I believe you’ll see this error if pktgen was not compiled with lua support. Check that pktgen is compiled with lua enabled, in the meson_options.txt file.

https://github.com/pktgen/Pktgen-DPDK/blob/dev/meson_options.txt#L1

In my build notes I have the following, but I’m unsure if this still applies. I have not tried a recent version.

make buildlua
meson build

Subject: Pktgen failing to execute with Lua scripts

Hi Community,

I’m trying to execute pktgen using lua scripts.

The command I’m using is :
 ./usr/local/bin/pktgen -c ffffffff -n 4 —proc-type auto —file-prefix pktgen1 —P -m “29.0” -f test/dump.lua

But after instantiating, I see it displaying this message:
>>> User State for CLI not set for Lua

Is there anything we should be setting before trying to execute Lua scripts? Would highly appreciate some inputs on this.

Thanks
Saniyya
