**实验 1 二层业务隔离（VLAN 与 Trunk）**

1.1.1组网拓扑

![5a798c22a02b27fa4526df0993b21d87.png][]

1.1.2. 实验任务

(1) 实现同一 Vlan 内的主机互通，不同一 Vlan 间的主机隔离。  
VLAN 10：PC1、PC3；  
VLAN 20：PC2、PC4；

(2) 广播域与连通性分析  
分析 PC1、PC2、PC3、PC4、PC5 发出广播帧的到达范围。

1.1.3. 基本信息配置

system-view  
\[H3C\]hostname SW1

1.1.4. VLAN配置

**SW1配置**  
\[SW1\]vlan 10 // 创建 vlan 10  
\[SW1-vlan10\]port GigabitEthernet 1/0/2 // 将接口加入 vlan 10  
\[SW1\]interface GigabitEthernet 1/0/2 // 进入接口 1/0/2  
\[SW1-GigabitEthernet1/0/2\]port link-type access // 配置为 access 模式

\[SW1\]interface GigabitEthernet 1/0/3 // 创建 vlan 20  
\[SW1\]interface GigabitEthernet 1/0/3 // 进入接口 1/0/3  
\[SW1-GigabitEthernet1/0/2\]port link-type access // 配置为 access 模式

**SW2配置**  
\[SW2\]vlan 10 // 创建 vlan 10  
\[SW2-vlan10\]port GigabitEthernet 1/0/2 // 将接口加入 vlan 10  
\[SW2\]interface GigabitEthernet 1/0/2 // 进入接口 1/0/2  
\[SW2-GigabitEthernet1/0/2\]port link-type access // 配置为 access 模式  
\[SW2\]vlan 20 // 创建 vlan 20  
\[SW2\]interface GigabitEthernet 1/0/3 // 进入接口 1/0/3  
\[SW2-GigabitEthernet1/0/3\]port link-type access // 配置为 access 模式

**查看接口信息操作**  
\[SW1\]display interface g1/0/2 // 查看接口信息
