I am using VMXNET3 type VM .OS distro=UBUNTU14.04.
My VM is having  4 core CPU
                             4 GB RAM

In l2fwd application in dpdk source code after receiving the packet I am
changing the Destination MAC address.

The below is my set UP:

1.Pinging from one VM having IP:;MAC ADDR: 00:0c:29:f2:a7:7e

 2.One VM from where I am running dpdk l2fwd application having three
virtual interfaces: ens160(IP:,
ens192 and ens224 I have binded with dpdk driver (igb_uio)

3.Another one VM to which I want send the packet by changing the MAC
address in dpdk application having IP:;MAC ADDR:

  The packet I can see in the dpdk application as==
  source IP:
  Dest IP:

Now before tx I am changing the dest mac addr for every packet  with
So Ideally It should reach to the dest.

I am running tcpdump on the destination machine but there is no packet
from where I am pinging.

The command I am running to run the app:
./build/app/l2fwd -c 3 -n 2 -- -p3  --no-mac-updating

Please any clue!!!Thanks in advance!!

Thanks & Regards,
Sagar Singha
