 The :ref:`librte_pdump <pdump_library>` library provides the APIs required to
 allow users to initialize the packet capture framework and to enable or

 usage is recommended for debugging purposes.

 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
+capture framework and acts 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
