Left icon of up arrow = device up status
Right icon of both direction arrows = verifying state (audit in-progress)
If it was a mismatch, then you'd see a strike through icon
And a yield symbol (triangle w/ exclamation mark) would mean that ther was an error trying to read config (or firmware/model not in the supported device library yet)
Typically, if you mouse-over the icons, there should be a popup reflecting the same.
