To add a new interface to Made4flow go to the options bar in the left corner and select the Routers option:
On the Routers screen, select the editing pencil for the Router where the new interface is located (where this new interface will be loaded):
Finally, select the option Load Interfaces, after loading the interfaces, search for it in the search field, or search for it manually among the pages with the interfaces and leave it as monitored (See the article How to Monitor Interfaces in Made4Flow):
Once this is done, your new interface will have been added to Made4Flow.
