If you look at the two scripts in Pktgen pktgen-master.sh and pktgen-slave.sh these two scripts setup two instances of pktgen on the same machine. Plus you can read the README.md file. http://dpdk.org/browse/apps/pktgen-dpdk/refs/ You have to make sure you have enough memory (huge pages) allocated for both instances to run. Then use ?file-prefix XX to give each instance a different prefix for the huge page files in /dev/hugepages if that is the location of the files on your system. I would remove any files in that directory to free up the memory. Use the ?socket-mem to allocate the correct amount of memory for each instances this way DPDK does not consume all the pages for a given instance. Make sure you blacklist the ports you do not want on the first instance using -b option and then blacklist the ports from the first instance while allowing the other ports to be used on the second one. That should do it for most cases. > > Thanks, Keren Regards, Keith
