Hi,
I'm now simply trying to use two ports in a single pktgen-dpdk instance
(maybe I do not need the two instances...), but still I have a problem
Pktgen Ver: 3.5.1 (DPDK 18.08.0-rc0)
Powered by DPDK ** Version: DPDK 18.08.0-rc0
trying to use two ports as follows, it stops with an error (see below)
sudo -E ./app/x86_64-native-linuxapp-gcc/pktgen -l 0-4 -n 3 -- -P -m
"1.0, 2.1"
while using a single port at a time is OK:
sudo -E ./app/x86_64-native-linuxapp-gcc/pktgen -l 0-4 -n 3 -- -P -m "1.0"
sudo -E ./app/x86_64-native-linuxapp-gcc/pktgen -l 0-4 -n 3 -- -P -m "2.1"
any suggestion will be appreciated!
ciao Stefano

OK now I see the pktgen and dpdk versions.

Another place to look is in the pktgen/cfg directory at files master.cfg and slave.cfg (bad names as they are not master and slave processes) In these files are python data statements and are used by pktgen/tools/dpdk-run.py command as so.
$ ./tools/dpdk-run.py master
$ ./tools/dpdk-run.py slave
You can copy these files and edit them for your use call them say pktgen-1.cfg and pktgen-2.cfg then run
$ ./tools/dpdk-run.py pktgen-1
$ ./tools/dpdk-run.py pktgen-2
I hope that helps.

Hi Keith,
thanks for your support, we have understood the root of the problem
we simply had to increase the vm.nr_hugepages in /etc/sysctl.conf from
256 to 2048
this way, we were able to use two ports in the same pktgen instance as
well as to run two separate primary instances of pktgen
ciao
Stefano
