I see:
> bond balance-slb: member ens4f1v25: admissibility verdict is to drop pkt as different port is learned, active member: true, may_enable: true, enabled: true, LACP status: off
This indicates that OVS thinks it's getting a packet on the wrong port. This could be due to the switch, or the nic driver, or OVS.
You run "tcpdump -i bondbridge" but in this case I'd recommend "tcpdump -i ens4f1v25". Or whatever one leg of the bond member is. This would indicate if we actually do see the packets coming in on the correct leg.
I'll try and set up a reproducer, Intel nic right?
Hello Mike
> I'll try and set up a reproducer, Intel nic right?
yep, I use xxv710 NIC.
I try run same test on 5.14.0-318.el9.x86_64 + openvswitch3.1-3.1.0-24.el9fdp.x86_64 and still can see below message on ovs-vswitchd.log
