He has SR-IOV configured. I managed to repeat with cxl / lagg / bridge / epair (vnet) on 13.2-RC3. Al= so tried re / ue . > tcpdump -i cc0: > 10:00:17.981050 ARP, Request who-has 10.20.20.254 tell 10.20.20.77, lengt= h 42 > tcpdump -i cc1: > 10:00:17.981041 ARP, Request who-has 10.20.20.254 tell 10.20.20.77, lengt= h 28 > 10:00:17.981282 ARP, Reply 10.20.20.254 is-at 02:11:22:33:44:55 (oui Unkn= own), length 46 You might want to tcpdump on cc0 with `--direction=3Din` to filter ARP requ= est send out from cc1 and then come back to cc0 (the switch forwarded it). The IF_BRIDGE(4) seems to hide some thing to protect itself get confused. If you can confirm, then please config you switch properly. The two ports c= c0 and cc1 connected should be in same link aggregation group. I'll see if I can teach IF_BRIDGE(4) to emit warnings in case it get ARP request packet sent from it self. --=20 You are receiving this mail because: You are the assignee for the bug.=
