32 华三vlan案例+STP

1 开启STP

显示根桥信息

查看stp中的接口角色

查看设备的根桥ID 最小的值是根网桥

原则一 网络初始化时，网络中所有的STP设备都认为自己是“根桥”，根桥ID为自身的设备ID。通过交换BPDU，设备之间比较根桥ID，网络中根桥ID最小的设备被选为根桥。

SW4 优先机 改为0

3 在同一网段PC机可以互通 ping 172.168.13.254/24 测试结果

问题来了 为什么能通？

这是一个显示命令，用于查看交换机SW1-B上的所有VLAN配置信息。

  • VLAN ID: 1 表示该VLAN的唯一标识为1。
  • VLAN type: Static 表示该VLAN是静态VLAN，由管理员手动配置的。
  • Route interface: Not configured 表示该VLAN没有配置路由接口，无法进行跨VLAN通信。
  • Description: VLAN 0001 表示该VLAN的描述为"VLAN 0001"。
  • Name: VLAN 0001 表示该VLAN的名称也为"VLAN 0001"。
  • Tagged ports: None 表示该VLAN上没有配置Trunk端口，不能传递多个VLAN的数据。
  • Untagged ports: FortyGigE1/0/53 表示该VLAN上配置了一个Untagged端口，即FortyGigE1/0/53端口，该端口上的数据将属于该VLAN，不需要打上VLAN标签。

4   vlan的创建

  • Redirect it to a file - 这个选项允许用户将命令的输出重定向到一个文件中，而不是在终端上显示。
  • Redirect it to a file in append mode - 这个选项类似于上一个选项，但它会将输出追加到现有文件的末尾，而不是覆盖文件。
  • INTEGER<1-4094> - 这是一个参数，用户可以指定一个整数（1到4094之间），来显示特定VLAN的配置信息。
  • all - 显示所有VLAN的配置信息。
  • brief - 显示所有VLAN的简要信息。
  • dynamic - 显示动态VLAN的配置信息。
  • mapping - 显示VLAN映射信息，这可能包括VLAN ID与端口之间的映射关系。
  • reserved - 显示保留的VLAN配置信息。
  • static - 显示静态VLAN的配置信息。
  • | - 这个符号通常用于管道操作，允许用户将命令的输出作为另一个命令的输入。
