+DPDK pdump Library and pdump Tool
+=================================
+
+This document describes how the Data Plane Development Kit (DPDK) Packet
+Capture Framework is used for capturing packets on DPDK ports. It is intended
+for users of DPDK who want to know more about the Packet Capture feature and
+for those who want to monitor traffic on DPDK-controlled devices.
+
+The DPDK packet capture framework was introduced in DPDK v16.07. The DPDK
+packet capture framework consists of the DPDK pdump library and DPDK pdump
+tool.
+
+
+Introduction
+------------
+
+The :ref:`librte_pdump <pdump_library>` library provides the APIs required to
+allow users to initialize the packet capture framework and to enable or
+disable packet capture. The library works on a client/server model and its
+usage is recommended for debugging purposes.
+
+The :ref:`dpdk-pdump <pdump_tool>` tool is developed based on the
+``librte_pdump`` library. It runs as a DPDK secondary process and is capable
+of enabling or disabling packet capture on DPDK ports. The ``dpdk-pdump`` tool
+provides command-line options with which users can request enabling or
+disabling of the packet capture on DPDK ports.
+
+The application which initializes the packet capture framework will act as a
+server and the application that enables or disables the packet capture will
+act as a client. The server sends the Rx and Tx packets from the DPDK ports
+to the client.
+
+In DPDK the ``testpmd`` application can be used to initialize the packet
+capture framework and act as a server, and the ``dpdk-pdump`` tool acts as a
+client. To view Rx or Tx packets of ``testpmd``, the application should be
+launched first, and then the ``dpdk-pdump`` tool. Packets from ``testpmd``
+will be sent to the tool, which then sends them on to the Pcap PMD device and
+that device writes them to the Pcap file or to an external interface depending
+on the command-line option used.
+
+Some things to note:
+
+* The ``dpdk-pdump`` tool can only be used in conjunction with a primary
+ application which has the packet capture framework initialized already. In
+ dpdk, only ``testpmd`` is modified to initialize packet capture framework,
+ other applications remain untouched. So, if the ``dpdk-pdump`` tool has to
+ be used with any application other than the testpmd, the user needs to
+ explicitly modify that application to call the packet capture framework
+ initialization code. Refer to the ``app/test-pmd/testpmd.c`` code and look
+ for ``pdump`` keyword to see how this is done.
+
+* The ``dpdk-pdump`` tool depends on the libpcap based PMD which is disabled
+ by default in the build configuration files, owing to an external dependency
+ on the libpcap development files. Once the libpcap development files are
+ installed, the libpcap based PMD can be enabled by setting
+ ``CONFIG_RTE_LIBRTE_PMD_PCAP=y`` and recompiling the DPDK.
+
+
+Test Environment
+----------------
+
+The overview of using the Packet Capture Framework and the ``dpdk-pdump`` tool
+for packet capturing on the DPDK port in
+:numref:`figure_packet_capture_framework`.

+ Packet capturing on a DPDK port using the dpdk-pdump tool.
+
+
+Configuration
+-------------
+
+Modify the DPDK primary application to initialize the packet capture framework
+as mentioned in the above notes and enable the following config options and
+build DPDK::
+
+ CONFIG_RTE_LIBRTE_PMD_PCAP=y
+ CONFIG_RTE_LIBRTE_PDUMP=y
+
+
+Running the Application
+-----------------------
+
+The following steps demonstrate how to run the ``dpdk-pdump`` tool to capture
+Rx side packets on dpdk_port0 in :numref:`figure_packet_capture_framework` and
+inspect them using ``tcpdump``.
+
+#. Launch testpmd as the primary application::
+
+ sudo ./app/testpmd -c 0xf0 -n 4 -- -i --port-topology=chained
+
+#. Launch the pdump tool as follows::
+
+ sudo ./build/app/dpdk-pdump -- \
+ --pdump 'port=0,queue=*,rx-dev=/tmp/capture.pcap'
+
+#. Send traffic to dpdk_port0 from traffic generator.
+ Inspect packets captured in the file capture.pcap using a tool
+ that can interpret Pcap files, for example tcpdump::
+
+ $tcpdump -nr /tmp/capture.pcap
+ reading from file /tmp/capture.pcap, link-type EN10MB (Ethernet)
