问题描述

设备型号S5700-52C-EI

版本:V200R001C00SPC300

问题描述:某局点客户反映,S5700-52C-EI交换机接口上收到了源地址和目的地址都不是接口所连接的服务器的IP地址Tcp单播报文。

告警信息

处理过程

步骤一:通过抓包查看链接服务器端口报文

步骤二:察看0号和 1 号芯片上的mac地址并反馈,然后对比下看是否mac在两个芯片上是否致

根因

mac地址在交换机的两个芯片之间没有同步,导致单播报文查不到目的mac地址而广播引起的

解决方案

通过升级版本解决,可以升级到V200R005C00SPC500 ,并打上最新补丁V200R005SPH012
