=============
ovs-tcpundump
=============
Synopsis
========
``ovs-tcpundump < <file>``
``ovs-tcpundump -h | --help``
``ovs-tcpundump -V | --version``
The ``ovs-tcpundump`` program reads ``tcpdump -xx output`` from stdin,
looking for hexadecimal packet data, and dumps each Ethernet as a
single hexadecimal string on stdout. This format is suitable for use
with the ``ofproto/trace`` command supported by ``ovs-vswitchd(8)``
via ``ovs-appctl(8)``.
At least two ``-x`` or ``-X`` options must be given, otherwise the
output will omit the Ethernet header, which prevents the output from
being used with ``ofproto/trace``.
Options
=======
* ``-h`` or ``--help``
Prints a brief help message to the console.
* ``-V`` or ``--version``
Prints version information to the console.
