Hello @[deleted] Im not sure how I want to proceed with this one just yet.
We will soon be adding a related documents to assets so when you click on asset you will see related documents you created for that asset. For example you could create a document called FW01_Interfaces. Then within that document create a table 3 columns for Interface Name, IP, MAC and add additional rows as needed for interfaces.
We will still keep the single field primary IP and MAC under assets.
Another option is to create a whole other table for asset_interfaces and relate to assets but may be redundant with documents.
Would the documents solution work for you?
