7 EAL Command-line Options
8 ------------------------
10 Please refer to :doc:`EAL parameters (Linux) <../linux_gsg/linux_eal_parameters>`
11 or :doc:`EAL parameters (FreeBSD) <../freebsd_gsg/freebsd_eal_parameters>` for
12 a list of available EAL command-line options.
15 Testpmd Command-line Options
16 ----------------------------
18 The following are the command-line options for the testpmd applications.
19 They must be separated from the EAL options, shown in the previous section, with a ``--`` separator:
21 .. code-block:: console
23 sudo ./testpmd -l 0-3 -n 4 -- -i --portmask=0x1 --nb-cores=2
25 The command line options are:
27 * ``-i, --interactive``
29 Run testpmd in interactive mode.
30 In this mode, the testpmd starts with a prompt that can be used to start and stop forwarding,
31 configure the application and display stats on the current packet processing session.
32 See :ref:`testpmd_runtime` for more details.
34 In non-interactive mode,
35 the application starts with the configuration specified on the command-line and
36 immediately enters forwarding mode.
40 Display a help message and quit.
42 * ``-a, --auto-start``
44 Start forwarding on initialization.
48 Start forwarding, after sending a burst of packets first.
52 This flag should be only used in non-interactive mode.
54 * ``--stats-period PERIOD``
56 Display statistics every PERIOD seconds, if interactive mode is disabled.
57 The default value is 0, which means that the statistics will not be displayed.
61 Set the number of forwarding cores,
62 where 1 <= N <= "number of cores" or ``CONFIG_RTE_MAX_LCORE`` from the configuration file.
63 The default value is 1.
