Hi users, Environment =========== DPKD Version : 21.11.9 Bond member slave 1 : Intel e1000e I217 1Gbps "Ethernet Connection I217-LM 153a" slave 2 : Intel e1000e 82574 1Gbps "82574L Gigabit Network Connection 10d3" OS :Rocky Linux 8.10 rhel centos fedora Compiler: gcc (GCC) 8.5.0 20210514 (Red Hat 8.5.0-24)
Steps to reproduce ================== 1. bind ports to dpdk dpdk-devbind.py -b vfio-pci 0000:b1:00.0 0000:b1:00.1 2. launch testpmd ./dpdk-testpmd -l 0-3 -n 4 -- -i --portmask=0x1 --nb-cores=2 --no-lsc-interrupt --port-topology=chained 3. create bonding device port stop all create bonded device 0 0 add bonding slave 0 2 add bonding slave 1 2 port start all show port info all Results: ======== the link status of 1 ports is down ( not specific to mode ) In every bond mode link speed of the slave interface 1 Intel e1000e I217 1Gbps "Ethernet Connection I217-LM 153a" is down. Port 0 Link down Port 1 Link up at 1 Gbps FDX Autoneg Port 1: link state change event Port 2 Link up at 1 Gbps FDX Autoneg Done Expected Result: ================ The status of all ports should be normal. Link status of both member/slave should be up and status of port 0 should not be always down. In mode 0 with bond mode 0 link speed should be 2 Gbps with 2 members each 1 1Gbps. *My Questions:* 1. What could be causing one of the slaves to become inactive ? 2. Is there a specific configuration or step I might be missing that's preventing the bond from utilizing both slaves ? 3. Are there any known compatibility issues or limitations with Intel e1000e I217 1Gbps "Ethernet Connection I217-LM 153a" that could explain this behavior?
