I did try giving the pcap file in the -s option but I was not able to see a= ny pcap files getting generated by the pktgen. I also tried giving in the -f option but it also doesnt seem to recognize. Please let me know how to resolve this.

I have a PCAP file which contains LLDP frames in it. I heard that pktgen has the ability to generate the packets specified in in= put pcap file. I checked the options available with pktgen and can see only -s and -f opti= ons to be relevant. But -s option seems to indicate the output pcap file, and -f option is for = specifying the Lua script or command list to execute. KW: The -s P:PCAP_file is used to define the port and file for sending via = Pktgen, so the =96s option is the correct one to use. Hence please let me know which option I need to use for specifying the inpu= t pcap file from which the pktgen should generate the packets from, Also would like to know how I can specify the transmit and receive ports s= eparately in the pktgen commandline Regards Shankari.V
