-Ethernet0/0/4]port link-type access
[SW2-Ethernet0/0/4]port default vlan 20
接下来配置trunk接口
[SW1]interface Ethernet 0/0/1
[SW1-Ethernet0/0/1]port link-type trunk
[SW1-Ethernet0/0/1]port trunk allow-pass vlan 10 20
[SW2]interface Ethernet 0/0/2
[SW2-Ethernet0/0/2]port link-type trunk
[SW2-Ethernet0/0/2]port trunk allow-pass vlan 10 20
[SW3]interface GigabitEthernet 0/0/1
[SW3-GigabitEthernet0/0/1]port link-type trunk
[SW3-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[SW3]interface GigabitEthernet 0/0/2
[SW3-GigabitEthernet0/0/2]port link-type trunk
[SW3-GigabitEthernet0/0/2]port trunk allow-pass vlan all
配置完成后PC1 ping PC3
