Cisco 交换机端口呈琥珀色常亮

我的交换机上有一个端口显示常亮的琥珀色灯。我尝试关闭此端口，但它仍然显示常亮的琥珀色灯。此交换机对生产至关重要，因此，除非有适当的计划窗口，否则我无法重新启动它。

感谢您的任何帮助，您可以提供。

以下是我对端口的设置：

#sh run int gi1/0/31

  interface GigabitEthernet1/0/31
  switchport access vlan 144
  switchport mode access
  spanning-tree portfast

#sh int gi1/0/31 status

  Port      Name               Status       Vlan       Duplex  Speed Type

答案1

  • 检查错误禁用

    显示 int 状态 err-disable

  • 关闭端口，等待 10 秒，然后重新启动端口

    关机/*等待10秒*/不关机

  • 重新安装电缆

  • 使用笔记本电脑直接插入该端口，查看是否有任何变化。如果一切正常，则说明线路出现故障或配置错误。
