Hi, We have 2 Worker threads. Each thread is pinned to one Core, so total 2 Cores. All are in One NUMA node, with Socket 0.We have also below config.
1. socket-mem 2048 num-rx-queues 1 num-tx-queues 3 num-mbufs 61000 2. With IPSEC,GCM128 algoritm Reassembly Buffer 8192 . Traffic profile which we are testing : IPSEC Algorithm Used :GCM128 Traffic received at one interface (Downlink) is Encrypted traffic and 50% of the received traffic is fragmented traffic destined to the DUT-VPP. Traffic pumped from the other connected entity at 5.5Gpbs in Downlink direction. We observe the below error in "show hardware interfaces " : *rx-mbuf-allocation-errors* and *rx missed errors* * * EthernetSwitch2/0/0 2 up EthernetSwitch2/0/0 Intel FM10000 Family Ethernet Switch carrier up full duplex speed 50000 mtu 9990 flags: admin-up pmd maybe-multiseg subif rx queues 1, rx desc 8192, tx queues 3, tx desc 8192 cpu socket 0 tx frames ok 22341752 tx bytes ok 7128341512 rx frames ok 44697952 rx bytes ok 32081699092 rx missed 7083446 extended stats: rx good packets 44697952 tx good packets 22341752 rx good bytes 32081699092 tx good bytes 7128341512 *rx missed errors 7083781* rx q0packets 44697952 rx q0bytes 32081699092 rx q0errors 7083781 tx q2packets 22341752 tx q2bytes 7128341512 *rx mbuf allocation errors 7083446* rx q0 packets 44697952 rx q0 bytes 32081699092 rx q0 dropped 7083446 tx q2 packets 22341752 tx q2 bytes 7128341512 Request experts to show some light on the reason behind these errors? Also request experts to suggest any hack/workaround to get over this? [ NB: From FDIO doc," The number of buffers are calculated from the number of rx queues. The number of RX,TX Descriptors and TX queues are calculated from the number of RX queues. ]
