Hi,
Recently in one of the customer field we observed packet drop with Intel XL710 40GbE NIC. Is there any know packet drop/issues with following XL710 Rev02/B1 NIC?
We saw packet drop even though we haven't utilized link capacity 100%. Hardly 50% of link capacity utilized when we observe the packet drop issue.
05:00.0 Ethernet controller: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+ (rev 02)
05:00.1 Ethernet controller: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+ (rev 02)
We have APP which is developed by using DPDK 2.1 version and used XL710 NIC for packet reception/transmission.
Here is the high-level view how our APP RX and TX path connected Router which is immediate node for our APP.
APP <== RX Path======
Router
APP ====TX Path======>
Unfortunately there is no way to measure the actual error packet statistics at APP side as DPDK 2.1 doesn't support the NIC statistics for driver i40e.
Please help us if there is any know packet drop issues with even XL710 B1 seriers. Or some other fine tune tuning required in NIC level.
Thanks in advance for your help.
Regards,
Suresh.
