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 Contact:7416733224 9475209510
