Hi, I have noticed net graph has issues with device that have a period in their name. Either that is the case or something similar. I couldn’t enable netflow on lagg0.X devices and I also couldn’t use some of mpd's features(such as LAC) either. I believe there were other examples but those are the two that came to mind and they both use net graph - I couldn’t work out why things would work on em0 or lagg0 but not on em0.X or lagg0.X and as i did some trawling through logs I saw something which suggested an issue with the names so I changed all my sub interfaces into “vlan” interfaces and I was able to get full functionality in MPD and with net graph netflow. Now that I have made the change, I would also say it is a much more manageable way of doing things as well.
