Probably a stupid question, but other than a mention of this in the help documentation, i'm trying to figure out what this column is for. On all my devices on my switches, the column is empty if I make it visible. I would assume, by the name of the column, that this might (or could) display the user of the device? If so, how do I get it to populate? If that's not what it's for, what is it for and where do I populate it?> Thanks.
