Ilya, To add it: 1- You first need to know the ID of the object type PDU: open the view of a PDU object you've already created, then just leave the cursor on PDU (object type line). On the bottom of your browser appear the description of the object, finishing by {$typeid_2}, which is the ID for PDU object 2- Go to Main/Configuration/User Interface, open the change tab 3- Insert "{$typeid_2} or " in the "List source: IPv4-enabled objects" 4- Save and refresh a PDU object: IPV4 and IPV6 tabs should appear and also for every new PDU object Olivier Hi, RT floks! There is RT 0.19.11 instance. When the new PDU object is created, it has "Ports" sheet, but no "IP". So I can assign MAC address and link port only. Where to store his IP? WBR, Ilya
