[ovs-discuss] invalid Ethertype 0 in flow key

[Jamshaid Faisal]

hmm i got some more info actually
if i use options:dst_port=xxxxx  in vxlan setup command above, i dont get
those errors in log. It means i have to use dst_port
however i read this in documents

"By default, Open vSwitch will use the assigned IANA port for VXLAN, which
is 4789"

Whats really going on there, VXLAN works without specifying dst_port but
with these errors in log.
so should i use dst_port ?
