由于缆线故障、导致Brocade交换机端口盖板

适用场景

Brocade 交换机上的端口

问题描述

• 在switchshow下、交换机端口状态为联机

/fabos/bin/switchshow :

• 在porterrshow下、 link failureloss sync enc_out, crc err, crc g_eof, c3timeout Tx, pcsuncorr  系统会报告多个和错误以及其他介质错误、例如和错误。

• sfpshow 报告Rx和Tx 值处于最佳范围。

RX Power:   1.4    dBm (1365.3uW) 
TX Power:   -0.4   dBm (910.2 uW) 

• sfpshow 报告Rx值过低。

RX Power:    -15.1   dBm (30.7 uW)
TX Power:    -1.7    dBm (678.9 uW)

• portshow 输出确认端口为联机且处于In-Sync状态、 LR_IN大于OLS_OUT、这表示问题描述是switchport的外部端口。
