How to generate RANDOM traffic via Pktgen-DPDK?

Question

I use range <portlist> src|dst ip <SMMI> <ipaddr> as the pktgen doc, and start all to send out packets. But it doesn't work. Do I miss some steps?

Answer 1

DPDK PKTGEN does not dynamically create randaom packets, instead it can be programmed with range option for desired start, minimum, maximum and increment factor. To generate packets with DST-MAC address for a given range using the following commands in pktgen cli

enable all range
page range
range all dst mac start 00:00:00:00:00:01
range all dst mac min   00:00:00:00:00:01
range all dst mac max   ff:ff:ff:ff:ff:ff
range all dst mac inc   00:00:00:00:00:01

As per pkgetn range options one can change MAC, IP, VLAN, MPLS and GRE with range option.

note: tested on pktgen-20.03.0
