Should be easy. Create a template with only Network/Interfaces (for NICs) or Storage/Interfaces (HBAs) and use them afterwards as a part for new template-based objects. Remember:; You can use more than one template to create a new object.
the thing is, that we can enter network-data concerning the notebook. But by connecting the notebook to the switch, we would have to reenter the same info to the interface information of the switch to see this information in the switch-port overview given above.
It would be nice to enter the information once and get it in this overview without giving redundant information to the system.
Maybe a switch in the seetings-menue can enable the use to choose his preference on that.
