TS系列之–2960X交换机Uplink口无法识别SFP光纤模块

近期项目采购了15台2960X交换机,上线13台,大约运行1周左右,11台交换机UPlink口出现故障,无法识别到SFP光纤模块。

并且设备会报如下错误信息:

hulc_sfp_iic_intf_read_eeprom sfp _index 2 yeti_iic_read_retry fail

hulc_sfp_iic_intf_read_eeprom sfp _index 2 yeti_iic_read_retry fai

通过show interface 命令,该端口处于notconnect的状态,指示灯不亮

sale_11F_C2960X_01#show int g1/0/51

GigabitEthernet1/0/51 is down, line protocol is down (notconnect)

但是查看对端3750-12S交换机端口状态都是up,正常的。

将交换机重启后,故障现象依旧,但是又出现如下报错信息:

%ILET-1-AUTHENTICATION_FAIL: This Switch may not have been manufactured by Cisco or with Cisco's authorization.  This product may contain software that was copied in violation of Cisco's license terms.  If your use of this product is the cause of a support issue, Cisco may deny operation of the product, support under your warranty or under a Cisco technical support program such as Smartnet.  Please contact Cisco's Technical Assistance Center for more information.

看到这个信息,差点把客户逼疯了,根据经验如此大面积出现故障,可能是BUG的可能性比较大,而且也查了一下资料,也提到 有软件BUG的可能性,只能先升级软件试试了,看到2960X思科对‘c2960x-universalk9-mz.150-2a.EX5.bin’这个 版本做了特别的推荐,于是下载,copy到FLASH, 然后boot system flash,最后reload。发现故障并没有解决。

最后实在没办法了,只能求助思科了,把情况和TAC沟通了,TAC说升级软件之后,不要reload,要断电重启,此BUG就会消除了。晕,这个BUG实在是太诡异了。

总结一下2960X交换机UPlink口 无法识别SFP光纤模块解决方法:

1.升级软件到c2960x-universalk9-mz.150-2a.EX5.bin

2.断电重启(此步骤非常关键)
