[ovs-discuss] fail-mode secure behavior

Hello I had a quick question about the fail secure behavior.

I have created a dp0 and added eth3.1750 to it. Then I put  10.43.100.14
 on dp0.

Now if I run ping -I dp0 10.43.100.34 , and run tcpdump on eth3 I see my
arp packets leaving the box even though I have dp0 set as fail-secure.

Is this the expected behavior?

Thanks,

Aaron


Here is my setup:

root at geni1:/users/arosen# ovs-vsctl set-fail-mode dp0 secure

 root at geni1:/users/arosen# ovs-dpctl show
system at dp0:

port 1: eth3.1750
