I've deleted the cisco verbage for brevity, but that doesn't mean loops
won't be detected. It means that it will behave like any STP port in
forwarding state -- forward packets until it detects a loop.
The "problem" is that if you were to link the networks together using
portfast ports then it could take 5-20 seconds for the switch to get a
clue. (I've never seen it take longer if enough traffic to create a
problem was transiting the port)
