Hi, all
I have a box equipped with 32 cores (2 cpus and hyperthread is enabled) and a
4-port intel 82576 card. There are 2 nprobe running on this machine listening 2
ports which having about 200Mbps(less then 100kpps) on each of them. The
pf-ring version is 5.6 in mode 2.
what I observed about the packet dropping is:
1. the tot pkt lost in /proc/net/pfring/info is 0
2. the tot packet drop in ifconfig for the port is not zero and keep increasing
on the rate of several thousands packet a second.
3. the num free slot remains above 0. so that means the nprobe is fast enough.
so, in this situation, what is the root cause of the packet drop, thank you for
any comment!
Alan
