BakaKunahi all, is it possible to see which port is the busiest in OVS?11:15
numansBakaKuna, you can see the tx/rx and see if a port is busy ?11:16
BakaKunanumans: I'm thinking about a way to order 690 ports highest tx/rx -> lowest tx/rx :)11:17
numansBakaKuna, may be you can see/inspect/query the ovs interface rows in ovs conf.db11:20
numansovs-vsctl get interface <iface_name> statistics11:20

ragezorHello, does anyone know if I have actions=NORMAL on one of my  flows. Will it forward the packet to the vxlan port also? Or just regular ports?13:42

fbl ragezor: action normal will use mac learning, so if OVS doesn't know where the destination is, then it will flood the packet to all ports in the bridge including the vxlan port. If it does and it is behind the vxlan port, then that is used, otherwise the packet goes only to the port with the destination mac.14:09
BakaKunanumans: thanks! Sorry, I was in the middle of an incident, but I am going to check this out.14:20
ragezor@fbl I have vxlan interface set up and when I ping another host I can see ARP packets on the wires that are connected to the normal ports. but host is behind vxlan tunnel and I don't see ARP packets being transmitted over the tunnel. when I set up the ARP record manually with ip neigh add ping works just fine.14:22
ragezorI've just changed from actions=NORMAL to actions=vxlan0 for the flow and ARP packets are being sent over vxlan port. So my conclusion is that actions=NORMAL does not include vxlan port.14:27
fblragezor: well, both vxlan endpoints need to resolve ARPs or the tunnel will not work.14:28
ragezorvxlan tunnel is working, it's just that if I have actions=NORMAL it seems that flooding does not include vxlan port14:29
fblragezor: if I recall correctly, the packet will dropped at the vxlan port if the destination endpoint is not resolved.14:31
fbl*will be dropped14:32

ragezorI just realized that when I have actions=NORMAL I don't supply VNI and remote IP for the vxlan15:03
ragezorso ofcourse it doesn't work15:03
