交换机CPU使用率过高的原因分析及探讨

Reason Analysis and Discussion on the Excessive Switch CPU Utilization

新钢自动化部将物料环网的百兆老网首次接进千兆新网后,二层交换机CPU的使用率达到了80%以上,对导致此现象产生的原因进行分析并采取试验方法进行诊断。远程对所有二层交换机的固件升级后,其CPU使用率降至50%左右。

After the old 100 M ethernet are connected into kilomega ethernet of material ring network of Automation Dapart for the first time in Xinyu Steel,layer 2 switches CPU utilization rate reached more than 80%. The causes of this phenomenon are analyzed and test method are carried out for the diagnosis. After the firmware upgrade of all two layer switches,the CPU utilization rate is reduced to about 50%.
