The values of "node\_name" does not correspond. It would be good to test it.  
For example

&nbsp;&nbsp;&nbsp;&nbsp;- fail:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;msg: Values of node\_name(s) do not fit  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: aggregate\_info|map(attribute='node\_name')|list|  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;difference(net\_interface|map(attribute='node\_name')|list)
