Brocade 交换机上的端口

问题描述

  • 交换机端口状态为online under switchshow

/fabos/bin/switchshow :

129   4   33   708100   id   N32    Online    FC  F-Port  10:00:00:10:9b:xx:xx:xx

 

  • 在porterrshow 下，  报告多个link failure 和loss sync 错误以及其他介质错误，如enc_out, crc err, crc g_eof, c3timeout Tx, pcs 和uncorr 错误。

  • 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Online 且处于In_Sync 状态、并且 Lr_In 大于Ols_out 、这表示问题描述是switchport外部端口。

  • 在Fabriclog 下，可以看到这两个端口在闪烁。

  • 根据sfpshow 输出、交换机端的SFP光学值处于最佳范围-

RX Power:   -1.7   dBm (681.90uW)
TX Power:   -1.5   dBm (701.10 uW)
 

  • 交换机记录了C4-5040 消息-

    2024/09/17-20:13:45:225851 (IST), [C4-5040], 2240091/0, SLOT 1 | CHASSIS | PORT 3/11, INFO,  SWITCH, Link loss of sync debouncing event detected: Slot 3/Port 11(122)

     

  • c4-5040 当由于同步丢失而重置端口链路时、会记录-。将启动反跳计时器以清除同步信号的丢失。如果即使在上述计时器到期后仍未清除、则会发布C4-5040防抖动日志。

  • 在fabriclog 中、我们会看到端口脱机、并且   交换机上出现LR_in

  • 在MAPS policy 中  ，我们可以通过 link fail ,loss sig 和LR 报告：

映射端口3/11的警报：

LOSS_SYNC(SyncLoss) -

LOSS_SIGNAL(LOS)   3/11(1)

  • 在旧的supportsaves中查看sfpshow 端口时、  可以看到RX 电源 出现故障、但仍具有相当高的价值

  •  在errdump 日志下触发的规则defALL_32GSWL_SFPRXP_63 和defALL_OTHER_F_PORTSSTATE_CHG_5 以及loss signal 、link failures 和frame timeout detected 错误。

  • RuleName=defALL_32GSWL_SFPRXP_63Rx电源开始降级时触发、表示上游问题描述I、e  SFP或缆线出现故障

  • 在存储 端、EMS 日志会报告link break 事件：

  • 涵盖问题描述Time  ITW errors 和loss of sync 的性能归档同时进行。

ITW-ERROR.png

 

  • 在交换机端、我们也可以看到loss of sig 错误。

  • 这表示交换机和存储之间的链路上发生了一些loss of signal、因此、存储启动了链路重置以从这种情况中恢复。

  • 这反过来又会触发ITW errors 、因为在此期间重置链路时、到达该链路的帧将被丢弃。

  • ITW 错误指示电缆有故障。
