Brocade交换机端口脱机并处于"无灯"状态、Rx/Tx电源显示为-INF

适用场景

Brocade交换机

问题描述

• 交换机端口  在  F端口 或ISL端口的switchshow 输出下显示No_light ：

Index Port Address Media Speed  State    Proto
==============================================
   5   5   0xx500   id     4G   No_Light    FC Disabled  

• porterrshow 表示链路故障和丢失SIG错误

• 两个交换机上的ISL端口均出现闪烁。
• 对于ISL端口终端设备交换机、可以验证Rx和Tx值以进行故障隔离。
• 交换机上的错误转储可能会记录以下内容：  2024/11/16-12:18:16 (IST), [PORT-1003], 126304, FID 128 | PORT 0/31, WARNING, Switch2, Port 31 Faulted because of many Link Failures.
