I have searched all over the internet and did not came across anyone facing such error. kindly guide me about this error. I am attaching the screenshot of the error.Master lcore not available for port error default configuration file part 1 default configuration file part 2

Answer 1

One can not pass the master core as RX or TX core for any port for pktgen. Since this will be running periodic handler for CLI and other services.

Please change the core to port mapping [0:1].0-3 to [1].0. This will make port 0 to use core 1 to run RX and TX.
