    MX2020 MIC 故障排除

    Problem

    MIC LED 亮起为红色表示 MIC 存在问题。

    Solution

    要排除 MIC 的故障:

    1. 观察 MIC 面板上的 LED,以检查 MIC 上每个端口的状态。 有关不同 MIC 上的 LED 状态的含义的信息。 有关更多信息,请参阅 MX 系列 3D 通用边缘路由器线卡指南 PDF Document
    2. 检查 MIC 的状态,方法是发出 show chassis fpc pic-status CLI 命令。 MPC 中的 MIC 插槽从顶部至底部依次标记为 PIC 0/1PIC 2/3
