"pfcount -i eth2"? The messages about promiscuous mode suggest pfcount is looking at eth0. You can confirm that by looking at the pfcount output that comes before what you quoted. -don

I have two machines connected back-to-back: (A) has a Silicom NIC ; and (B) has a NetEffect 10GbE NIC. I launch pfcount on A. Then on B I start pinging A. pfcount continually reports zero packets received. ========================= Absolute Stats: [0 pkts rcvd][0 pkts dropped] Total Pkts=0/Dropped=0.0 % 0 pkts - 0 bytes [0.00 pkt/sec - 0.00 Mbit/sec] ========================= Actual Stats: 0 pkts [1'000.06 ms][0.00 pkt/sec] ========================= The only relevant log messages I see are: ixgbe 0000:06:00.0: eth2: NIC Link is Down ixgbe 0000:06:00.0: eth2: NIC Link is Up 10 Gbps, Flow Control: RX/TX device eth0 entered promiscuous mode device eth0 left promiscuous mode [PF_RING] --> handle_hw_filtering_rule(command=0) [PF_RING] --> handle_hw_filtering_rule(command=0) [PF_RING] --> handle_hw_filtering_rule(command=1) [PF_RING] --> handle_hw_filtering_rule(command=1) As I look around I don't see the problem. I can see the packets as they are transmitted on B. And the RX packet count for eth2 that is displayed by ifconfig increments appropriately on A. But pfcount doesn't see them. Anyone have any suggestions? ifconfig -i eth2 ------------------- eth2 Link encap:Ethernet HWaddr 00:E0:ED:FF:18:08 inet addr:10.0.2.45 Bcast:10.0.2.255 Mask:255.255.255.0 inet6 addr: fe80::2e0:edff:feff:1808/64 Scope:Link UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:719669104 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1066541584248 (993.2 GiB) TX bytes:0 (0.0 b) Memory:fd7e0000-fd800000 cat /proc/net/pfring/info -------------------------- PF_RING Version : 5.0.0 ($Revision: exported$) Ring slots : 4096 Slot version : 13 Capture TX : Yes [RX+TX] IP Defragment : No Socket Mode : Standard Transparent mode : Yes (mode 0) Total rings : 1 Total plugins : 0 cat /proc/net/pfring/<pid>-eth2.30 -------------------------------------------- Bound Device : eth2 Slot Version : 13 [5.0.0] Active : 1 Breed : DNA Sampling Rate : 1 Capture Direction : RX+TX Appl.
