X-BeenThere: users@dpdk.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: DPDK usage discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: users-bounces@dpdk.org Sender: "users" Hi everyone, We are seeing a strange issue with X710 NICS and DPDK enabled VMs. - After a shutdown of the port facing the compute (and the DPDK VM), we seem to have random vlans that are not seeing traffic through the VF. - We we're able to run a packet capture in the VM and it's not seeing any traffic. - We are not seeing any incoming packets on the TOR either. - We we're able to temporarily fix the issue by running a "tcpdump" on the SRIOV interface on the compute - this fixed most of the cases we've seen but I have one instance where the same action doesn't allow the traffic to recover. - We have 9 VLANS on the VM and it always seem to impact just one of the vlan interface. I have never seen more than 1 fail to receive traffic. Hardware/Drivers Overview: - X710 NIC cards - DL360 G10 - Red Hat 7.6 running on the hypervisor. - StarOS (Cisco proprietary-ish OS) - looks like a RHEL derivative. - Firmware on the 10GB cards : 10.3.5 - RedHat i40e driver : 2.3.2-k As anyone seen anything similar with DPDK aware VMs? Let me know if you need any more details. Thanks!
