Note:: - - * The ``dpdk-pdump`` tool depends on libpcap based PMD which is disabled - by default in the build configuration files, - owing to an external dependency on the libpcap development files - which must be installed on the board. - 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. - - -Running the Application ------------------------ - -The tool has a number of command line options: - -.. code-block:: console - - ./build/app/dpdk-pdump -- - --pdump '(port=<port id> | device_id=<pci id or vdev name>), - (queue=<queue_id>), - (rx-dev=<iface or pcap file> | - tx-dev=<iface or pcap file>), - [ring-size=<ring size>], - [mbuf-size=<mbuf data size>], - [total-num-mbufs=<number of mbufs>]' - [--server-socket-path=<server socket dir>] - [--client-socket-path=<client socket dir>] - -The ``--pdump`` command line option is mandatory and it takes various sub arguments which are described in -below section. - - .. Note:: - - * Parameters inside the parentheses represents mandatory parameters. - - * Parameters inside the square brackets represents optional parameters. - - * Multiple instances of ``--pdump`` can be passed to capture packets on different port and queue combinations. - -The ``--server-socket-path`` command line option is optional. This represents the server socket directory. -If no value is passed default values are used i.e. ``/var/run/.dpdk/`` for root users and ``~/.dpdk/`` -for non root users. - -The ``--client-socket-path`` command line option is optional. This represents the client socket directory. -If no value is passed default values are used i.e. ``/var/run/.dpdk/`` for root users and ``~/.dpdk/`` -for non root users. - - -The ``--pdump`` parameters -~~~~~~~~~~~~~~~~~~~~~~~~~~ - -``port``: -Port id of the eth device on which packets should be captured. - -``device_id``: -PCI address (or) name of the eth device on which packets should be captured. - - .. Note:: - - * As of now the ``dpdk-pdump`` tool cannot capture the packets of virtual devices - in the primary process due to a bug in the ethdev library. Due to this bug, in a multi process context, - when the primary and secondary have different ports set, then the secondary process - (here the ``dpdk-pdump`` tool) overwrites the ``rte_eth_devices[]`` entries of the primary process. - -``queue``: -Queue id of the eth device on which packets should be captured. The user can pass a queue value of ``*`` to enable -packet capture on all queues of the eth device. - -``rx-dev``: -Can be either a pcap file name or any Linux iface. - -``tx-dev``: -Can be either a pcap file name or any Linux iface. - - .. Note:: - - * To receive ingress packets only, ``rx-dev`` should be passed. - - * To receive egress packets only, ``tx-dev`` should be passed. - - * To receive ingress and egress packets separately ``rx-dev`` and ``tx-dev`` - should both be passed with the different file names or the Linux iface names. - - * To receive ingress and egress packets separately ``rx-dev`` and ``tx-dev`` - should both be passed with the same file names or the the Linux iface names. - -``ring-size``: -Size of the ring. This value is used internally for ring creation. The ring will be used to enqueue the packets from -the primary application to the secondary. This is an optional parameter with default size 16384. - -``mbuf-size``: -Size of the mbuf data. This is used internally for mempool creation. Ideally this value must be same as -the primary application's mempool's mbuf data size which is used for packet RX. This is an optional parameter with -default size 2176. - -``total-num-mbufs``: -Total number mbufs in mempool. This is used internally for mempool creation. This is an optional parameter with default -value 65535. - - -Example -------- - -.. code-block:: console - - $ sudo ./build/app/dpdk-pdump -- --pdump 'port=0,queue=*,rx-dev=/tmp/rx.pcap' |
