接上监控网络, CPU就达到65%以上,路由器有死机现象,请问这种问题,要怎么解决。监控网络中只有17台硬盘录像机,全固定IP

最佳答案
CPU最高在65%左右,过了10分钟就下来了,这样的现象是规律性出现吗?每次都是10分钟左右恢复吗?70%的CPU利用率说实话,不应该打死路由器的,这个现象跟我以前碰到的一个很像,怀疑是有突发流量了,建议做一下如下操作:
1、修改接口统计时间为5秒钟:flow-interval 5
2、找一个没有用的接口,接一台PC,用于出问题是,telnet上去,或者使用console口上去也可以
3、问题出现了,登录设备,用display interface gx/x看接口详细信息,主要看last 5 second input/output的流量,看看那个接口流量很大,也要看接口下的fifo队列里有没有报文
如果是流量比较大,并且伴有fifo队列丢包,那就说明有服务器在一瞬间发了很大的报文出来,把路由器打死了,需要查一下是那台服务器,是不是中毒了

这个是监控的硬盘录像机,没有服务器
就用这个flow-interval 5命令就可以了吗?
对,命令就是那个,把接口下统计流量的间隔改成5秒,默认是5分钟的
非常感谢,我先去查下,查到了再咨询您!

<H3C>display process cpu 可以看一下具体哪个进程高,当然这些信息只能交给华三售后去定位了。
[kdrvdp3]这种代表转发核,转发核高的话就要看现场业务量是不是很大?或者路由器收到攻击?
