Hi Neale,
Thanks for the reply, I notice a problem today for ipv4, I set an IP on multiple interfaces, but during the test, the IP of one of them disappeared. GigabitEthernet3f/0/0 (up): L3 200.85.1.1/24 GigabitEthernet3f/0/1 (up): GigabitEthernet3f/0/2 (up): L3 201.85.1.1/24 I get some errors like this in "sh errors" 469 GigabitEthernet18/0/1-tx Tx packet drops (dpdk tx failure) and like this in syslog: vnet[18135]: dpdk_pool_create:504: ioctl(VFIO_IOMMU_MAP_DMA) pool 'dpdk_mbuf_pool_socket0': Bad address (errno 14) Sep 25 07:35:35 Rahyab22K-1 vnet[23814]: dpdk: unsupported rx offloads requested on port 40: scatter Sep 25 07:35:35 Rahyab22K-1 vnet[23814]: dpdk: unsupported rx offloads requested on port 41: scatter Sep 25 07:35:35 Rahyab22K-1 vnet[23814]: dpdk: unsupported rx offloads requested on port 42: scatter Sep 25 07:35:35 Rahyab22K-1 vnet[23814]: dpdk: unsupported rx offloads requested on port 43: scatter Sep 25 07:35:36 Rahyab22K-1 vnet[23814]: dpdk: unsupported rx offloads requested on port 52: scatter Sep 25 07:35:36 Rahyab22K-1 vnet[23814]: dpdk: unsupported rx offloads requested on port 53: scatter Sep 25 07:35:36 Rahyab22K-1 vnet[23814]: dpdk: unsupported rx offloads requested on port 54: scatter Sep 25 07:35:36 Rahyab22K-1 vnet[23814]: dpdk: unsupported rx offloads requested on port 55: scatter Sep 25 08:31:54 Rahyab22K-1 kernel: [261685.085366] DMAR: DRHD: handling fault status reg 302 Sep 25 08:31:54 Rahyab22K-1 kernel: [261685.091285] DMAR: [DMA Write] Request device [18:00.1] fault addr a9fb91000 [fault reason 05] PTE Write access is not set is this normal?
