[dpdk-users] dpdk-pdump does not work

[ikuzar RABE]

Hi all,

I use dpdk on Linux Debian 8 to read packets from XL710 intel NIC and would
like to put them into a pcap file (capture.pcap) using dpdk-pdump
I replay packets from another machine. At the end of replay, I check the
size of captures.pcap. Its size is 0.

I tell dpdk-pdump to read from port 1. But it seems to read from port 2...

Does anyone know what goes wrong ?

here is how I proceeded, as indicated here
http://doc.dpdk.org/guides-18.11/howto/packet_capture_framework.html?highlight=pcap
:

   1. I run testpmd: I see packets stats on port 1
   2. I run dpdk-pdump: it does not dump packets
