I'm not sure because of it, i want to use tool PKTGEN.
When i use this tool and start packet sending, its link is down and i can't send packet.
I want to use this tool and make simulation.
and also l2fwd doesn't work.

Hi,

I think your platform doesn’t have more than 1 NUMA node (node 0. See message " NUMA node(s):          1"). And you are giving ‘-n 4’ in command line.
That might be the reason this warning is being reported before defaulting back to node 0.

Does this create any function issue? Like not having I/O in l2fwd/l3fwd application?

I don't have a solution - but, I can suggest that if you can paste output of your execution here, someone might give you hints.
Don't forget information about environment (platform, 'cat /proc/meminfo', etc). More the info about what you have attempted or trying to attempt, easier it is to point out possible problem area.
