I'm having problems getting pfcount to work. 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
