Description
-----------
Specifies the port the server shall listen to. Either a single port can be
specified or an array of ports. If multiple ports are specified, a listener will
be automatically started for each port. Thus, no additional inputs need to be
configured.

Examples:

.. code-block:: rsyslog

   module(load="imudp") # needs to be done just once
   input(type="imudp" port="514")

.. code-block:: rsyslog

   module(load="imudp")
   input(type="imudp" port=["514","515","10514"])
