Hi Shyam,

In your case try the following:
./l2fwd -c f -n 2 -- -p 0x3 where -p 0x3  indicates that you want to use port 0  and  port 1 with the l2fwd app.

For future experiments you'll need read through the dpdk documentation so you can gain better understanding.

Regards,

Hristo

Thanks, Yes indeed we need to go through documentation, my case I was in
hurry passing through commands to get into real action so missed the dpdk
specific "--" separating EAL and app specific options. I realized my
mistake soon afterwards while looking at app code, updated the thread on
web list archive, probably another mistake !
I am moving well with my project using dpdk  for now ...
Regards

[dpdk-users] Port binding issues : NIC intel 82599ES

[Shyam Shrivastav]

Hi
I just started on dpdk, was trying to run l2fw. I bind two 82599 ports
using dpdk-devbind to igb_uio (first tried uio_pci_generic with same
result), then run l2fw but EAL is unable to probe these drivers still
getting ixgbe. Here is the console output

[root@unassigned build]# dpdk-devbind --status
