As mentioned in the comments, the vlan enable is not triggered in the LUA scripts which causes VLAN not to be enabled. I have modified the above lua script to enable vlan,

please find the details below

package.path = package.path ..";?.lua;test/?.lua;app/?.lua;"
require "Pktgen"

-- enable vlan feature, default setting is disabled.
pktgen.vlan("all", "enable");

pktgen.range.dst_mac("0", "start", "00:00:5e:00:01:00");
pktgen.range.src_mac("0", "start", "00:16:00:01:00:01");
pktgen.range.src_mac("0", "inc", "00:00:00:00:00:01");
pktgen.range.src_mac("0", "min", "00:16:00:01:00:01");
pktgen.range.src_mac("0", "max", "00:16:00:01:00:cd");
pktgen.range.src_ip("0", "start", "1.1.1.1");
pktgen.range.src_ip("0", "inc", "0.0.0.0");
pktgen.range.src_ip("0", "mint", "1.1.1.1");
pktgen.range.src_ip("0", "max", "1.1.1.1");
pktgen.range.dst_ip("0", "start", "1.1.1.2");
pktgen.range.dst_ip("0", "inc", "0.0.0.0");
pktgen.range.dst_ip("0", "mint", "1.1.1.2");
pktgen.range.dst_ip("0", "max", "1.1.1.2");
pktgen.set_type("0", "ipv4");
pktgen.set_proto("0", "udp");
pktgen.set("0", "size", 1024);
pktgen.set("0", "rate", 0.25);
pktgen.set("0", "burst", 1);
pktgen.set_range("all", "on");
pktgen.vlanid("0", 9);
pktgen.start(port);

Note:

  1. there are 2 options in pktgen to run the lua from command line use option -f, and within interactive mode use script option.
  2. results for without running the script (left side) and result for after running the script (right side) shared in the image below
