Hi Alfredo Thank you for your prompt response. We will look into examples you have mentioned. We were using instructions from: http://www.ntop.org/products/pf_ring/hardware-packet-filtering/ Are there any updated instructions we could use?

We are now working on a project that requires hardware filtering on 82599 Intel network card using PF_RING. We have recently purchased PF_RING ZC license for 10 Gbit adapters Steps we have done: - Downloaded downloaded PF_RING-6.0.2.tar.gz - Compiled PF_RING and drivers from PF_RING-6.0.2 - purchased PF_RING ZC license for 10 Gbit adapters (order 1416498630) - downloaded http://www.nmon.net/packages/debian/7.6/all/PF_RING-dkms/pfring-dkms_6.0.3_all.deb and installed it - activated licence per instructions - insmoding pf_ring and ixgbe.ko driver using script in attachment (script is located in /opt/PF_RING-6.0.2/drivers/PF_RING_aware/intel/ixgbe/ixgbe-3.21.2-zc/src) Problems we have: - we don't seem to get file in cat /proc/net/pf_ring/dev/eth2/rules where rules for hardware filtering can be set. /proc is deprecated, you should add/remove rules using the API. Please take a look at the examples in PF_RING/userland/{examples,examples_zc}, for instance ./zcount -h | grep "\-R" - Insmod ixgbe.ko with parameter FdirMode=2,2,2,2 returns: Error: could not insert module ixgbe.ko: Unknown symbol in module FdirMode is deprecated, actually it is not present in the enclosed script. - In dmesg after using load_driver_“.sh script we do not get line: ixgbe: 0000:02:00.0: ixgbe_check_options: Flow Director perfect filtering enabled You should not expect this message in latest driver. I have attached output from dmesg after using script load_driver_2.sh Can you help us determine what are we doing wrong? Thank you in advance, Katarina Valent Best Regards Alfredo
