 160 Testpmd Command-line Options
 161 ----------------------------
 162
 163 The following are the command-line options for the testpmd applications.
 164 They must be separated from the EAL options, shown in the previous section, with a ``--`` separator:
 165
 166 .. code-block:: console
 167
 168     sudo ./testpmd -c 0xF -n 4 -- -i --portmask=0x1 --nb-cores=2
 169
 170 The commandline options are:
 171
 172 *   ``-i, --interactive``
 173
 174     Run testpmd in interactive mode.
 175     In this mode, the testpmd starts with a prompt that can be used to start and stop forwarding,
 176     configure the application and display stats on the current packet processing session.
 177     See :ref:`testpmd_runtime` for more details.
 178
 179     In non-interactive mode,
 180     the application starts with the configuration specified on the command-line and
 181     immediately enters forwarding mode.
 182
 183 *   ``-h, --help``
 184
 185     Display a help message and quit.

 203 *   ``--coremask=0xXX``
 204
 205     Set the hexadecimal bitmask of the cores running the packet forwarding test.
