华为交换机配置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 r d 代 表 研 发 部 , m a r k e t 代 表 市 场 部 [ S W 1 ] v l a n 10 [ S W 1 − v l a n 10 ] d e s c r i p t i o n R d 代表研发部,market 代表市场部 [SW1]vlan 10 [SW1-vlan10]description R d代表研发部,market代表市场部[SW1]vlan10[SW1−vlan10]descriptionRD [SW1-vlan10]vlan 20 [SW1-vlan20]description Market

[SW2] [SW2]vlan 10 [SW2-vlan10]description R$D [SW2-vlan10]vlan 20 [SW2-vlan20]description Market

[SW3] [SW3]vlan 10 [SW3-vlan10]description R$D [SW3-vlan10]vlan 20 [SW3-vlan20]description Market

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 PC1>ping 10.1.1.3
