The new 5-tuple swap engine swaps: source and destination mac address, source and destination address in ipv4/ipv6, source and destination port in UDP/TCP. The forwarding engine will parse each layer and swap it, and will stop when the next layer doesn't match. The mentioned headers of ICMP/ARP/Multicast packets will be swapped as well according to matching layers. usage: --forward-mode=5tswap Signed-off-by: Shiri Kuzin <shirik@mellanox.com> Acked-by: Matan Azrad <matan@mellanox.com> Reviewed-by: Ferruh Yigit <ferruh.yigit@intel.com>

Running the Application
|
|
=======================
|
|
|
|
EAL Command-line Options
|
|
------------------------
|
|
|
|
Please refer to :doc:`EAL parameters (Linux) <../linux_gsg/linux_eal_parameters>`
|
|
or :doc:`EAL parameters (FreeBSD) <../freebsd_gsg/freebsd_eal_parameters>` for
|
|
a list of available EAL command-line options.
|
|
|
|
|
|
Testpmd Command-line Options
|
|
----------------------------
|
|
|
|
The following are the command-line options for the testpmd applications.
|
|
They must be separated from the EAL options, shown in the previous section, with a ``--`` separator:
|
|
|
|
.. code-block:: console
|
|
|
|
sudo ./testpmd -l 0-3 -n 4 -- -i --portmask=0x1 --nb-cores=2
|
|
|
|
The command line options are:
|
|
|
|
* ``-i, --interactive``
|
|
|
|
Run testpmd in interactive mode.
|
|
In this mode, the testpmd starts with a prompt that can be used to start and stop forwarding,
|
|
configure the application and display stats on the current packet processing session.
|
|
See :ref:`testpmd_runtime` for more details.
|
|
|
|
In non-interactive mode,
|
|
the application starts with the configuration specified on the command-line and
|
|
immediately enters forwarding mode.
|
|
|
|
* ``-h, --help``
|
|
|
|
Display a help message and quit.
|
|
|
