OBM 2018.11 with OA 12.10 and Sys_SystemDiscovery policy
Among a lot of useful information, also the IP address and interface information (MAC) are discovered and added to the RTSM for a node. But there is no relation between IP address and MAC.
So it is not possible to see which IP is hosted on which interface although this is very useful information.
The request is to discover the IP addresses and on which interfaces they are hosted on.
