@melvinsilva said in Spanning Tree Protocol - CompTIA Network+ N10-007 Prof Messer:
I had experience when "users" manipulate patch panel or switch and plug both end of the cable (patch cord) to the same switch, creating a physical loop, but STP blocks this and prevent network issues.
Yeah, having switches that have STP turned on by default can be such a life saver in those situations. One place I worked liked to put in unmanaged switches all over the place. Caused me multiple long nights just tracking down which switch was the issue and then finding the loop cable. I knew exactly what was going on, finding it without good documentation and people saying "Oh, there's another network thingy over here." was just so much.... fun.
