Hi I'm trying to do a packet capture on the DPDK interface while running l2fwd sample application and injecting packets from a traffic generator. I'm getting the below error when I give this command: sudo ./build/l2fw-c 0x03 -n 2 -- -p 0x03 --vdev 'eth_pcap0,tx_pcap=/home/controller/pkt_capt/try.pcap'
Pls let me know if I'm missing something. I also tried checking the documentation and confirmed that the ordering of the options is correct. But still I'm getting this error. I also tried various combinations like: But none of them worked. sudo ./build/l2fwd -c 0x03 -n 2 --vdev 'eth_pcap0,tx_pcap=/home/controller/pkt_capt/try.pcap' --p 0x03 sudo ./build/l2fwd -c 0x03 -n 2 --vdev 'eth_pcap0,tx_pcap=/home/controller/pkt_capt/try.pcap' -- -p 0x03 sudo ./build/l2fwd -c 0x03 -n 2 --vdev 'eth_pcap0,tx_pcap=/home/controller/pkt_capt/try.pcap' sudo ./build/l2fwd -c 0x03 -n 2 --p 0x03 --vdev 'eth_pcap0,tx_pcap=/home/controller/pkt_capt/try.pcap' sudo ./build/l2fwd -c 0x03 -n 2 -- -p 0x03 --vdev 'eth_pcap0,tx_pcap=/home/controller/pkt_capt/try.pcap' sudo ./build/l2fwd -c 0x03 -n 2 -- -p 0x03 sudo ./build/l2fwd -c 0x03 -n 2 -- -p 0x03 --vdev 'eth_pcap0,tx_pcap=/home/controller/pkt_capt/try.pcap' EAL: Detected lcore 0 as core 0 on socket 0 EAL: Detected lcore 1 as core 1 on socket 0 EAL: Support maximum 64 logical core(s) by configuration.
