Hi All, I just tried with: OpenBSD host 5.9 GENERIC.MP#1888 amd64 The result is still the same. Networking stops and sometimes continues after some time. Could this because of SMP networking?
What I am seeing on the switch is that the MAC address is still in the MAC table. But there is no longer an ARP entry.
