Then run configuration poll on the device - subnet should be recreated again.

Then click "Execute" button on the toolbar (or F9 key on the keyboard) and it should produce some output in "Output".

Do u mean just copy paste this command "for (p : $object.parents) println(classof(p), p.name .. " (" .. p.id .. ")" );"  at which text box when i already click "execute script" need to paste? It have three textbook "script from library", "parameters" and "source".

Thanks and appreciate your guide.

May i know where to go to "context menu" tab? Is it select device and right click then choose "execute server script"?

Thanks and appreciate your feedback

for (p : $object.parents) println(classof(p), p.name .. " (" .. p.id .. ")" );

It will output all containers and subnets where this node is present along with their IDs in brackets. You can use this ID to search under Entire network by entering #123 in the filter (replace 123 with actual id)

I just check the /31 not display in subnet object so i dont know how to delete it. All the device discovered has been put into container.

Thanks and appreciate your feedback

Then on conf poll subnet should be recreated again - check if the bug persists then.

I just fixed that, now /31 on peer-to-peer links are handled correctly. Fix will be included into upcoming patch release.

Best regards,
Victor
