I've just migrated from a 3750 stack to a 3850 stack.  They were connected via trunk and all was well.   After the migration was complete, we disconnected the trunk and all devices lost connectivity on the new stack.    I cleared the arp table, but I'm guessing this may be due to something with STP.   This is the first Migration I've done in this manner (without a straight replacement) and I'm sure it's something simple I need to do.    Thanks in advance. ...

Here's the issue: I have one campus that isn't shaped completely vertical or horizontal.   Imagine the site as more of a horse shoe shape made out of buildings. When I do the campus view and have to choose the buildings, since some are diagonal, they overlap when you draw a shape for the building. Since the rectangles cannot be rotated, and they're overlapping, I can't really get a set dimension correctly, plus it warns that the areas are overlapping. I have the DWG files for the buildings, which are set at the same angles as the campus view.   I can crop them to be at more of a straight angle, but it won't match up correctly with the main campus drawing. I need some guidance by anyone that's come across this, as I don't KNOW if the campus view depends on exact scaling and overlap like the floors do.   I don't want to rotate the buildings differently from the campus view, if it's actually using the AP placement ON the campus view, if you catch what I'm saying. So far, for this campus, it's been a nightmare when getting things to match up.   My only option has been to draw the rectangles for the buildings a their native angle and position, and leave the floor and building drawings at the same angle to match up.  Unfortunately, this leaves me with few options in terms of dimension scaling.  I have no idea exactly how large the box is that I just drew, as it's not to the edge of the building.. but just out in space. ...
