Usually portmask is parsed with the -p option (depends on the app), followed by an hexadecimal value. So, for instance, -p 0x5 will use ports 0 and 2 from the ports bound to one of the DPDK drivers. Regarding to your second question, number of ports are independent of number of cores. A single core can handle several ports, and even several cores can handle a single port (using different queues). Regards, Pablo > > Regards > Shankari.V
