Hi,
Why is it not possible to create an attribute for a domain with 1:1 cardinality? That way a 1:1 relationship could be displayed in the list if needed.
In our network setup one MAC-address is linked to one IP address, one hostname and to one VLAN. I have created a class physicalinterface containing MAC addresses, and a class networkinterface containing the IP addresses, hostname and reference to a VLAN. The MACs and IPs should ideally be in different classes, as it should be possible to change the physical hardware (i.e. MAC) while retaining the network configuration.
I am actually trying to replace a flat Excel-sheet with a proper CMDB. In the Excel sheet hostname, MAC, ... are on one line. I could not find any other way of displaying 1:1 linked data into a list, so using an attribute seems the only way.
