I am not going to be much help as I do not and have not used BIGIP. I assume you have the Pktgen that supports bonding mode 4. The previous Pktgen version would not call tx_burst() unless it had something to send, which the bonding driver requires tx_burst() with zero packets at least at a given interval. The latest versions do call tx_burst() with zero pkts at least within the needed timing. > > > packet tx/rx works : > > 1 Pktgen with DPDK net bonding mode 1, 2, 3, 5 > 2 BIGIP trunk with LACP disabled (trunk port status UP) > > packet tx/rx failed: > > 1, Pktgen with DPDK net bonding mode 4 802.3AD > 2, BIGIP trunk with LACP enabled (trunk status is DOWN) > > or > 1, Pktgen with DPDK net bonding mode 4 802.3AD > 2, BIGIP trunk with LACP disabled (trunk status is UP) > > my end goal is to achieve 10G < througput < 20G with Pktgen DPDK net > bonding with Intel 82599 to load test BIGIP, so far with bonding mode 1, > 2,3, 5, I am unable to achieve throughput > 10G.
