-Error: "invalid connection specified, expected connection=local, got ssh"
--------------------------------------------------------------------------
-
-**Platforms:** Any
-
-Network modules require that the connection is set to ``local``.  Any other
-connection setting will cause the playbook to fail.  Ansible will now detect
-this condition and return an error message:
-
-.. code-block:: console
-
-    fatal: [nxos01]: FAILED! => {
-        "changed": false,
-        "failed": true,
-        "msg": "invalid connection specified, expected connection=local, got ssh"
-    }

-
-To fix this issue, set the connection value to ``local`` using one of the
-following methods:
-
-* Set the play to use ``connection: local``
-* Set the task to use ``connection: local``
-* Run ansible-playbook using the ``-c local`` setting
