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=92t enable netflow on lagg0.X devices and I also couldn=92t 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=92t 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 =93vlan=94 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.
