To use this utility, one must have libpcap installed on the system. -Furthermore, DPDK must be built with ``CONFIG_RTE_LIBRTE_PDUMP=y`` and -``CONFIG_RTE_LIBRTE_PMD_PCAP=y``. - -.. warning:: - A performance decrease is expected when using a monitoring application like - the DPDK pdump app. - -To use pdump, simply launch OVS as usual, then navigate to the ``app/pdump`` -directory in DPDK, ``make`` the application and run like so:: - - $ sudo ./build/app/dpdk-pdump -- \ - --pdump port=0,queue=0,rx-dev=/tmp/pkts.pcap \ - --server-socket-path=/usr/local/var/run/openvswitch - -The above command captures traffic received on queue 0 of port 0 and stores it -in ``/tmp/pkts.pcap``. Other combinations of port numbers, queues numbers and -pcap locations are of course also available to use. For example, to capture all -packets that traverse port 0 in a single pcap file:: - - $ sudo ./build/app/dpdk-pdump -- \ - --pdump 'port=0,queue=*,rx-dev=/tmp/pkts.pcap,tx-dev=/tmp/pkts.pcap' \ - --server-socket-path=/usr/local/var/run/openvswitch - -``server-socket-path`` must be set to the value of ``ovs_rundir()`` which -typically resolves to ``/usr/local/var/run/openvswitch``. - -Many tools are available to view the contents of the pcap file. Once example is -tcpdump. Issue the following command to view the contents of ``pkts.pcap``:: - - $ tcpdump -r pkts.pcap - -More information on the pdump app and its usage can be found in the `DPDK docs -<http://dpdk.org/doc/guides/tools/pdump.html>`__. - Jumbo Frames ------------ |
