Hi Damjan, > You likely need to utilise RSS on rx side to equally load your cores, Could you please let me know how I configure RSS?  I do not know how I configure RSS because this device is given to vpp/dpdk. It is bound to igb driver. Is it specified in startup.conf or CLI command? Thanks Cha

Hi Yichen, Thanks for the response. I have issue on the transmit path. I think the cores are assigned properly in the configuration. Thanks Chakri -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group. View/Reply Online (#10016): https://lists.fd.io/g/vpp-dev/message/10016

Hi Damjan, Thanks for your feedback. I'm running the test in AWS instances. Thus, I have got only VFs. I do not have access to PF. So, I'm trying to get help from AWS to find out. Once I get the info, I'll post it over here. In the mean time, I looked at the counters that you suggested me to fo

Re: [vpp-dev] tx-errors on VPP controlled dpdk device

Try to dump hardware counters with "show hardware" That my give you more information what's wrong... As you are using VF, my wild guess is that you may have promisc mode disabled. Try to dump PF details with 'ip link show dev XXX" -- Damjan > On 1 Aug 2018, at 00:52, chakravarthy.arise...@via
