问题描述

设备型号和版本：S7506X R7634P10

故障现象/问题描述:

交换机Chassis 1 Slot 0的cpu高，取消本地镜像1后正常,重新配置又会高:

[ZJHZ-PC-WIFI-SW003-7506x-ATZXZTYC_T1_114-probe]dis cpu-usage

Chassis 1 Slot 0 CPU 0 CPU usage:

Chassis 2 Slot 0 CPU 0 CPU usage:

高的进程是：

608 39.5% 36.5% 32.2% [bRX1]

打印发现都是如下业务报文,应该是镜像的报文上cpu了:

目前仅有一个镜像组:

[ZJHZ-PC-WIFI-SW003-7506x-ATZXZTYC_T1_114]dis mirroring-group all

Mirroring group 1:

Type: Local

Status: Active

Mirroring port:

Ten-GigabitEthernet1/0/0/25 Inbound

Ten-GigabitEthernet1/0/0/26 Inbound

Monitor port: Bridge-Aggregation8

过程分析

本地以复现，目前看是芯片上的限制,当目的端口是聚合口,同时聚合口端口down时,报文备误匹配上送cpu.

解决方法

1.删除镜像配置,或者保持聚合目的端口up规避.

2.后续发布版本解决.
