使用watch ifconfig命令观察rx drop的变化情况,发现每2s增加一个drop包。(怀疑存在特殊流量) 使用ethtool -G p105p1 rx4096增加网卡的ring buffer,drop情况无变化。 将这台服务器的p105p2跟另一台服务器的p111p1端口互联,进行数据传输,未发现rx drop数据。 将p111p1网卡接入网络交换机,该网卡开始drop包,每2s一...
unsigned long rx_dropped; /* no space in linux buffers */ 所以既不是硬件问题（否则根本收不到包），也不是arp攻击（驱动不管上层协议类型的），有可能是内存不够，但是不能确定，楼主可以查一下你网卡的驱动程序确认下
I wonder if some of my packets could be leaking into the linux driver? They don't show up in the stats from ifconfig. Cheers, Mark Edit: The DPDK example app l2fwd also exhibits about a 10% packet loss in my test setup. It does not, unfortunately, show the D...

Rx packet drop is seen when we are running a workload which consumes ~45-50% of the port. Only 1 port NIC is connected as of now. No Tx drop is seen. In our workload load is more on Tx compared to Rx. Attaching SAR command output $sar -n DEV 1 1 | grep eno12399 ...
在Linux内核中-网络设备驱动这块,RingBuffer是一种用于管理数据传输的数据结构,特别是处理网络接口的发送(TX)和(RX)接收队列时。 TX Queue: Transmit Queue(发送队列) RX Queue: Receive Queue(接收队列) A:TX(发送)队列干的事: 发送队列用于存储即将由网络接口发送出去的数据包的描述符。当上层软件(如操作系统...
Since the timeout is in jiffies it won't timeout. Even with these additional fixes the driver is still not able to provide a proper FIFO which doesn't drop packages. So change the driver to use rx-offload and base order on timestamp instead of message box numbers. As a side affect,...

The NVM version is v6.8 I used and attachment is the logs. My questions are : What is "port_rx dropped" meaning? What`s the impact when I see the port_rx dropped ? Are there any suggestions for me to debugging? Thanks Chihta port_rx drop.zip 0...
