Subject: [dpdk-users] After changing Destination MAC address in dpdk packet not reaching to destination
Date: Tue, 5 Sep 2017 11:56:36 +0530 [thread overview]
Message-ID: <CAKXXrHcEV7c8pROuN8aRcKSLuV3omrZwiigHT=sNUDsZzKncAg@mail.gmail.com> (raw)
Hi,
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:10.0.102.72;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:10.0.102.166),
ens192(IP:10.0.102.81),ens224(10.0.102.123)
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:10.0.102.106;MAC ADDR:
00:50:56:a8:6a:d4
The packet I can see in the dpdk application as==
source IP:10.0.102.72
Dest IP:10.0.102.81
Now before tx I am changing the dest mac addr for every packet with
00:50:56:a8:6a:d4.
So Ideally It should reach to the dest.
I am running tcpdump on the destination machine but there is no packet
form 10.0.102.72
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
