某局点S10508X 出端口流量速率100%,配置本地镜像后速率回落正常问题

/

/

设备型号：S10508X Version 7.1.070, Release 7624P12

现场监控平台反馈当前设备的g1/3/0/3接口，出方向流量速率100%,存在异常；按理只有如下四个接口上来的流量，会通过G1/3/0/3发往华为云:XGE2/2/0/5    XGE1/2/0/6  聚合  Bridge-Aggregation40：   XGE1/2/0/9   XGE2/2/0/9 ,不会达到这么高的流量.

于是前方配置本地镜像,想看看是否流量异常转发到路由口了导致,但是配置镜像后g1/3/0/3出方向速率立刻回落正常,取消镜像马上又达到100%.

核查发现是另外一个镜像组3配置不规范,Prob vlan配置了对应虚接口:

删除interface Vlan-interface4000解决.

配置错误,导致报文异常上送cpu复制转发,带宽高,删除interface Vlan-interface4000解决.
