1 案例1：划分VLAN

1.1 问题

在交换机上创建以下VLAN，按照拓扑图-1将端口加入到指定的VLAN并配置服务器IP地址，实现同VLAN主机的通信

图-1

1.2 步骤

实现此案例需要按照如下步骤进行

步骤一：创建vlan，并将接口加入

由于默认情况下所有接口都在VLAN1中，且VLAN1默认就存在，所以只需要配置VLAN2和VLAN3即可

  1. <Huawei>system-view 
  2. [Huawei]vlan batch 2 3            //创建VLAN2、3
  3. [Huawei]port-group 1
  4. [Huawei-port-group-1]group-member Ethernet0/0/3 Ethernet0/0/4
  5. [Huawei-port-group-1]port link-type access 
  6. [Huawei-port-group-1]port default vlan 2                        
  7. [Huawei-port-group-1]quit
  8. [Huawei]port-group 2
  9. [Huawei-port-group-2]group-member Ethernet0/0/5 Ethernet0/0/6
  10. [Huawei-port-group-2]port link-type access 
  11. [Huawei-port-group-2]port default vlan 3    

2 案例2：多交换机VLAN的划分

2.1 问题

通过配置交换机实现图-2中的同VLAN主机互通

  3. [Huawei-Ethernet0/0/7] port default vlan 3

2）S2配置

  1. <Huawei>system-view 
  2. [Huawei]vlan 3            //创建VLAN3

  5. [Huawei-port-group-1]port link-type access 
  6. [Huawei-port-group-1]port default vlan 3    

3 案例3：配置trunk中继链路

  3. [Huawei]interface Ethernet0/0/7
  4. [Huawei-Ethernet0/0/7]port default vlan 1
  5. [Huawei-Ethernet0/0/7]port link-type trunk
  6. [Huawei-Ethernet0/0/1]port trunk allow-pass vlan all

2）S2配置

  1. <Huawei>system-view 
  2. [Huawei]vlan 2         //创建VLAN2
  3. [Huawei]port-group 1
  4. [Huawei-port-group-1]group-member Ethernet0/0/3 Ethernet0/0/4
  5. [Huawei-port-group-1]port link-type access 
  6. [Huawei-port-group-1]port default vlan 2                        
  7. [Huawei]interface Ethernet0/0/7
  8. [Huawei-Ethernet0/0/7]port default vlan 1
  9. [Huawei-Ethernet0/0/7]port link-type trunk
  10. [Huawei-Ethernet0/0/1]port trunk allow-pass vlan all

4 案例4：链路聚合配置

4.1 问题

参照图-4将两台交换机的f0/1-f0/2接口互联，并实现高可用

图-4

4.2 步骤

步骤一：创建链路聚合接口，并捆绑物理接口

1）S1配置

  1. [Huawei]interface Eth-trunk 1
  2. [Huawei- Eth-trunk1]trunkport ethernet 0/0/1  0/0/2
  3.  
  4. 如果接口被改动过，则需要恢复默认配置
  5. [Huawei] clear configuration interface Ethernet0/0/1
