Brocade Switches – 如何确定是SFP 或是光纤线导致“Loss of Link（丢失链接）”问题
问题描述:
一个有问题的SFP或光纤线会造成丢失与主机，存储或另一台交换机的连接问题，在交换机的error log中可能有如下显示:
2007/12/06-23:50:56, [FW-1424], 7682,, WARNING, SWITCH_1, Switch status changed from HEALTHY to MARGINAL
2007/12/06-23:50:56, [FW-1436], 7683,, WARNING, SWITCH_1, Switch status change c
ontributing factor Marginal ports: 1 marginal ports. (Port(s) x )
问题解决方法:
首先确定是由于SFP还是光纤线的问题造成链接丢失，执行下面的命令：
检查porterrshow命令的输出：
如果仅是"enc out "单独报错主要是因为光纤线的问题。
如果是"enc out夜总 "和"crc err "组合报错主要是GBIC/SFP的问题。
要确定是源端还是目标端SFP报错，需要再检查"portshow x" 的输出（x代表有问题端口号）
