Just wanted to check whether vpp supports 400gig of throughput ?
Yes, 1+Tbps of IPsec was demonstrated a few years back for example, search for 
Intel whitepapers on VPP.

If yes, which will be the better traffic generator to test 400gig traffic.
Trex should be able to generate that with a big enough machine. Other options 
should work as well.
