Thanks Luca.
I am now running a single threaded nProbe instance tied to eth0@X and its
generating flow packets using the command:
nprobe -i eth0@1 -n <IP> -u 1 -Q 2 -V 5
I have some follow up questions.
- How do I know how many instances to start? See load_dna_driver.sh result
below.
- insmod ./ixgbe.ko MQ=1,1 RSS=8,8 FdirMode=0,0
- How can I tell packets received on each queue?
- ‘ethtool –S eth0.rx_queue_X_packets’ shows 0 for all values.
- ‘pfcount –i eth0@X’ and ‘pfcount_multichannel –i eth0’ shows 0 for all
values.

You need to run one nProbe per queue (I.e. -i eth0@X) in single threaded mode
(i.e. remove -O).

Hello,
I installed fresh copies of
- PF_RING 5.0
- nprobe_6.6.3_091011_proplugins
- Using DNA driver
o PF_RING/drivers/DNA/ixgbe-3.3.9-DNA/
- Ubuntu 11.04
After installation, and registering the DNA driver, I use the following command
to launch nprobe:
nprobe -i eth0 -q 10.204.253.104:1111 -n 10.204.253.101:2055 -t 30 -l 10 -s 10
-O 2 -u 1 -Q 2 -V 5
I see every second line below indicates 0 pps and 0 bps. How can I get more
queues to process packets?
Thx, -henning
