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.
+* The ``dpdk-pdump`` tool depends on the libpcap based PMD.
Test Environment
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
-----------------------
#. Launch testpmd as the primary application::
- sudo ./app/testpmd -c 0xf0 -n 4 -- -i --port-topology=chained
+ sudo <build_dir>/app/dpdk-testpmd -c 0xf0 -n 4 -- -i --port-topology=chained
#. Launch the pdump tool as follows::
- sudo ./build/app/dpdk-pdump -- \
+ sudo <build_dir>/app/dpdk-pdump -- \
--pdump 'port=0,queue=*,rx-dev=/tmp/capture.pcap'
#. Send traffic to dpdk_port0 from traffic generator.
