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?

please share the version for pktgen, DPDK and OS. If you are using physical interface the driver and firmware version. Also share `pktgen cmdline used` for easier debug. Hence marking the question `needs clarification` – Vipin Varghese Jan 12 '21 at 02:45

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
