[ovs-discuss] Test with vxlan using ovs-dpdk (2.4)

[Praveen MANKARA RADHAKRISHNAN]

Hi Sugesh,

Thanks for the reply.
arp entries are show in vs-appctl tnl/arp/show command. but it seems o
packet is coming to the bridge with physical port.

I have already tried to set using tnl/arp/set command but it seems set is
not present in openvswitch 2.4
it returns the following error.

"
ovs-appctl tnl/arp/set br0 10.200.0.6 02:11:22:44:55:11
"tnl/arp/set" is not a valid command
ovs-appctl: ovs-vswitchd: server returned an error "

One important thing is to note that i was using dpdk-2.0.0. does that make
any difference?

Thanks
Praveen
