https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D221754 Bug ID: 221754 Summary: arp: packet with invalid ethernet address length 0 received Product: Base System Version: 11.1-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: pzhel@iihr.ru We have two Virtual FreeBSD machines on Hyper-V 2008R2 server.=20 VM#1 - FreeBSD 10.3-RELEASE-p18 amd64 VM#2 - FreeBSD 11.1-RELEASE amd64 Both VM's connected to the same LAN 192.168.0.0/17 On VM#2 /var/log/messages permanently registering an error arp: packet with invalid ethernet address length 0 received on hn0 tcpdump on hn0 show this 17:48:17.035879 ARP, Ethernet (len 0), Unknown Protocol (0xf000) (len 1), length 50 Quick Google search show that such packets can be generated by D-Link DES/D= GS Metro series switches. We have a number of D-Link switches in our LAN, but = we never see this error on FreeBSD 8.x/9.x/10.x before Can it be fixed? Or,how we can supress this error messages on 11.1, because replacing D-Link switches is not a solution. --=20 You are receiving this mail because: You are the assignee for the bug.=
