Change the [2:3].1 to [2:3].0 the reason is you removed one of the two ports and Pktgen starts port counting from zero for the first available port :-) Sorry, I did not spot that sooner. > >The two "-f" pkt files are attached to this email, I do "start 1" >manually at the pktgen prompt. > >Thanks for your time, > >Sincerely, > >Laurent > > >> > >> >Laurent >> > >> > >> >> >> Regards, >> Keith >> >> >> >> > > Regards, Keith
