核心直连服务器,ping的时候,有较大的时延,有些响应是1点多ms,有些达到53ms,一请问一般是什么导致

最佳答案
把连接服务器的线缆接入到PC看看,是否还存在这么大的延迟,要不就是服务器做了ping的处理限制,要么就是交换机对ping报文的转发速率有底层限制,因为icmp的报文交换机处理优先级默认是最低的,或是你可以看下是不是出接口跑满了

看下物理接口有没有错误包 端口速率是否正常
(0)
没有错包,速率也正常
没有错包,速率也正常
交换机ping服务器还是服务器ping交换机,可以看下服务器的负载情况,另外也可以用终端ping试试

设备有ping保护机制,对自身发出的或以自身为目的地址的icmp报文有硬件和软件上的限速。
所以有抖动是正常的,不丢包就行。虽然也可以解除这个机制,但是不推荐。
查看硬件、软件限速:
