[dpdk-users] Pktgen: Send bidirectional traffic with Virtual Ports

[Mohan Prasad]

Hi,

I am trying the below setup with 2 virtual ports on Centos 6 and both the
virtual ports are connected to one Virtual Switch.

VP1 <---CENTOS(Virtual Machine)------> VP2

Using pktgen, I am trying to send data from one port to another using start
all command. But i can see data in only one direction and not in other
direction.

Is there any issue with pktgen or with virtual ports? Please do let me know
what should be done to get it working.

Thanks,
Mohan

One option is to start Pktgen with –P option to enable promiscuous mode and see if the traffic is seen in both directions. If you see the traffic in both directions then I would suggest something else is wrong with the other parts of the system. The MAC addresses look fine, but using –P should help detect that problem.
