I read about "spanning-tree loopguard". I can't tell if this is in the "yeah, do it, everyone does" category... that is, if cisco support really wished it was the default on the switches. I also can't tell what the downsides are. I don't have a lab, I just have operational switches. I don't want to get surprised.
