1.3 步骤

实现此案例需要按照如下步骤进行。

1）在每个交换机上，批量创建相同的 VLAN

  3. 1.  <Huawei>system-view     //进入系统模式
  4. 2.  \[Huawei\]sysname SWx//更改设备名称(x表示 1~8，10)
  6. 4.  \[SWx\]vlan batch  10 20 30 40 66 88

2）交换机之间的链路，配置为 Trunk，并允许所有的 VLAN 通过

  3. 1.  \[SW1\]port-group group-member gi0/0/11 gi0/0/12
  4. 2.  \[SW1-port-group\]port link-type trunk
  5. 3.  \[SW1-port-group\]port trunk allow-pass vlan all
  6. 4.  \[SW1-port-group\]quit
  7. 5.  \[SW2\]port-group group-member gi0/0/11 gi0/0/12
  8. 6.  \[SW2-port-group\]port link-type trunk
  9. 7.  \[SW2-port-group\]port trunk allow-pass vlan all
  10. 8.  \[SW2-port-group\]quit
