新华三VLAN-TRUNK组网实验
实验 1 二层业务隔离（VLAN 与 Trunk）
1.1.1组网拓扑
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
